How to model beam and shell together?

    • Balli

      Hello everyone,

      I have 8 platforms to calculate weight capacity. (Figure Model,model2 and model3) And my computer is not able to perform the analysis for shell models. Because of some platform models too big even I use symmetry. That's why I don't want to use shell models. I thought I can model beam and shell together. The general model will be beam and critical regions will be shell. I will use a rigid connection between them. But the problem is the center of gravity. When I transform the 3D to 1D lines are going different height because of the cross-sections. I'm moving them to the same level but at this time the model is changing. I mean the center of the solid model and the line are not going on the same height. If I move the solid to down, the geometry will change. Should I neglect that situation? It's really hard to explain what I'm trying to explain, but if you check the figure you'll see the red boxes that I want to highlight the regions. If I move the solid to down the connection will be changed. Is it acceptable? (Figure 1,2 and 3)

      Or the second option is to use the original center of gravity for all of them. But how can I connect these beams that are located at different levels? (figure problem2.1, problem2.2)
