摘　　要：为编制低层装配式墙体在一种新型水平连接形式下抗剪承载力计算规范,对51个预制墙体进行了不同条件的试验研究,对其中的15个纯砂浆连接墙体抗剪承载力及破坏形态进行了分析。研究表明,纯坐浆连接墙体受剪破坏具有明显的脆性破坏特征;轴压比的增加,引起砂浆层上下界面摩擦力的增大,导致抗剪承载力的提高;接地梁上表面与墙板下表面粗糙度对试件抗剪承载力有重要影响。最后,通过试验结果推导出了现有文献中承载力计算的相关参数,该计算式将为设有边缘构件的墙体承载力计算提供相关理论依据。In order to compile a calculation standard for the horizontal shear capacity of the low-rise assembled wall under a new horizontal connection form,the research team carried out different conditions on 51 walls,and the paper sheared 15 of them.The results show that the shear failure of grouted wall has brittle failure characteristics;the shear bearing capacity increases with the increase of axial compression ratio;the roughness of the upper surface of grounded beam and the lower surface of wall plate have an important influence on the shear bearing capacity of specimens.Finally,based on the test results,the relevant parameters of bearing capacity calculation in the existing literature are deduced.The formula will provide a theoretical basis for the calculation of the bearing capacity of walls with edge members.
