摘　　要：通过2个带窗洞配筋砌块砌体剪力墙试件的拟静力试验,研究带窗洞配筋砌块砌体剪力墙的破坏形态、承载能力、变形能力等抗震性能以及墙体两端构造柱的影响。试验结果表明:试件为洞口两侧墙肢剪切破坏,洞口以下墙体有斜裂缝,但裂缝宽度不大;相对于无构造柱的试件,墙体两端设置构造柱的试件的水平力-位移滞回曲线略为饱满,名义屈服水平力和峰值水平力分别提高了约30%和20%,刚度退化较为缓慢;2个试件的极限位移角相同,均为1/90,满足大震作用下剪力墙结构的变形能力要求。To research the seismic behavior of reinforced block masonry shear walls with opening, including failuremode, load capacity, drift capacity and structural columns at the ends of wall, etc, quasi-static tests of two wallswith opening were conducted. The test results indicated that shear failure occurred on both sides of wall piers nearthe opening and diagonal cracks occurred on walls at the bottom of opening but width was not large. The lateralload-displacement hysteretic loops for the wall with structural columns were plump compared to that without struc-tural columns, nominal yield load and peak load increased about 20% and 30%, stiffness degradation is relativelyslow. The value of drift ratio was 1/90 for the two specimens, which can satisfy the requirement for shear wall un-der severe earthquake.
