Hi everyone!
In my STAAD.Pro V8i (series 4) versión 20.07.09.31 I find that design parameters (according AISC 05) for built-up members STP, SNUG and CSP do not work at all. Neither the slenderness nor the working ratio of steel members have any change when I apply those parameters to the members subject to flexure/compression. Havs this problem been solved in a later version?
Thank you very much in advance.
