[摘要]  通过烧结普通砖砌体与混凝土空心砌块砌体的抗震抗剪强度的试验方法和试验结果的对比分析，得出了现行抗震规范中采用的混凝土空心砌块砌体的抗震抗剪强度取值偏于不安全的结论，并结合国内58片墙体试验结果进行了统计分析，提出了较为合理的设计计算公式。

Abstract:  Through the comparative analysis of the experimental method and result about the seismic shear strength of fired common brick masonry and concrete hollow block masonry, it was found that the formula of the seismic shear strength of hollow concrete block masonry in Code for seismic design of building (GB50011 -2001)  is not safe enough. Statistical analysis about 58 walls experimental result has been carried out. Finally, a reasonable seismic shear strength formula for concrete hollow block masonry is proposed.
