Title:

ISFSI Cask Storage Pad Concrete Shrinkage and Thermal Stresses Client: PG&E Job No. PGE-009 Purpose Of Calculation: The purpose of this calculation is to compute the forces and moments within the storage pad for the temperatures resulting from the heat of hydration during the curing process and from the shrinkage of the concrete. The ISFSI Facility will contain (7) pads, which will support (20) HI-Storm Storage Casks per pad. The results from this Calculation, along with the results from the seismic analysis, Calculation No. PGE-009-CALC-003, will be used in Calculation No. PGE-009-CALC-007 to evaluate the concrete per the design codes and to determine the size of steel reinforcement. NOTE: This Calculation is furnished as part of PG&E Contract No. 4600010841, Change Order No. 001 Scope Of Revision: This revision incorporates an additional thermal analysis for the heat generated during the initial curing of the concrete. It was therefore necessary to differentiate between this additional analysis and the original analysis presented in revision 0. The original analysis presented in revision 0 is referred to herein as the "constrained analysis", and the additional thermal analysis is referred to as the "unconstrained analysis". Revision Impact On Results: Provides additional thermal forces for evaluation in subsequent calculations.

Tumminelli ENERCON REVIEWER K. L. Whitmore APPROVED R. F. Evers SERVICES, INC. CALCULATION NO. PGE-009-CALC-006 REVISION 1 l Method of Review: // The calculation has been independently reviewed in accordance with the requirements of ENERCON Corporate Standard Procedure 3.01. The independent verification of the calculation was performed by a detailed review and check of the entire calculation. This included verification of inputs, methodology, results and conclusions as well as a check of the mathematical accuracy of the computations. Results: The calculation has been independently verified to be mathematically correct and to be performed in accordance with license and design basis requirements and applicable codes. Inputs are appropriate and are obtained from verified source documents. The calculation is sufficiently documented and detailed to permit independent verification. No assumptions are made other than conservative simplifying assumptions which are identified and do not require confirmation. The methodology used is appropriate and consistent with the purpose of the calculation. With the exception of the use of non-linear contact elements between the bottom of the concrete support pad and the surface of the rock, the analysis documented in this calculation is a straightforward, first order linear static analysis. The analysis is performed using ANSYS, a computer analysis code that is in widespread use throughout the nuclear industry and that is known to produce accurate results when utilized appropriately. The use of the non-linear contact elements has been separately verified in computer verification and validation report PGE-009-VVR-003. These elements are designed to transfer compression loads from the concrete pad to the rock but to not transfer any tension loads across the surface. This allows the pad to lift free from the rock in the model if the loads and geometry indicate that liftoff should occur. As documented in PGE-009-VVR-003, these elements have been shown to produce results that are consistent with theoretical values and hand calculations. Thus, the use of these elements in the analysis produces appropriate results. Thus, the analysis has been independently verified to be technically correct and to be consistent with license and design basis requirements. The results and conclusions accurately reflect the findings of the calculation.

