The results of the elementary calculations and the static combinations (cases 1 to 19 on tables 1 and 2) are summarised in table 4.
The parameter chosen to represent the effect of each loading component, elementary or combined, is the maximum von Mises equivalent stress on the plate and shell elements representing the upper half of the container (lifting box, upper half shell, plate ends, flanges upturned channel located above the upper half shell, and angle stiffeners).
The parameter chosen to represent the effect of each loading component, elementary or combined, is the maximum von Mises equivalent stress on the plate and shell elements representing the upper half of the container (lifting box, upper half shell, plate ends, flanges upturned channel located above the upper half shell, and angle stiffeners).
This maximum stress on the above referenced assembly is computed in middle skin (membrane component) and upper and lower skins (membrane plus bending).
This maximum stress on the above referenced assembly is computed in middle skin (membrane component) and upper and lower skins (membrane plus bending).
The values in bold on table 4 identify the skin on which the membrane plus bending stress is maximum for a given load, and the bold underlined values identify the maximum stress among all the five tie-down configurations for each load case.
The values in bold on table 4 identify the skin on which the membrane plus bending stress is maximum for a given load, and the bold underlined values identify the maximum stress among all the five tie-down configurations for each load case.
The results of the calculations in the present document will be used to obtain the dynamic loads and cyclic loads, and to perform the fatigue analysis in a later report.

: 7. CONCLUSIONS AND RECOMMENDATIONS
This document is part of the work to demonstrate the fatigue strength capability of the tie-down and handling systems used on the FCC4 container. It constitutes the first stage of the approach, consisting in updating the existing FCC4 container model and determining the maximum stress based on static loading (self-weight, stacking of empty and full containers, tie-down), or quasi static loads (lifting), and the transport acceleration loads.

SUMMARY

This document is part of the work carried out in answer to the comments made by the DGSNR. These comments subject the FCC4 transport container to, inter alia, the demonstration that "the securing and handling systems have adequate resistance to fatigue"

[translation].

This is the first stage in updating the existing FCC4 container model to determine the maximum stresses occurring under static loads (self weight, stacking of empty or full containers, tie-down), or quasi-static loads (lifting), and loads due to accelerations during transport.

1. INTRODUCTION

This document is part of the response to the remark made by the DGSNR (reference [1]

email) which subjects the certification of the FCC4 transport containers to, inter alia, the demonstration that "the securing and handling systems have adequate resistance to fatigue"

[translation].

It contains the first step in the approach which consists in updating the existing FCC4 model and determining the maximum stress level based on static loads (self weight, stacking of empty or full containers, tie-down), or quasi static loads (lifting), and the transport acceleration loads, in accordance with the client's specification (reference [2]).

2. PARTS OF THE CONTAINER COVERED BY THE ANALYSIS

The FCC4 container is described by reference drawings [3] to [5]; figures 1 to 3 show a general view and detailed views of the upper and lower half shells.

The parts of the container which have a relevant function in tie-down or handling are the following:

  • the lifting boxes,
  • the upper half shell, on which stand the lifting boxes (including the end plates and the flanges for coupling with the lower half shell),
  • the upper half shell circumferential stiffeners (circular angle beams_),
  • the longitudinal stiffeners, in the shape of upturned channel, located above the upper half shell,

The welds in question are fillet welds, identified as follows on reference drawing and figures 4 and 5:

  • welds between each lifting box and the two reinforcing angle sections on both sides; there are 4 welding beads per box, with a - apothem,
  • welds between the extreme edges of each lifting box and the upper half shell, in the longitudinal direction; there are 2 beads per box, with a

-apothem,

  • welds -apothem which connects the upturned channel stiffeners to the upper half shell (longitudinal beads), and

the circumferential reinforcing angle sections (transversal and vertical beads). In order to better distinguish between them and independently from the identification of the other beads not covered by this study, that may be shown on reference drawing, the -

beads will be identified as follows:

longitudinal beads: - per stiffener, on both sides),

transversal beads: -

vertical beads: -

  • welds-this is a series of beads with a -apothem, located on each circumferential angle section reinforcing the upper half shell.

3. CONFIGURATIONS TO BE ANALYSED AND RELATED LOADS

All the configurations to be analysed are described in reference document [2]: a distinction is made between static situations (or steady-state conditions), and transport situations, which engender vibrations on the container due to variable acceleration levels transmitted by the deck supporting the container.

3.1. Steady-state conditions Static conditions are all conditions excluding those occurring during transport (see § 3.2).

This includes lifting during handling, which can be considered a quasi-static operating condition due to the low level of associated velocity and acceleration.

