摘　　要：由于强度、环保、施工方便等多方面的优势,混凝土空心砌块成为粘土砖的最理想的替代材料。不过砌块建筑经历的震害很少,抗震研究的成果也少。针对多层砌块建筑的抗震设计需求,模拟不同楼层压力,对15片1.4m×1.2m的空心混凝土砌块墙片进行了伪静力试验,得到了往复力-位移曲线,可供砌块结构抗震设计参考。Because of the advantages on strength, environment protecting and constructing convenience, concrete hollow block becomes the best substitute of clay brick. But the earthquake damage experiences and seismic research results are relatively less for this kind of material. This paper presents some results on the seismic behavior of wall elements of the concrete hollow block tested by quasi-static facility. Lateral force-displacement curves of the wall elements of the concrete hollow block under different vertical stress are obtained, and its limited lateral resistance is roughly equal to that suggested by the Code GBJ 50011-2001.
