| Abstract: | This paper analyzed the collapse procedure and present situation of a two-story steel frame,it was also pointed out that the structural collapse resulted from the improper structural design.Based on the analysis, improvements on the failure design were investigated,and the calculation method and formula of the minimum flange thickness of the steel beam supporting column without stifferner were proposed. |
| |
| Keywords: | collapse of building slenderness ratio of column discontinuous column flange thickness stifferner of beam longitudinal frame beam lateral stiffness construction sequence |
