摘　　要：通过6片AAC砌块承重墙体在低周反复荷载作用下的抗震试验，得出各墙体的滞回曲线和骨架曲线，主要研究了不同高宽比和不同竖向压应力对墙体滞回特性的影响。研究表明，高宽比可以影响墙体破坏的弹塑性阶段和破坏阶段，竖向压应力只能影响弹塑性阶段；高宽比较小和竖向压应力较大的墙体抗剪强度高．抗震性能好。Based on the seismic experiment of 6 AAC block walls under cyclic loading,hysteretic curves and skeleton curves are given.The hysteretic behavior of the walls due to different height to width ratios and vertical pressing stresses are mainly studied. The results indicate that ,the height to width ratios can affect elastic-plastic stage and plastic stage,while vertical pressing stresses can only affect elastic plastic stage; the walls with small height to width ratios and large vertical pressing stresses possess higher shear strength and better seismic behavior.
