摘　　要：对2组4片节能型砌体组合墙片进行低周反复加载试验来研究该结构的抗震变形能力,试验设计了2组不同高宽比(0.933、0.7)的1/2缩尺模型,试验结果表明:试验墙片的破坏主要为构造柱裂缝与砌体部分的裂缝相贯通并向对角方向发展,且墙体中间偏下段出现水平裂缝,伴有砌块脱落的现象;2组试件的极限位移角平均值为1/64;滞回曲线较饱满,表明节能型砌体组合墙片具有良好的抗震变形能力。A cyclic lateral loading test was made to study the seismic deformation ability of two group of four composite wall of energy-saving masonry.In the test,two groups of different height to width ratio （0.933,0.7） scale model were designed.The test results showed that the damage of test walls mainly was that the through crack of constructional column and masonry was communicated and expanded to diagonal direction.Meanwhile,the horizontal cracks appeared at middle part of wall with blocks fall out.The average ultimate displacement angle of two groups of specimens was 1/64,and the hysteresis curves were relatively full,which indicated that the composite wall of energy-saving masonry has good seismic deformation ability.
