A two-bay six-story moment-resisting steel structure was designed according to ATC 3-06 as an example, and its behavioral characteristics in inelastic range were observed through the inelastic analyses. The design concept of strong column and weak girder, which is usually implemented by the design rule that the sum of column plastic moments should be larger than that of girder plastic moments at the joints by some margin, cannot actually prevent the occurrence of plastic hinges in columns. The reason is clarified by the close investigation of inelastic behaviors around joints up to the point of the formation of a collapse mechanism. Based on the results of the study, a new design rule to ensure the prevention of plastic hinges in columns is suggested.
