摘　　要：通过对3个钢筋混凝土空心剪力墙弯剪试件在低周反复水平荷载作用下的试验研究,探讨了两种不同配筋试件的破坏机理、变形特征、截面钢筋的应变情况及其极限承载能力。试验结果分析表明,墙端无暗柱的剪力墙发生承载力很低的脆性破坏。在空心剪力墙端部设置暗柱可以明显提高墙的承载力和延性。文中给出带暗柱空心剪力墙截面承载力的计算方法,计算结果与试验结果符合较好。Based on the test of three R. C hollow shear walls samples under low cycle and reverse horizontal load, the failure mechanism, the deformation feature, the strain of steel bar and the carrying capacity for two different reinforced samples are discussed. The testing result analysis indicates that the R. C hollow shear wall without end blind columns fails suddenly in a brittle of fashion with small carring capacity, but the wall with end blind columns can evidently increase carrying capacity and ductility. The method for calculating carrying capacity is presented.
