The devastating earthquake not only caused huge economic losses, and caused a great threat to life. Shear wall structure as the lateral force resisting system emerges as the requirement. The computer simulation technology has been widely used in the field of civil engineering. Based on large-scale finite element analysis software ANSYS, we applied monotonic horizontal load to the coupled shear wall structure to simulate the horizontal seismic. By observing the process from cracks to the final destruction of the structure, we carried on the analysis to the structure bearing capacity and deformation performance, and concluded the destructive mechanism of the structure.%破坏性地震不但带来巨大的经济损失，同时对生命造成了极大的威胁。剪力墙结构作为双重的抗侧力结构体系应运而生。计算机仿真技术飞速发展，广泛应用于土木工程领域。本文采用大型有限元分析通用软件ANSYS，对双肢剪力墙结构顶点施加逐级增加的单调水平荷载，来模拟地震水平作用，观察结构裂缝出现、充分开展直至结构最终破坏的全过程，从而对结构的承载力和变形性能进行分析，得到结构的破坏机理。从而提高工程人员对结构剪力墙结构进一步认识，同时也为工程设计提供参考。
