摘　　要：本文进行了10榀劲性钢筋混凝土开洞低剪力墙在低周反复荷载作用下的试验研究。结果表明,劲性钢筋混凝土低剪力墙延性相对较好,滞回曲线丰满,并有较强的塑性变形能力和耗能能力,承载力也有较大的提高。门窗洞口的存在对试件承载力有一定的削弱,但对延性和耗能能力则有一定的提高。采用劲性钢筋混凝土结构可有效地提高低剪力墙的抗震性能。10 specimens of steel reinforced concrete (SRC) low shear walls were tested under low-cycle reversed load in this paper. According to the results of the test and comparing with RC shear walls, it is found that SRC shear walls have better ductility, energy dissipation capability, shear strength, and fuller hysteresis loop. Although the area of opening reduces the shear strength but it increases the ductility and energy dissipation capability of the specimens. SRC structure can effectively improve the seismic capability of low shear walls.
