1. ' Support Number 202, Type A4

References:

1. Gibbs & Hill, Inc. Drawing 2323-El-0700-01-S

2. Brown & Root, Inc. Drawing FSE-00174 The referenced support is the only support located on a straight segment of cable tray. The support does not provide longitudinal restraint.

Please provide Cygna with justification and documentation to show that:

e- The affected cable tray segments are adequately supported to prevent overstressing of the trays, and, e Support 202 is capable of resisting all applied forces.

2. Eccentric Loads and Connections l 2.1 Cable trays are attached to supports by friction type or heavy-duty tray clamps. The former type resists transverse and vertical loads while the later resists transverse, vertical and longitudinal loads. The-connection details for these clamps require that they be bolted or welded to the top of the cable tray support beam. A typical connection is shown in Figure 2A. Such connections provide a load transfer which is eccentric to the major axis and to the shear center of the channel sections typically used in the cable tray support designs. As a result, several effects are not considered in the design of the supports.

2.1.1 Major and Minor Axes Flexure As noted in Figure 2B, the location of the transverse load, Ph , is eccentric to the major axis by a distance d/2, where d is the channel depth. The effect of this eccentricity is an increase in major axis bending. Minor axis bending will occur because P h is eccentric to the minor axis by a distance of (g-x) where g is the gage distance and x is the location of the neutral axis relative to the back of the channel web.

2.1.2 Torsion due to Vertical Loads As shown in Figure 2C, vertical cable tray loads are applied

) eccentrically to the shear center of the channel section which induces torsional moments into the beam. Cygna has

-CABLE TRAY SUPPetT REVIEW WESTIONS noted that only beam members for Regular Case cable tray supports Details Aj, Bj and Ci and Detail SP-7 with brace have been analyzed for the effects of eccentrically applied vertical loads. Cygna is currently reviewing these calculations. No other cable tray supports have been analyzed for the effects of torsion due to vertical loads.

2.1.3 Torsion Due to Longitudinal Loads 1As shown in Figure 2C, longitudinal cable tray loads are applied , eccentrically to the major axis (X-X) of the channel section which induces torsional moments into the beam member. Cygna has noted that only Detail SP-7 with brace has been analyzed for the effects.of eccentrically' applied 1oads.

2.2 Eccentric Connections The cable tray supports are primarily constructed.of channel sections for the hanger and beam members and angles for bracing

. members. (For Cygna's concerns regarding angles, reference Cygna's letter 84056.027,~ question 2.) Figure 2D shows the eccentricity between the neutral axis of a typical beam and hanger connection.

- Cygna has noted that the effect of this joint eccentricity has not been considered in the design calculations.

Please provide Cygna with documentation showing the cable tray

. supports are capable of resisting the applied loads when the effects of the eccentricities described above are considered.

s3. Load Combinations

Reference:

1. Cygna . Technical File 83090.11.2.1.50.

Gibbs & Hill performs the load combination for support member forces by combining the dead load component with the vertical seismic component

, before the seismic components are combined by the' square root of the sum

- of the squares .(SRSS) method. - This is Gibbs & Hill's simplified method. Cygna had previously noted that the above method was incorrect.

because the dead load component was to be added to the SRSS of the

-vertical and ~ horizontal seismic components. Gibbs & Hill terms this combination the exact method, i

l: - To satisfy Cygna's concerns, Gibbs & Hill performed an evaluation to

[ compare the results of-the exact combination to the simplified L

combination -(Reference 1). This evaluation showed that the simplified method underestimated the resultant member stresses and anchor bolt loads by no more than 5% when compared with results from the exact method.

In general, the combinations used by Gibbs & Hill to qualify the acceptability of their simplified method is incorrect because it combines the seismic and dead load accelerations without considering the individual component's effect on the forces in the support members. The configuration of the support was not considered in the qualification calculations. Cygna performed an evaluation of the frames shown in Figures 3A, 38 and -3C for various aspect ratios (H/L for two-way frames H/L and H/d for three-way frames and L/B for cantilevers). The results are shown in Tables 1 through 3 for the Auxiliary, Safeguards, Electrical and Fuel Buildings.

The tables show that when the generic accelerations are used in the support design the simplified combination method is acceptable for all elevations of the four buildings except elevation 899'-6" in the auxilary building, which is acceptable since supports on this elevation were designed specifically for higher accelerations. When the elevation-specific accelerations are employed, the simplified combination method results in reactions which are 4 to 16 percent _ smaller than the exact combination.

Cygna is not requesting a response to this discussion. However, Cygna believes this information should be considered in the preparation of future responses to Cygna's questions where the cumulative effect of design discrepancies is evaluated.
