摘　　要：本文收集了国内大量的混凝土小型空心砌块墙片试验资料,通过研究芯柱-构造柱混凝土小型空心砌块组合砌体受力特征及影响抗震剪切承载力的主要因素,结合理论计算分析,提出了抗震剪切承载力的通用计算公式。该公式既适用于芯柱-构造柱混凝土小砌块墙体,又适用于只设置芯柱或构造柱砌块墙体结构。通过试验值与计算值的比较,证明本文所提出通用公式的准确性。The strength and deformation characteristics of small hollow concrete block walls with core columns and constructional columns are studied and the effect of main factors on the seismic shear strength of such walls is described in this paper. From the statistic analysis of a great number of collected test data of such walls a general formula for estimation of the seismic shear strength of concrete block walls with core columns and constructional columns is suggested. The formula is also applicable for masonry walls with only core columns or only constructional columns. The applicability of the formula is verified by comparison between results of test and computation.
