Hi i'm using select series 6 in STAAD. I have assigned the design parameter of KZ & KY value 1.0 & TMain value 300 for my roof bracing member. The property assigned for the member is double angle ISA100x100x10. After analysis the results shows it is failed in Slenderness.
To overcome this i has reassigned my kz and ky value as 0.5 and analysed. Again it shows the same results. Pls advice was it the problem with staad?