Tumminelli ENERCON REVIEWER K. L. Whitmore APPROVED R. F. Evers SERVICES, INC. CALCULATION NO. PGE-009-CALC-006 REVISION I l ISFSI Pad Shrinkage and Thermal Analysis The purpose of this calculation is to determine the thermal and shrinkage stresses of the ISFSI storage pad and to provide thermal and shrinkage forces and moments. These forces and moments, together with the seismic forces and moments from a previous calculation (Reference 1), will be used to demonstrate that the design is compliant with the ACI Code and to size the pad reinforcement. This calculation follows the same general format as the seismic calculation (Reference 1) and makes extensive use of the analytical strategies presented there. Consequently, frequent references to that calculation will be made herein. The storage pad analyzed here is 105 feet N-S by 68 feet E-W and nominally 8 feet thick. The seismic calculation analyzed a 7.5-foot thick pad. That thickness is the thinnest that the pad can be, while 8 feet is the thickest. The surface of the pad is contoured to facilitate drainage, while the bottom is at a constant elevation. In a seismic event the design relies upon the mass of the pad to hold the casks and the pad down to the rock. Hence it is appropriate to use the minimum pad thickness for the seismic analysis, since this minimizes the pad mass. The use of the maximum pad thickness in this calculation is appropriate since this maximizes the applied heat and temperatures within the pad. The pad will be constructed using a leveling pad or "mud" mat. This "mud" mat will be an unreinforced concrete mat that will be placed upon the prepared rock to provide a level surface that will be used to construct the pad. The thickness of the mat will vary depending upon the constructor's technique to excavate the rock to a level surface. However, since the mat is not explicitly modeled, and since its properties are conservatively bounded by the properties of the rock, regardless of its thickness, the actual constructed thickness of the mat does not affect the results of this calculation. PG&E (Reference 2) provided the shrinkage and thermal data. The temperature data provided are the internal concrete pad temperatures as a function of time that occur as the heat generated by cement hydration is dissipated through the structure to the ambient. That calculation is for a specific concrete mix as specified by PG&E, and for a pad that is cast all at once, i.e., the underlying assumption is that the 105 by 68 by 8 foot concrete pad is instantaneously installed and begins to heat due to cement hydration. The calculation assumes that all the generated heat dissipates both upward to the concrete surface and then to air, and downward to the underlying rock strata. Heat dissipated out to the sides of the concrete is not considered. However, given the shape of the pad, the heat that may dissipate from the sides will be a small portion of the total and hence negligible. The actual amount of heat that will be dissipated from the sides of the pad will be a function of the type of concrete form, steel or wood, that is used. The steel form will allow more heat dissipation than the wood form but both will have a negligible effect on the pad responses computed here, though very some local and inconsequential stresses on the edges of the pad may arise. The heating transient due to cement hydration lasts for eight days. The shrinkage strains are a result of the moisture loss and the moisture gradient that is established in the concrete. The shrinkage process is very slow, reaching maximum shrinkage at 117 days, and therefore,

Tumminelli ENERCON REVIEWER K. L. Whitmore APPROVED R. F. Evers SERVICES, INC. CALCULATION NO. PGE-009-CALC-006 REVISION 1 does not occur within the same time frame as the heat up due to cement hydration. Hence, the two effects can be considered separately. Three separate analyses are performed; two for the thermal stress analysis and one for the shrinkage stress analysis. The two thermal stress analyses bound the conditions in the field. The first analysis considers the pad to be constrained to the rock in both the horizontal directions while allowing lift-off from the rock if conditions warrant. This is the condition described for slabs in ACI 207 (Reference 4). The second analysis allows the pad to slide freely on the rock surface in both horizontal directions. This is a very conservative assessment. The possibility that the pad will freely slip on the rock is a condition not discussed in ACI 207. This analysis is performed in order to bound the condition where the pad might locally break bond with the rock. These analyses, or models, will be referred to herein as "constrained" and "unconstrained". Both thermal stress analyses are performed incrementally. Incremental temperatures at selected times are derived from the pad temperatures from PG&E (Reference 2). These are applied to the finite element models and the Young's modulus of the concrete is adjusted, to account for the strength gain and gain in stiffness, for each of the selected times. The total pad response at a selected time is the sum of all the individual responses up to and including the response at that time. The shrinkage stress analysis uses the constrained model and is performed in one execution. More detail is provided below. The nomenclature for the pad analyses Appendices uses no identifier for the constrained models. The unconstrained model Appendices all have the characters "NC", for No Constraint, embedded in their titles.

Temperature Data The pad temperatures through the thickness with respect to time were provided by PG&E (Reference 2). Numerical data is provided at the top surface (see Sheet 58, Reference 2) and in 0.5 foot increments through the pad thickness and for four feet into the rock beneath the pad, (see Table 3, Reference 2). This same data is provided graphically, see plots in Figures 5, 6 and 7 in Reference 2. These plots were examined and eleven times were selected for analysis. The times were chosen because they produce stresses that reasonably bound the maximum demand on the pad resulting from the distribution of temperatures considering the shapes of the curves relative to one another. The following times were selected and are shown in Table 1 below.

