The modeling of the bottom flange access hole for both FEM and 3D involves applying loads to the plate around the access hole to analyze the critical stress regions and their values. To achieve this, the FEComposite results for Fx on the related tub girder, and at the location of the access hole, must be defined in the Bottom Flange Access Hole Load object.
To gather the related axial forces (specifically for the Strength Limit State),
1.Analyze the global model.
Then, on the FEA tab, go to Composite Element Forces (Sectional).
Navigate to the relevant stage for which you are interested in the results. The results can be viewed for the Construction Stages,
...or for Combination Cases, including LL cases, Composite/Non-composite cases, or for Limit States (max/min).
After specifying the case for viewing the reuslts , the result can be filetered to see onlt bootom flange results. For further clarification refer to video attached below.
After specifying the case, the results at the position (station) where the access hole will be created can be obtained and applied to the access hole plate object.
Plate: Specify the plate for which the analysis will be run.
Fx on Each Side: Specify the Fx force to be applied to the plate. Refer to the Info Panel above for further information on extracting the related axial force from the global model.
