摘　　要：通过对仅与上、下框架梁连接的两边连接非加劲、十字加劲和对角交叉加劲低屈服点钢板剪力墙与非加劲Q235钢板剪力墙的低周反复荷载试验研究,揭示了各试验试件的破坏模式、力学性能和耗能机理,给出了各试验试件的滞回曲线、骨架曲线、等效黏滞阻尼比等滞回性能指标。试验结果表明:低屈服点钢板剪力墙拥有良好的塑性性能和耗能能力,设置加劲肋后其滞回性能得到进一步的提升。Through the psudo static load test on four steel plate shear walls only connected with the beams of the frame,including the ones made of low yield point without unstiffener,with cross-stiffener,and diagonally stiffener and the one made of Q235 steel without stiffener,the failure mode,the mechanical property and the energy dissipation mechanism of the steel shear wall as well as its hysteretic behavior indexes,such as the hysteresis curves,the skeleton curves and the equivalent viscous damping ratio were revealed. The test resultes showed that the low-yield steel plate shear wall had excellent ductility and energy dissipation,and that setting up stiffeners could improve the hystereticbehavior of the shear wall.
