SAP2000 NonPrismatic Pier Cap Beam
SAP2000 NonPrismatic Pier Cap Beam
(OP)
I have modeled a pier cap beam with non prismatic beams. When I see the extruded view it does not show how I wanted to model. In this case both top and bottom are tapered I just wanted the bottom to be tapered. Can anyone kindly suggest how I can model correctly? It is just that view is not working properly but the moment and shear values are just fine. I have attached the image file as well.

Attached are screenshots of your model with the correct insertion point assignment.
Top of your column is pin release which causes instabilities because both ends of the beam are unsupported. There were no assigned loads to the cap beam other than selfweight in the model that you attached.
