摘要
采用销键使混凝土小型空心砌块相互咬合,可以有效地提高砌体结构的抗剪强度,改善砌体结构的抗震性能,是一种新型的砌体结构。通过对这种新型砌体结构的单面和双面剪切试验,分析了新型砌体结构的剪切变形过程,与普通砌体结构进行了对比,提出了此新型抗震砌体结构的抗剪强度计算方法。
By inserting a concrete bolt in the hole can chain the upper block with lower block,the shear sterngth of the small hollow concrete block masonry can be increased effectively and seismic performance improved.This is a new type of masonry structure.150 new small-sized hollow concrete block masonries are compared with 150 normal small-sized hollow concrete block masonries under 5 different axial loads in this experiment to test their shear resistance.The shear deformation process was analyzed and its shear capability formula obtained.
