摘要
为了研究干垒式灌孔混凝土砌块灌芯砌体在轴压荷载下的荷载分配及变形情况,进行12个干垒式混凝土砌块灌芯砌体的基本力学性能试验。试验结果表明,提高灌芯混凝土强度能够增大整个砌块砌体的弹性模量,灌芯混凝土承担此类砌体承受的大部分荷载。基于试验数据和规范给出了干垒式混凝土砌块灌芯砌体弹性模量和抗压强度的理论计算公式。
To study the load distribution and deformation of dry-stacked grouted-concrete block masonry under axial compression,the mechanical properties tests on twelve block masonry specimens with two kind of grouted concrete are carried out.The results show that the increase of strength of grouted-concrete could improve the elastic modulus of block masonry,and most of the compressive load is shared by concrete core.Based on experimental data and the code for design of masonry structure,theoretical formula for the elastic modulus and compressive strength of dry-stacked piece grouted-concrete block masonry is given.
