With framing systems, consisting of braced frames with rigidly jointed members or unbraced frames (sway frames) with flexibly jointed members, or unbraced (sway) frames with rigidly jointed members, or frames with semi-rigidly jointed member connections, columns attract significant bending moments and therefore the appropriate procedure is to carry out either a second-order analysis or the first-order analysis followed by moment amplification for all members subject to bending and compressive axial force.
