Abstract: To study the progressive collapse process of structures, a method to apply instantaneous load was adopted to simulate the progressive collapse of a multi-story plane steel frame with a failed middle column at the first story by using the large deformation and dynamic finite element software LS-DYNA. The analysis results show that the progressive collapse resisting capacity of steel structures can be remarkably improved by increasing the failure strain of the structural material.

Key words: multi-story plane steel frame, progressive collapse
