thread507-382979: Slender concrete column design in RISA 3D
Please reference http://www.eng-tips.com/viewthread.cfm?qid=382979
My question is why is RISA 3D still giving you a warning about exceeding 0.75Pc as specified in the moment magnification method if RISA is doing a pure elastic 2nd order analysis (NOT magnification method)? Is this check still required by the code? Is it to maintain a reasonable axial load? I thought that if we had stability problems these would be shown in the amplified moments (higher than 1.4 than the elastic moment) or in a p-delta instability.