Beyond this point the temperature 4 feet from the top surface is colder and is cooling more rapidly than the temperature 6 feet from the top surface. 4.125 Temperature at pad/rock interface peaks 6.125 Temperatures through the thickness are declining at the same rate (more or less) 7.875 Temperatures through the thickness are declining at the same rate (more or less) The PG&E thermal temperature analysis (Reference 2) and, consequently, the current thermal stress analyses anticipate that the maximum pad forces and moments due to temperature will occur within the first few days of casting the pad. (This will be shown to be true.) This was based, in part, on the discussion provided in Reference 4, Chapters 2 and 2.1. It is especially true for the ISFSI pad because this pad is a high strength mass concrete structure. The concrete has a high proportion of cement and flyash. Therefore, the heat effects and resultant temperatures within the first few days of casting the pad will be the most severe thermal effects the pad will ever experience. Table 2 provides the temperatures above ambient at the selected times from Table 3 in Reference 2. The PG&E calculation uses a differencing scheme that does not provide temperature values at every depth at every time step. Where that occurred, linear interpolation was used to compute the required value from the data at adjacent depths, holding the time constant. Interpolation from one time to another was not performed.

These temperatures were input to the analyses along with a conservatively chosen value for the coefficient of thermal expansion for the rock, i.e., a low value.

2. Depth is the depth below the top surface of the pad.

3. The data in Reference 2 is presented in two ways. The first is in Table 3 where the elevation is referred to as "Depth,ft". This correlates to the Elevation column here. The second is in Figures 5, 6 and 7, where the data is presented in "ft from Top Surface". This is the Depth column here.

PGE-009-CALC-006 REVISION 1 Thermal Stress Analysis Considerations Regardless of the actual temperature distribution in the pad, since the pad sits on a rock base, that base will restrain the pad from free axial growth. As shown in Figure 1, the restraining force will produce a negative moment (tension on the top) in the pad. This will tend to lift the pad from the rock thereby altering the uniform dead weight reaction force that would otherwise occur. (The reaction distribution shown in the Figure is one of many that could exist.) This in turn will produce positive moment in the pad, relieving the stresses caused by the restraint of the rock. Creep, particularly in the first few days after casting, will allow the pad to "settle" down on to the rock thereby reducing the positive moment. Creep will also relieve the applied temperature stresses at the same time. Hence, from an energy perspective on the pad, with the temperatures and dead weight acting at the same time, the effects of creep will be to reduce the net stresses.

Both analysis models include contact compression only gap elements between the top of the rock and the bottom of the pad. The models rely upon a net vertical downward load to maintain numerical stability during the solution process. The analyses for the thermal case use eleven separate time steps (see discussion below) with incremental temperatures applied to the model with eleven different values for Young's modulus to model the effects of the concrete hardening with time. The constrained model analysis used 90% of the dead weight of the concrete (90% of 150 pcf) in the first time step and 0.9% of the dead weight in each of the subsequent ten steps. The unconstrained model analysis used 72% of the dead weight of the concrete in the first time step, 18% in the second, and 0.9% of the dead weight in each of the subsequent nine steps. The displacements are then monitored for the summed steps to ensure that the pad is always

PGE-009-CALC-006 REVISION I separated from the rock at the centerline of the pad, thereby maintaining the full effects of the deadweight moments in the analysis. It is recognized that summing individual nonlinear analytical results is not, in the strictest sense, theoretically correct. However, given that the bulk of the dead weight is included in the first load step, l and that the subsequent load steps are for essentially temperature loads only, the additional forces and moments added to this first load step are conservatively computed. This is because the compliance of a stiffer (harder) concrete pad with the rock would have the pad migrating the CG of the dead weight reaction forces toward the edges of the pad, generating more offsetting deadweight moment than is computed here (creep ignored) for the constrained model. Thus, though the specific sums of displacements and moments etc. may not be exactly theoretically correct as in an analysis that could actually invoke a creep law, if one were known, the results here, are conservative. The unconstrained model results in the pad curling upward at the corners. Thus the dead weight produces a vertical down deflection at the corners which results in moments that simply add to moments generating tension stress on the top of the pad. Shrinka2e Stress Analysis Considerations Shrinkage of the pad is significant for the top one foot of concrete. This shrinkage causes tensile stresses to occur on the top surface. These stresses will curl the corners of the pad and cause the pad to lift off the rock at the corners. The pad dead weight tries to keep the pad corners down on the rock causing additional tensile stresses on the pad top surface.