Reference [2] note identifies the following situations, which cover a series of similar but less penalising situations from the engendered stress point of view:

  • the case of an empty, discharged container, or zero-stress conditions: this is a fictitious status neglecting stresses due to the self weight of the container. It enables us to maximise the cyclic variation of the stresses compared to the other statuses. This configuration also includes all handling operations by a forklift truck, which do not concern the container tie-down devices identified in § 2,
  • empty storage: in this configuration an empty container standing on the ground may have 1 or 2 other empty containers of the same type stacked on top,
  • lifting: in this configuration, a full container is lifted by a lifting beam with 4 vertical strands (see reference note [6]); a dynamic amplification factor of 1.15 is applied: this is a bounding configuration for lifting an empty container or a container upper shell alone,
  • stacking of full containers: this configuration corresponds to two full containers standing on a deck with a third full container placed in the middle position on both of them, resting on two lifting boxes of each container, the upper container being tied down. This configuration is bounding for the following situations:

stacking of three untied full containers,

stacking of four empty containers (standing two by two vertically, in contact between them), the two upper containers being tied,

stacking of four empty containers (two by two vertically with contact between them), the two upper containers not being tied,

  • tying-down of full containers: in this configuration two full containers are standing on a deck, tied together by straps (see § 4 ). This is a bounding configuration for tying-down two empty containers or only one, full or empty, container.

It is not planned to tie-down containers superposed on two levels separately (3 or 4 in all): if they are stacked, only the upper level container(s) are tied-down; if the containers are not stacked, only the containers standing on the deck are tied-down directly.

AREVA REV. B PAGE 12 / 55

3.2. Transport configurations In addition to the steady loading conditions described in § 3.1, the transport configurations are associated to variable dynamic loads, which are represented by distributed accelerations of given levels along each direction.

There are three transport configurations: road, rail and sea.

Dynamic loads are applied in a static equivalent way by considering the mass of the full container without taking into account the damping effect exerted by the anti-vibration pads on the assembly suspended inside the container, and represented by the mass of the cradle, the frame, the doors and the two assemblies.

Reference [2] note gives the criteria for establishing the amplitude of acceleration per direction and the combination of accelerations according to the directions and the type of transport.

In the present study, unit accelerations are considered separately in each direction (vertical, transversal and longitudinal).

3.3. Elementary and combined loads Based on the classification set out in the previous paragraphs, each type of load is described by one or several elementary components (single action per origin and per direction).

According to the type of action and the direction, different boundary conditions can be applied to the elementary calculation.

Table 1 contains the detailed list of the actions, in sequence from 1 to 15 (third column of table 1 ). These actions are grouped, based on different applicable boundary conditions, into eight calculation cases (first column in table 1 ).

Elementary actions are then combined to create the static loads described in § 3.1 (cases 16 to 18 in table 2, column two) or partial combinations for further use, to define transport configurations (case 19 in table 2, column two).

This document is aimed to define the unit transport load cases in each direction (vertical, transversal, or longitudinal). The combination of the unit loads with appropriate acceleration amplitudes will be matter of a further document.

4. RETAINED TIE-DOWN CONFIGURATIONS

Tie-down is realized by pre-stressing the tie-down straps, positioned either on the lifting boxes or on the upper half shell of the container.

Reference [2] note identifies five enveloping configurations for transport, described by figures 6 to 10, taken from such a document. It should be noted that these figures represent the simplified case of two containers standing one on the other. Actually, either 3 or 4 containers are set on two levels or 1 or 2 containers are set on a single level. For all these cases, the figures are representative of the total number of straps per tie-down configuration and of the position of each strap.

The following cases are analysed:

  • case 1 (figure 6): container with 2 straps positioned close to the lifting box "internal" hole,
  • case 2 (figure 7): container with 2 straps placed on the upper half shell stiffener close to the lifting box "internal" stiffener,
  • case 3 (figure 8): container with 2 straps placed on the upper half shell stiffener between the lifting box "internal" stiffener and the paracentral one,
  • case 4 (figure 9): this is a container with 4 straps positioned as follows:

two on the upper half shell stiffener, close to the lifting box "internal" stiffener (as in case 2),

two on the upper half shell stiffener, close to the paracentral stiffener,

  • case 5 (figure 10): container with 3 straps positioned as follows:

two on the upper half shell stiffener, between the lifting box "internal" stiffener and the paracentral one (as in case 3),

one on the upper half shell stiffener, at the centre of the container (in the longitudinal direction).

5. FINITE ELEMENT MODELLING

5.1. Existing models The FCC4 containers have been studied in the past as described in notes [6] and [7]

concerning the lifting conditions and the regulatory stacking tests respectively.

A spatial shell finite element model was used for these studies. It represents either one quarter or one half of the container, depending on the type of study carried out.

5.2. Model modification description The current FCC4 container version is shown on drawings [3] to [5]. Figures 1 to 3, extracted from these drawings, show the actual structure of the container.

Compared to the configuration shown in [6] and [7] notes, modifications exist on the lifting box and the upturned channel stiffener welding beads, as well as the addition of reinforcing longitudinal plates on the gussets of the lower half shell.

