摘　　要：连锁式混凝土小型空心砌块砌体是一种新型的砌块砌体,通过在砌块的孔洞中插入T形键,能够有效提高砌体的抗剪强度,改善砌体结构的抗震性能。通过不同正压力下137片连锁式混凝土小型空心砌块砌体和137片普通混凝土小型空心砌块砌体的抗剪试验,分析和验证破坏机理,得出连锁式混凝土小型空心砌块砌体的抗剪承载力计算公式。This is a new type of block masonry. By inserting T-shape concrete bolt in the hole, its shear strength can be increased effectively and seismic performance improved. 137 chained small hollow concrete block masonries were tested under different vertical loads in comparison with 137 common ones. Failure mechanism was analyzed and verified and its shear strength formula obtained.
