Hello, I am pretty new to Staad. I am currently modeling a jacket 28" OD with a shell 22" OD inside the jacket. They are concentric. They are both welded at the ends and the shell has periodic spacer between the ends. What would be the best way to model it in Staad?
My current method has the shell pipe shape modeled next to the jacket pipe shape. The two shapes are connected with dummy members.
However, when I apply wind load to the jacket, the shell is taking wind load as well. Is there a way to prevent the shell in STAAD from taking the wind load? Thanks