All these parts have been made conform with the current configuration.

Figures 4 and 5 show the detail of the main welds to be analysed. Their characteristics are described in § 2.

5.3. Material and masses The containers are made of-carbon steel.

Mechanical properties are taken from A3 and

The characteristics at ambient temperature are as follows:

The total mass of an empty FCC4 container is taken as-that of the container loaded with two 14 ft assemblies is 5500 kg.

N°NEEL-F 2008 DC 118E1 A

AREVA REV. B PAGE 15/55

5.4. Meshing Figure 11 represents the model of one quarter of the container, used in the previous analyses (references [6] and [7]).

The load set to be used for fatigue analysis is complex and impossible to be correctly represented using this partial model.

At least one-half of the container has to be represented, with different sets of boundary conditions adapted to the applied loads in order to cover all the required configurations.

The model was therefore doubled in size in order to represent one half of a FCC4 container in the longitudinal direction, as shown in figures 12 and 13.

The global system of axes is centred on the section plane with the X axis parallel to the longitudinal direction, the Y axis transversal and the Z axis vertical and positive towards the top.

The mesh, which consists of linear shell finite elements, is compatible with the SYSTUS computer programme (reference [31 ]).

Figure 14 shows the distribution of the plate and shell thicknesses on the container.

Figure 15 shows the arrangement of three containers in the tie-down and transport configuration. However, this is not true modelling, which was limited to only one container.

In the modelled configuration, the container is either in the left lower position and receives the loads due to the container standing on it and its tie-down system, or it is tied-down with its counterpart on the lower level.

N°NEEL-F 2008 DC 118E1 A

AREVA REV. B PAGE 16/55

5.5. Boundary conditions and loads Due to the complexity of the applied load set, and taking into account the symmetries, eight sets of boundary conditions have been used with three of them varying according to the applied tie-down conditions.

The actions of the tie-down straps were modelled by elastic connections specific to each tie-down case.

Table 3 gives the description of the applied conditions, according to type. Figures 16 to 23 show the boundary conditions for cases 1 to 8 in table 1 (column 1) and are supplemented by figures 24 to 28 for the elastic connections, variable in number and position according to the 5 tie-down cases analysed.

The tie-down load (reference [2]) is alwa s described by the equivalent of a vertical force and a transversal horizontal force of each one, representing pre-stressing, and by a longitudinal horizontal force of 1/2 of the previous value, to take into account the effect of friction. These values are conservative and constitute an increase of 15% over the maximum tension achieved during testing with 5-ton straps.

In order to validate the assumptions concerning the boundary conditions, the three following conditions have to be complied with for all tie-down configurations in actual operation:

  • adjoining containers are in transversal contact at the flanges joining the half shells by placing at least three stops between them (this condition is generally achieved by using parallelepiped wood inserts),
  • each container standing on a deck (road trailer, wagon or flat for maritime transport) butts transversally against its pads, excluding the installing clearances, in order to avoid the container sliding during transport,
  • each container standing on a deck (road trailer, wagon or flat for maritime transport) butts longitudinally against its pads, excluding the installing clearances, in order to avoid the container sliding during transport, The last two conditions have to be confirmed for all transporters and in all tie-down configurations in order to protect the containers against any risk of sliding, which would lead to unacceptable excessive stress and affect the stability of the tie-down arrangement.

The following paragraphs describe load cases 1 to 8 in table 1. These include identification of the elementary load components 1 to 15, all the boundary conditions applicable and the reference to the corresponding figures.

The signs chosen for the loading components described in table 1 maximise the stresses.

6. RESULTS

The SYSTUS calculations are executed separately for each of the five tie-down cases studied. Each one is a linear elastic calculation.

The results of the elementary calculations and the static combinations ( cases 1 to 19 on tables 1 and 2) are summarised in table 4.

The parameter chosen to represent the effect of each loading component, elementary or combined, is the maximum von Mises equivalent stress on the plate and shell elements representing the upper half of the container (lifting box, upper half shell, plate ends, flanges upturned channel located above the upper half shell, and angle stiffeners).

This maximum stress on the above referenced assembly is computed in middle skin (membrane component) and upper and lower skins (membrane plus bending).

The values in bold on table 4 identify the skin on which the membrane plus bending stress is maximum for a given load, and the bold underlined values identify the maximum stress among all the five tie-down configurations for each load case.

The results of the calculations in the present document will be used to obtain the dynamic loads and cyclic loads, and to perform the fatigue analysis in a later report.

7. CONCLUSIONS AND RECOMMENDATIONS

This document is part of the work to demonstrate the fatigue strength capability of the tie-down and handling systems used on the FCC4 container. It constitutes the first stage of the approach, consisting in updating the existing FCC4 container model and determining the maximum stress based on static loading (self-weight, stacking of empty and full containers, tie-down), or quasi static loads (lifting), and the transport acceleration loads.