PGE-009-CALC-006 REVISION I Pad ANSYS Static Model Construction Description Since all loads are symmetric and since the pad is symmetric, only 1/4 of the pad and confining rock is modeled. The constrained model is a solid finite element model designed to maximize the confinement that the rock has on the pad. This technique reasonably maximizes the rock's resistance to the pad's shrinkage and expansion, and therefore provides conservative results. The rock is modeled up to the level of the pad surface, and for a sufficient distance in all directions to accurately capture the behavior of the pad. The unconstrained model utilizes only the vertical stiffness of the rock. The constrained and unconstrained models differ only in that in the constrained model the bottom of the pad is "stitched" in both horizontal directions to the top of the rock. In the unconstrained model the stitching is absent. As in the seismic calculation, rotations of the nodes are not included in the solution. Also, as in the seismic calculation, the model is constructed in the Cartesian coordinate system with X pointing West, Y pointing up and Z pointing North. The analyses for temperature are incremental wherein the temperature through the thickness and Young's modulus are varied with time, in eleven time steps, to model the heat up as well as the effects of strength gain, i.e., gain in Young's modulus, of the concrete. The analysis for shrinkage is performed in one step where both the equivalent shrinkage temperatures and the dead weight of the pad are applied. Since this model contains contact elements, these analyses are nonlinear and iterative. The geometry of the pad and rock is shown in Figure 2. The completed model with the finite element mesh is shown in Figure 3. All plots presented are taken from the same viewpoint as that shown in Figures 2 and 3. The viewing direction is X = -1, Y = 0.5, and Z = -1, i.e., looking slightly down and from the pad centerline toward the far corner. Occasionally, the viewing direction will be changed to show pertinent detail. Unless the change in view direction is obvious, it will be noted.

Figure 6 - Close Up of the Two-Foot Gap The rock is designated as Material Type 1; is assumed to be homogeneous and its properties are not varied with time. The hard rock as described in the seismic report is used for this analysis. This is the stiffest rock that is reasonably expected to exist beneath the pad to an extent that it could affect the thermal response. The stiffest rock is the only rock that needs to be considered since it provides the greatest restraint to the pad. The pad stresses analyzed with the soft rock will be lower than those analyzed with the hard rock. The unconstrained model analysis bounds this condition. The PG&E temperature calculation provides some modest heat up of the rock directly beneath the pad. A literature search on the Internet provided some values for the coefficients of thermal expansion. The lower bound of these values is the conservative value to use, since this results in the lowest rock thermal expansion, and hence the greatest restraint to the pad. A coefficient of thermal expansion of 5E-6 in/in/degree F is specified for the sandstone (soft rock), taken from the Stone University at www.coldspringgranite.com, and 8.3x10-6 in/in/degree F ( = l5x10-6 in/in/degree K/1.8) is used for the dolomite (hard rock), taken from www.ima-eu.org. Combining properties to arrive at a conservative set to use for analysis, the following values were used for the hard rock (see Table 6). Since the coefficient of thermal expansion of the concrete "mud" mat will be higher than 5.0x10-6, the value in Table 6 is conservative, regardless of the final thickness of the "mud" mat since the lower bound is the conservative value to use. Also, since the "mud" mat will be relatively thin and unreinforced, adjusting the Young's Modulus is not justifiable. I

The pad and rock models have coincident nodes at the bottom of the pad and at the top of the rock beneath the pad. In the constrained model these nodes are then stitched together in a manner that allows the pad to push/pull horizontally on the rock mass but does not allow the resulting curvature to affect the vertical stresses between the pad and the rock. These constraint equations act in combination with the contact elements described below. These constraint equations are absent in the unconstrained model. Since the nodes are coincident, stitching them together simply produces continuity without any internal moments to consider. Thus, interior to the pad, all the nodes at the bottom of the pad and the top of the rock are stitched in the X and Z directions. Along the edge in the XY plane of symmetry, all nodes are stitched in the X direction, and along the edge in the YZ plane of symmetry, all nodes are stitched in the Z direction.

