摘　　要：为研究沙漠砂蒸压加气混凝土砌块砌体恢复力模型,对10片采用低周反复加载方式的试件的试验现象及数据进行分析。基于试验结果和现有恢复力模型理论,采用三折线模型对沙漠砂蒸压加气混凝土砌块砌体的荷载位移曲线进行回归分析,建立了沙漠砂蒸压加气混凝土砌块砌体的恢复力模型,并确定了相应的滞回规则。结果表明:三折线恢复力模型与试验结果吻合较好,能够较好地反应沙漠砂蒸压加气混凝土砌块砌体的恢复力特性,其成果可为该结构在新疆村镇建筑抗震分析提供技术支撑。In order to study the restoring force model of desert sand autoclaved aerated concrete block masonry,the experimental phenomena and data of 10 specimens under low cyclic loading were analyzed.Based on the test results and the existing restoring force model theory,the regression analysis of the load displacement curve of the desert sand autoclaved aerated concrete block masonry is carried out by using the three-fold line model.The restoring force model of the desert sand autoclaved aerated concrete block masonry is established,and the corresponding hysteresis rules are determined.The results show that the three-fold line restoring force model is in good agreement with the test results,which can better reflect the restoring force characteristics of the desert sand autoclaved aerated concrete block masonry.The results can provide technical support for the seismic analysis of the structure in Xinjiang villages and towns.
