摘　　要：双向单排配筋剪力墙结构适用于多层住宅结构。本文进行了1个普通双向双排配筋混凝土中高剪力墙、2个双向单排配筋混凝土中高剪力墙和1个带暗支撑双向单排配筋混凝土中高剪力墙的低周反复荷载试验,以研究双向单排配筋混凝土中高剪力墙的抗震性能及暗支撑对这种新型墙体结构的作用。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,这种双向单排配筋混凝土中高剪力墙可以满足多层住宅结构抗震要求。The RC shear wall with bi-directional single row of steel bars is applicable for muhistory residential building. In order to measure the seismic performance of shear walls, a low-frequency quasi-static cyclic loading experimental study on four medium-height shear wall specimens was carried out. Two specimens were medium-height RC shear walls with bi-directional single row of steel bars, one specimen was medium-height RC shear walls with hi-directional single row of steel bars and concealed bracing, and another one was medium-height RC shear wall with bidirectional double row of steel bars. Based upon the experimental study, load-carrying capacity, stiffness and its degradation, ductility, hysteretic behavior, energy dissipation and failure phenomena of the shear walls were contrastively analyzed, and the effects of concealed bracing on the seismic performance of this shear wall were dis- cussed. It is shown that the medium-height RC shear wall with bi-directional single row of steel bars will be able to meet the requirements of seismic design for mnhistory residential building through rational design.