PG__-009-CALC-006 REVISION 1_ l Loads and Analysis The thermal stress analyses are conducted using eleven Load Steps. The delta temperatures shown in Table 5 are applied and the pad material properties are specified for each Load Step. In Load Step I, for the constrained model, 90% of the pad dead weight is applied, and 0.9% of the pad dead weight is applied in each of the ten subsequent Load Steps to maintain numerical stability. (Concrete density was set to 135 pcf (90% of 150) and the vertical acceleration for the first load step set to 1.0G, and 0.01G for each of the ten subsequent load steps.) [The unconstrained model used 72% in Load Step 1, 18% in Load Step 2 and 0.9% in each of the nine subsequent Load Steps.] The results, from each Load Step analysis, are a complete set of pad/rock responses, i.e., reactions, displacements, stresses etc. The results for each time are the algebraic sum of the individual responses to that time. These are summed and stored as Load Cases. As an example, the pad response for the constrained model at 2.125 days is Load Case 6 and it is the sum of Load Steps 1 through 6. As a check, the delta temperatures and summed temperatures are output to provide a means to check the input data back to the source. The ANSYS output files that document the generation of the loads for each load step are provided in Appendices TH-Loads and THNC-Loads. Plots of the summed applied temperatures are provided in Appendix TPad-TH and are applicable to both thermal models. One plot from the Appendix for Load Case 7 is shown in Figure 14. The ANSYS output files that document the analyses together with the output delta temperatures and summed temperatures are provided in Appendices RPad-TH and RPadNC-TH. A comparison of the output temperatures with the temperatures in Tables 2 and 5 show them to be the same for both models. Each summed Load Case is then checked for equilibrium. The output files that document this check for equilibrium are provided in Appendices EPad-TH and EPadNC-TH. This data demonstrates that the overall equilibrium for the rock and the pad is satisfied. The shrinkage stress analysis is conducted in one load step. The equivalent shrinkage temperatures from Table 3 are applied along with the acceleration due to gravity. The concrete density was set to the full 150 pcf and the vertical acceleration to 1.0G. The ANSYS output file that documents the generation of the loads is provided in Appendix SH-Loads. The ANSYS output file that documents the analysis together with the output equivalent temperatures is provided in Appendix RPad-SH. A comparison of the output temperatures with the temperatures in Table 3 shows them to be the same. The analysis is then checked for equilibrium. The output file that documents this check for equilibrium is provided in Appendix EPad-SH. This data demonstrates that the overall equilibrium for the rock and the pad is satisfied.

