摘　　要：联肢钢板剪力墙能通过连梁耗能实现多重抗侧体系,其优良的抗震性能被越来越多的学者研究论证。本文基于能量平衡原理和Chao和Goel提出的弹塑性层剪力分布模式,预设目标侧移及屈服机制等性能参数,归纳出完整的联肢钢板剪力墙结构塑性设计流程,并采用该方法基于8度(0.3g)抗震设防条件下设计了12个联肢钢板剪力墙结构算例。利用有限元分析软件ABAQUS对结构进行了Push-over分析,研究了刚度退化、构件屈服顺序和结构整体变形等方面的结果。结果表明:设计算例能够实现多重抗震机制,并满足预期性能目标。Steel plate shear wall realizes multiple lateral force resisting system through the energy dissipation of the coupling beams,many scholars has studied it for its excellent seismic properties.Based on the principle of energy balance and Chao’s elastic-plastic shear distribution model,target lateral drift and yield mechanism are preset.,Authors summarizes a complete plastic design process of coupled steel plate shear wall structure.Using this method,12 coupled steel plate shear wall structures were designed under the condition of 8 degree(0.3g)seismic fortification.The push-over analysis of the structures was carried out by using the finite element analysis software ABAQUS.This study discusses about the results of stiffness degradation,member yield sequence and overall deformation of the structure.The results show that examples can realize the mechanism of multiple seismic resistance and reach the expected performance target.
