摘　　要：为了更好地研究该结构体系的震害规律,分析结构破坏机理以及抗地震倒塌能力,运用LS-DYNA软件对底框多层砌体结构进行了由损伤至倒塌破坏的全过程的模拟。研究结果表明:底层结构破坏,造成上部结构失稳,最终导致结构整体的倒塌,仿真结果和真实倒塌过程吻合较好。该成果利用模拟的可视化再现地震时建筑结构的倒塌过程,确定建筑结构的薄弱环节,对建筑结构抗震设计具有一定的指导意义。In order to research the rule of the earthquake damage of structural system thoroughly and analyze failure mechanism and the ability of resisting collapse, the whole process from the damage to the collapse of masonry structure with bottom frame is simulated using LS-DYNA software in this paper. The results show that the damage of bottom causes instability of the upper part which eventually leads to the collapse of the whole structure. The simulation results coincide with the real process of the collapse preferably. The result presents the whole process of the collapse at the earthquake action by using visual method, which proposes the weaknesses of structure. It has a certain guiding significance to the seismic design.