PGE-009-CALC-006 REVISION 1 Constrained Model - Pad Response - Displacements The displacements for the individual Load Steps are shown in Appendix LSPad-TH. There are three different displaced shapes. The first is shown in Figures LS-1 and LS-lA. The deadweight in this analysis is not enough to overcome the arching action caused by the restraining forces due to net thermal expansion of the pad (see Figure LS-1). However, enough deadweight is acting to force the pad down on to the rock at its edges, Figure LS-IA. And, the deadweight does affect the displaced shape. The maximum up deflection is not at the centerline of the pad. The second shape is shown in Figures LS-2 through LS-4. In these analyses, the restraining forces cause arching action, as in LS-1, but since the deadweight is very small, the pad arches up in two directions and is only supported at its corners, Figure LS-2A. The third shape is shown in Figures LS-5 to LS-1 1. In these analyses, the net thermal expansion is not enough to develop restraining forces of sufficient magnitude to overcome the applied temperature upward curvatures. In these cases, the deadweight stresses add to the applied net thermal stresses, i.e., tension on the pad top, but since the deadweight is small its effect is also small. The summed displacements of the pad for all the Load Cases are plotted in Appendix LCPad-TH to give some sense of expected deformations. The summed displacements at the pad centerline are computed in Appendix DPad-TH. To compare them to acceptable deflections, see Table 7. However, since the analysis is piecewise and sums separate nonlinear analyses, the summed displacements are not analytically exact. However, they do provide a reasonable sense of the pad's total deformation. Table 7 provides displacements for the bottom of the pad (node 113) and the top of the rock (node 133) both at the centerline of the pad. Plots of the pad vertical displacements for Load Cases 1, 2 and 7 are shown in Figures 15, 16 and 17. The displaced shape for Load Case 1, Figure 15, shows that the dead weight is not enough to force the pad down to the rock at its centerline. However, it does alter the arching action shape. The shape for Load Case 2, Figure 16, shows that the influence of the dead weight is reduced and the arching action dominates the response. In Load Case 7, Figure 7, arching action still dominates even though three Load Steps (5 to 7) were added. In each of these three Load Steps, as discussed before, the restraining forces are not enough to force arching action. However, the magnitudes of the forces involved are not enough to alter the arching action established by the summation of Load Steps 1 through 4. The pad appears to "float" owing to the addition of the vertical displacements at the pad edges from Load Steps 5 through 11.

Creep will reduce all the calculated deflections and stresses. Hence the expected deformations in the field are much less than these calculated values. Nevertheless, an often used value for deflections due to dead weight is 1/320 = 105x12/320 = 3.9 inches. See, for example, ACI 349-97, Table 9.5(a). As the data demonstrates, even these computed deflections are not severe.

PGE-009-CALC-006 REVISION 1 l Constrained Model - Pad Response - Stresses Pad stresses are plotted for Load Case 7 in Figures 18 and 19. The SX and SZ tensile stresses occur over nearly the entire top surface of the pad. A complete set of plots for all Load Cases is provided in Appendix STPad-TH. All the plots indicate roughly the same shape of stress field within the pad. This is a biaxial (X-Z) tension stress field at the top surface, and a maximum biaxial (X-Z) compression stress field just below the mid-height of the pad, and a biaxial compression stress field at the bottom of the pad. Pad stresses are provided in Table 8 to give a sense of the level of expected cracking. The values are the highest tensile and compressive stresses in both the X and Z directions, the maximum tensile principal stress (F MaX, and the minimum compressive principal stress 03 Min The concrete compressive and tensile strengths are derived from the Specified f, from Table 4. The ANSYS output file that documents the post processing for these stresses is provided in Appendix SPad-TH. The stresses indicate that in the absence of creep, cracking would be expected to occur. However, the data also shows that significant creep and consequent reduction of these stresses will occur. The values of a 3 m. in Load Cases 1 to 3 greatly exceed the expected f,. The a3 is plotted in Figure 20 for Load Case 3 and again in Figure 21 for Load Case 7. The extent of the stress field is very local and confined to the pad corner throughout the curing heat up. The a, is plotted in Figure 22 for Load Case 3 and Figure 23 for Load Case 7. These show that the a1 is not local and the extent of expected cracking, and therefore, required crack control reinforcement is significant.

Evers REVISION 1 Constrained Model - Pad Response - Internal Forces The pad internal forces and moments will be used to size reinforcement and assess the level of expected cracking. The pad was divided into strips as discussed in Reference 1. Since the model here is only 1/4 of the model used in the seismic analysis, modeled in the +X, +Z quadrant, the centerlines of this model lie at lines 5 1/2 and C of the seismic model, see Figure 29, Reference 1. Since all the maximum stresses occur at the planes of symmetry, or nearly so, only the internal forces on lines 5 1 and C are computed. (Though the Mx symbol does not appear at the edges in all the plots in Appendix STPad-TH, the stress contour maps indicate that the stresses are very close to the maxima at the edges.) The sign convention for these forces is also discussed in Reference 1. In this analysis, lines 5 I/2 and C are the "last section" as described in Reference 1. The forces are provided in Table 9. The ANSYS output file documenting the post processing of these values is provided in Appendix FPad-TH. The values from the model are provided as well as the Design Values to be used for sizing the reinforcement.

