摘要:Based on the fluid-solid coupling method, the ANSYS/LS-DYNA software is used to simulate the collapse of a three-story steel frame considering floors under blast load, and analysis of dynamic response and failure mode of the steel frame is carried out under the influence of factors such as floors, position of opening, opening rate and opening floors. The results show that under blast load, the existence of floors adversely affects the collapse of the steel frame, and it is more likely to lead to the collapse of the steel frame that position of opening is directly above the detonation point, opening rate is smaller and opening floors are at bottom. The continuous opening of floors has no obvious influence on the collapse of the steel frame under blast load.
