摘　　要：为了研究在８度地震区建造小型混凝土空心砌块九层房屋的可行性，提出了一种新的结构体系──构造柱与芯柱组合的承重体系，并对一幢按１／４缩尺比例建造的九层房屋模型进行了水平反复加载静力试验和振动台激振试验，获得了模型房屋在水平荷载作用下整体受力的抗力特性和破坏形态以及在基础激振作用下的动力反应与倒塌机制。试验研究结果表明：（１）采用芯柱与构造柱结合的小型混凝土空心砌块体系在８度地震区建造九层房屋是完全可行的。（２）构造柱、芯柱小型混凝土空心砌块结构体系的抗震性能明显优于仅设芯柱的小型混凝土空心砌块结构体系。In order to study the possibility of constructing nine-story masonry building with concrete block in seismic regions of intensity Ⅷ, a new bearing wall system of small-size hollow concrete blocks, with installed tie columns and grouted reinforced cores, was proposed and a 1/4 scale model was built. The circlic static load test and shacking table test were carried out. Some results, such as earthquake-resistance capacity and collapse mode of the test model, are obtained. The test results show that the concrete block masonry buildings with installed tie columns and grouted reinforced cores have good seismic performance and the construction of nine-story concrete block masonry buildings in the regions of intersity Ⅷ is quite feasible.
