摘　　要：屈曲约束钢板联肢剪力墙结构通过在整体墙中部开设竖向贯通的洞口并均匀布置屈曲约束钢板组件来改进传统联肢剪力墙结构的抗震性能。通过算例对比了整体墙及基于该结构改进的屈曲约束钢板联肢剪力墙结构在地震时程作用下的动力响应,发现了后者在减小地震响应上的优越性,具有良好的抗震性能。同时,提出了屈曲约束钢板联肢剪力墙的弹塑性分析简化模型,并根据理论分析,给出了简化模型中相应参数的设计公式。最后通过原模型及简化模型在地震时程曲线下的动力响应,验证了所提出的弹塑性分析简化模型的准确性和高效性。Coupled shear walls with buckling - restrained steel plates ( CSW - BRSPs ) can improve the seismic behavior oftraditional coupled shear wall structures by integrating the buckling - restrained steel plates into wall piers.This papercompares the dynamic response between solid cantilever walls and CSW - BRSPs under seismic excitation and finds thatthe latter one is able to reduce the dynamic response fundamentally , demonstrating its inherent superior seismicperformance.Meanwhile , this paper proposes a simplified model for analyzing the elastic - plastic behavior of the CSW -BRSPs.Theoretical analysis also provides design formulas to establish important parameters in the proposed model.Finally , the accuracy and efficiencyof new method is verified through the comparison between CSW - BRSPs and theresponding simplified model based on time- history analysis.
