【摘要】 为探讨不同连梁跨高比带暗支撑双肢剪力墙的抗震性能,进行了 2组连梁跨高比分别为 1. 0和1. 5的 4个 4层双肢剪力墙 1 /4缩尺模型的抗震性能试验研究。较系统地分析了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。结果表明,连梁跨高比相对小的带暗支撑双肢剪力墙抗震性能较好。承载力计算结果与实测值符合较好。更多还原

【Abstract】 In order to analyze the seismic performance of RC coupled shear wall with concealed bracings in different span-height-ratio of lintel beam, experimental study on seismic performance for 2 sets of four-floor scale models of RC coupled shear wall with concealed bracings was put forward. The span-height-ratio of the lintel beam of one set is 1.0, and the other is 1.5. The structure stiffness and its deterioration process, bearing capacity, ductility, energy dissipation, failure mechanism and failure feature are analyzed systematically. Through experimental analysis. it proved that RC coupled shear wall with concealed bracings is more effective in the smaller span-height-ratio of the lintel beam. The calculating results on bearing capacity of the specimens are found coincident with the actual measured ones.更多还原
