摘　　要：提出了一种新型联肢剪力墙结构,并通过低周反复荷载试验研究了其抗震性能.较系统地分析了该新型剪力墙结构的刚度及其退化过程以及承载力、延性、耗能、破坏机制和破坏特征等.通过同现有研究结果对比表明,高阻尼混凝土混合暗支撑联肢剪力墙具有明确的两道抗震防线和更好的耗能能力,比现有暗支撑双肢剪力墙抗震性能更好.In order to analyze the seismic performance of a new type of coupled shear wall with enhanced concealed bracings,an experimental study of the seismic performance was conducted.The structure stiffness and its deterioration process,bearing capacity,ductility,energy dissipation,failure mechanism and failure feature were analyzed systematically.Comparison with the existing research results shows that high damping concrete coupled shear wall with enhanced concealed bracings is more effective than RC coupled shear wall with concealed bracings.