Unconstrained Model - Analysis Results - Thermal Stress Analysis The applied temperatures are the same for this model as for the constrained model. The plots shown in Appendix TPad-Th are therefore applicable. The numerical results are provided in Appendix RPadNC-TH. Unconstrained Model - Pad Response - Dismlacements The displacements for the individual load steps are shown in Appendix LSPadNC-TH. The displaced shape for the first nine load steps is the shape typically found in the literature where the free corner curls upward. The last two load steps, 10 and 11, have the opposite shape since these two load steps are for cooling loads. As the shapes show, the dead weight of the pad in not enough to force the pad to be compliant with the rock. The summed displacements of the pad for all the Load Cases are plotted in Appendix LCPadNC-TH, again to provide some sense of the magnitude of the expected deformations. The displaced shape for all eleven load cases shows that the free corner curls as opposed to the constrained model where the center of the pad arches. A plot of the displacements for Load Case 6 is shown in Figure 24 below. The upward displacements of the pad corner are summarized in Table 10.

Unconstrained Model - Pad Resuonse - Stresses The pad stresses are plotted for Load Case 6 in Figures 25 and 26. Plots of Sx and Sz for all the Load Cases are provided in Appendix STPadNC-TH (see Figures STNC-1 through STNC-22). These plots show that from 0.25 days to 3.125 days both the top and bottom surfaces are in biaxial (X-Z) tension and the middle portion of the pad is in biaxial compression (see Figures STNC-1 to STNC-16). The time 4.125 days is a transition where the maximum tension stresses lie beneath the surfaces due to cooling (see Figures STNC-17 and STNC-18). Finally, as the pad cools, and the concrete hardens, the stresses reduce in magnitude and evolve in to a complex stress state (see Figure STNC-19 to STNC-22). A summary of the applied stresses is provided in Table 11. Comparing the stresses in Table 11 with those in Table 8 show that allowing the pad to slide on the rock reduces the applied stresses, in some cases significantly, compare the (Y3 Mn columns. The distribution of stress within the pad however, is markedly different. In the constrained model there is a net moment to the pad, hence tension on the top and compression on the bottom. While in the unconstrained model there is no net moment, hence the stress field with tension on both the top and bottom and compression in the middle.

• f = 6.7 Cfl7 In order to numerically assess the internal force distributions of the stress field within the pad, use is made of the ANSYS plot path capabilities. This feature allows stresses to be plotted along a specified path, i.e., a line defined within the finite element mesh. An examination of the stress plots, STNC-1 to STNC-22, shows that there are three locations where the stresses reach maximum values for the analyzed load cases. Thus, three paths were established. They are shown in Figure 27 below. The first is referred to as "X side" where X is 285.6 in. and Z is 0.0, the second is called "Center" where both X and Z are 0.0 and the third is called "Z side" where X is 0.0 and Z is 510.0 in. All three paths extend from the top of the pad to the bottom. Thus in the stress path plots, 0.0 is the top of the pad and 96 is the bottom.

A review of the stress contours indicates that the most demanding stresses and hence internal forces will be from Load Cases 5, 6 or 7. Path plots for Sx at X side, Sx and Sz at the Center and Sz at Z side are provided in Appendix STPadNC-TH, see Figures STNC-24 to STNC-32 for these load cases. A review

Normalization to a 17-foot wide strip has been performed. Values for strip 5 1/2 - 6 factored by 2, and values for strip 8-10 factored by 1.7. Summary and Conclusions This calculation computes applied internal forces due to pad heat up due to cement hydration and subsequent pad shrinkage. The values to be used in subsequent calculations to assess the probability of expected cracking and to size the reinforcement are provided in Tables 9, 13 and 14, and Figures 28 to 33.
