对设置全钢桁架连梁和设置钢筋混凝土、钢桁架混合连梁的双层联肢剪力墙平面结构进行了拟动力试验和低周反复荷载试验，研究了不同工况地震波作用下剪力墙的时程响应，以及其破坏机理、承载力、滞回延性性能、耗能机理、刚度及强度退化机理。试验结果表明：全部设置钢桁架连梁的剪力墙的刚度分布合理，耗能机理及刚度强度退化机理符合联肢剪力墙抗震设计的要求。大震时，在保证较高耗能能力的同时能够维持较高的承载力和刚度，持续约束墙肢，抗震性能优于混凝土连梁联肢剪力墙体系，是一种较理想的连梁设置方案。

Pseudo-dynamic tests and low cyclic reversed loading tests on two-floor coupled shear wall planar structures were conducted ,and one is arranged with two steel truss coupling beams ,the other is arranged with a steel coupling beam and a RC coupling beam .The shear walls’ seismic response under different earthquake intensity was deliberated , Their failure mechanism , bearing capacity , hysteretic ductility , energy dissipation mechanism ,and stiffness and strength degradation mechanism were analyzed as well . The results show that the shear wall with two steel truss coupling beams has reasonable stiffness distribution .Its energy dissipation mechanism ,stiffness and strength degradation mechanism can fulfill the demands of coupled shear wall’ s seismic design :under rare earthquake ,it can maintain good bearing capacity and stiffness ,and keep restraining the walls .Its seismic performance is superior to RC coupling beams-coupled shear wall system .
