摘　　要：为研究带聚苯板接缝的剪力墙对结构整体性能影响,对1片带聚苯板接缝剪力墙试件进行了有限元模拟,在验证有限元模型正确的基础上,为便于工程计算,将带聚苯板接缝剪力墙等效为折减厚度的普通剪力墙,并对带聚苯板剪力墙占比率不同的高层剪力墙住宅结构进行多遇地震下弹性分析。仿真和计算结果表明:采用带聚苯板接缝剪力墙可等效为30%厚度的普通剪力墙;工程算例中几种不同聚苯板接缝剪力墙占比率的剪力墙结构均满足现行规范中剪力墙结构弹性层间位移角要求;剪力墙结构中布置聚苯板接缝的剪力墙增大了结构周期,降低了结构刚度和层间剪力。In order to study the influence of shear wall with polystyrene plate joint on the overall performance of the structure,a shear wall specimen with polystyrene plate joint was simulated by finite element method.On the basis of verifying the correctness of the finite element model,the shear wall with polystyrene plate joint was equivalent to the ordinary shear wall with reduced thickness for the convenience of engineering calculation.The elastic analysis of high-rise shear wall residential structures with different ratios of polystyrene plate joint shear walls was carried out.The simulation and calculation results show that the shear wall with polystyrene plate joint can be equivalent to 30%thickness of ordinary shear wall.The shear wall structures with different ratios of polystyrene plate joint shear wall in engineering examples all meet the requirements of elastic drift ratio of shear wall structures in current specifications.The shear wall with polystyrene plate joint in the shear wall structure increases the period of the structure and reduces the stiffness and interstorey shear force.
