摘　　要：文中通过正交试验方法制备3种短肢剪力墙,低周反复加载试验测试其滞回特性、骨架曲线、刚度退化趋势、耗能能力以及自复位能力等特性,全面分析高强钢棒混凝土短肢剪力墙的抗震性能。结果表明,高强钢棒可显著改善短肢剪力墙的承载能力和自复位能力,位移角为3.5%时,与普通混凝土短肢剪力墙相比,高强钢棒混凝土短肢剪力墙的极限承载力增加67.03%,残余变形减少67.35%,且在高轴压比的作用下得到进一步提高。普通混凝土短肢剪力墙的耗能更高,同时轴压比对于试件的等效黏滞阻尼系数影响较小。In this paper,three kinds of short-limb shear walls were prepared by orthogonal test method.The hysteretic characteristics,skeleton curve,stiffness degradation trend,energy dissipation capacity and self-resetting ability of the short-limb shear walls were tested by low-cycle repeated loading test.The seismic performance of high-strength steel-bar concrete short-limb shear walls was comprehensively analyzed.The results show that high-strength steel rod can significantly improve the load-carrying capacity and self-resetting capacity of short-leg shear wall.When the displacement Angle is 3.5%,the ultimate bearing capacity of high-strength steel rod concrete short-leg shear wall is increased by 67.03%,and the residual deformation is reduced by 67.35%,and it is further increased under the action of high axial compression ratio.The energy dissipation of ordinary concrete short-leg shear walls is higher,and the axial compression ratio has little influence on the equivalent viscous damping coefficient of the specimens.
