双向单排配筋Z形剪力墙抗震性能试验研究
|
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.
