摘　　要：为了对双排配筋剪力墙和单排配筋剪力墙的抗震性能进行对比研究,本文设计了1个1/3缩尺的三层混凝土剪力墙结构模型,模型的一侧墙体为双向双排配筋,另一侧墙体为双向单排配筋。对其进行了低周反复荷载下的抗震性能试验研究,分析了其承载力、延性、刚度及其退化过程、滞回特性、耗能能力和破坏特征。研究表明:在墙体的配筋率相同情况下,由于单排配筋墙体钢筋的间距相对于双排配筋墙体钢筋间距小,其首先约束混凝土裂缝的几率更大,其平面内的抗震性能优于双排配筋剪力墙;由于剪力墙的翼缘和腹板共同工作,单排配筋剪力墙平面外的性能也可满足多层剪力墙结构设计的要求。In order to make comparative study on the seismic performance of RC shear wall with single row of steel bars and that with double rows of steel bars, an experiment was conducted, in which the low cyclic reversed load was applied to a 3 stories RC shear wall structure model of 1/3 scale. In the model, bi-directional steel bars of double rows were designed at one side while those of single row at another side. With experimental data, bearing capacity, ductility, stiffness and its degradation, hysteretic behavior, energy dissipation and failure phenomena of the model were analyzed. Comparing shear wall with single row of steel bars with that with double rows of steel bars, it is found that the former is superior to the latter with respect to seismic performance in plane, because single row of steel bars can prevent crack developing effectively. The spacing of the single row of steel bars is smaller than the interval between double rows of steel bars, although they have same steel bars. As the result of the collaboration of web and flange, out-plane working performance of shear wall with bi-directional single row of steel bars is applicable for multistory building.
