| Abstract: | The finite element software SAP2000 was adopted to establish the frame structure model. With the bottom column destructed, the static nonlinear method was utilized to analyze the effects of floors on continuous collapse. The results show that when floors were considered stiffness and ultimate bearing capacity of the structure were respectively 1. 077 and 1. 291 times larger than when floors were not considered. |
