TheRick109 said:EngrRC - for bridges, which is my main area of practice, I’ve never had to consider secondary effects. If you follow AASHTO there are slenderness requirements that AISC doesn’t have. Kl/r is 120 maximum for primary members and 140 for secondary members in compression. Let me do some digging as I think there is commentary on these limits. If you do encounter the need to consider secondary effects I’d suggest using moment magnification instead of p-delta. Moment magnification is easier and a little more conservative than p-delta analysis. AASHTO and AISC have provisions for this method.
Again, let me do some searching in the codes and I’ll post anything helpful.
