摘　　要：在试验数据与结果分析的基础上,得出高宽比与竖向压应力对AAC砌块墙体抗震抗剪强度影响较显著,同时比较已有的几种砌体抗剪强度计算公式,提出以主拉力理论为基础,考虑高宽比影响的无筋AAC砌块墙体抗震抗剪强度计算公式,该公式与试验结果吻合较好。通过分析表明:当高宽比对墙体的抗剪强度影响较大时,该公式具有较普遍使用意义。Based on the experimental data and and vertical pressing stresses have great influence shear strength formulas for block walls,a new shear analyses results, it is shown that height to width ratios on the AAC block wails. Then analyzing the several strength formula based on the theory of main pulling force is proposed, for unreinforced AAC block walls with considering height to width ratio. The results of caculation coincided well with the experimental data. It is concluded that the formula is propitious to the unreinforced AAC block walls with great influence of height to width ratio.
