摘　　要：双向单排配筋剪力墙结构适用于多层住宅结构。为了研究不同构造及不同连梁剪跨比的节点抗震性能,进行了5个连梁与墙肢节点的低周反复荷载试验。较系统地分析了其承载力、刚度及其退化过程、延性、耗能、破坏机制和破坏特征等。试验表明,经过合理设计,这种双向单排配筋剪力墙节点可以满足抗震要求。RC shear wall with bi - directional single row of steel bars is applicable for multistory residence building. A low - frequency quasi - static cyclic loading experimental study on seismic performance of five joint models with different construction measures and shear-span ratios was carried out. The load- carrying capacity, stiffness and its degradation, ductility, energy dissipation and failure phenomena of each specimen were analyzed systematically. Experiments indicate that the joint with bi - directional single row of steel bars is able to satisfy the requirements of seismic design through rational designing.
