摘　　要：为了研究双向单排配筋Z形剪力墙的抗震性能以及力学性能,本文设计了两个1/2缩尺的双向单排配筋Z形混凝土剪力墙模型,翼缘和腹板均为双向单排配筋。通过传力装置对模型顶端施加低周反复荷载,在试验的基础上,分析试件的滞回曲线特征、耗能能力、承载力、刚度变化以及各阶段的破坏特征。试验表明:在试验的最后阶段,剪力墙的墙肢在破坏很严重的情况下,剪力墙的节点基本保持完好。分析表明:在合理的设计下,双向单排配筋Z形剪力墙能够满足多层结构的抗震要求。In order to study the aseismatic propertity and mechanical capability on the residential structure of multi-story Z-shear wall structure with bi-directional single row of steel bars,two 1/2 reduced scale＇s Z-shear concrete walls with bi-directional single row of steel bars models are designed,separately along the web plate direction and the flange direction.In the process,the low-cycle repeated loads are imposed on the top of the models through the load-transferring devices,and the hysteresis curve,the energy dissipation capacity,bearing ability,stiffness change and the destructive characteristics of each stages and analyzed.This experiment indicates： in the last stage the node of the sheer wall stays firm despite that the wall limb has been seriously damaged,which proves that in reasonable design Z-shear wall structure with bi-directional single row of steel bars can satisfy the seismic requirements of the multi-layer structure.
