Hi,
I am a basic staad user, I needed to model wind load on a solid and the load is transferred to the steel frame the solid is resiting on. I have created a plate above the frame and I tried to model a basic 8 noded solid rectangle with steel material, I got several errors for instabilities at nodes of solid and plate.
Can anyone please let me know the process of modelling such case?
Please attach that model for the investigation.
