| Abstract: |
In this paper, parametric analyses are conducted with fishbone-shaped models considering the strength deterioration of members in order to investigate the complete-collapse behavior of steel moment frames. The column overstrength factor and width–thickness ratio are adopted as parameters. In most of the cases, the collapse mechanism varies from the total-collapse type to the story-collapse type due to strength deterioration by local buckling. The analytical results show that the collapse mechanism at the time of complete collapse affects the energy capacity. |
