摘要
双向单排配筋混凝土低矮剪力墙适用于多层住宅结构。对4个原型的剪跨比为1.0配筋混凝土低矮剪力墙进行了低周反复荷载试验研究,包括1个双向双排配筋混凝土低矮剪力墙和3个双向单排配筋混凝土低矮剪力墙。其中1个双向单排配筋混凝土低矮剪力墙加设暗支撑,用以研究暗支撑对这种新型墙体的作用。在试验研究的基础上,对比分析了各剪力墙的刚度及其衰减过程、承载力、延性、滞回特征、耗能能力及破坏特征。试验表明,经过合理设计,这种双向单排配筋混凝土低矮剪力墙可以满足多层住宅结构抗震要求。
The low-rise RC shear wall with bi-directional single row of steel bars is applicable for multistory residence building.In order to know the seismic performance of this shear wall,experimental studies on four low-rise RC shear walls with shear-span ratio 1.0 under a low-frequency quasi-static cyclic loading were carried out.Four low-rise shear walls include three shear walls with bi-directional single row of steel bars,one of which with concealed bracing,and one normal shear wall with bi-directional double ...
