Hello everyone,<\/p>\n

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)<\/p>\n

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)<\/p>\n
