Abstract_Chinese:为深入研究采用HRB500级高强钢筋高强混凝土双肢剪力墙的抗震性能, 根据规范考虑不同混凝土强度等级、不同连梁跨高比两种因素设计了3片HRB500级高强钢筋与C60、C70高强混凝土双肢剪力墙试件, 通过对试件进行低周反复荷载试验来研究其抗震性能, 主要对试件的受力过程、裂缝发展、破坏机理、屈服机制、延性系数、耗能能力以及变形能力进行考察．试验结果表明：HRB500级高强钢筋在双肢剪力墙中可以充分发挥其强度高的特性; 连梁跨高比不小于2.5的双肢剪力墙耗能能力较好, 连梁塑性铰转动充分; 混凝土强度等级越高, 混凝土越脆, 试件延性系数、变形能力会相应降低; 按照规范设计的高强钢筋高强混凝土双肢剪力墙试件变形能力满足现行规范要求．
Abstract_English:For further research on the seismic behavior of HRB500 level high strength reinforced concrete coupled shear walls，three specimens of HRB500 level high strength reinforced concrete coupled shear walls were designed and the quasi-static tests were carried out according to building design code. The process of stress，crack development status，yield mechanism，failure mechanism，energy dissipation capacity，ductility and deformation capacity were discussed. The test results showed that: HRB500 level high strength steel in coupled shear wall could give full play to its characteristic of high strength; the coupled shear wall，whose couple beam spain-deepth ratio was not smaller than 2.5，had good energy dissipation，and the plastic hinge of couple beam rotated fully; if the concrete strength grade was improved，the ductility coefficient and the deformation capacity of the specimens would be reduced; the deformation capacity of high strength reinforced concrete coupled shear wall specimen designed according to building design code could meet the requirements of current specification.
