Hi Staad master sirs, I’m Trying with the Staad.pro model of a Rack system with Economic solutions - which consists of Hot Rolled Sections + Cold-Formed Steel sections, by using IS800 + IS801.
My entire members are only supposed to be Designed as Hot Rolled sections & Bracing members are Cold Formed sections.
Even After several efforts - I’m receiving lots of Errors
How to Fix these Errors. Help me...
NOTE: Torsion and deflections have not been considered in the design.

In your model you have used SELECT OPTIMIZED and by default it applies to all members in a model. But, as number 3 member is not a cold formed section, it is throwing such error.
I would suggest using Select instead of select optimized in this case to avoid errors. See below link for details.
