摘要为了研究高延性混凝土（HDC）加固震损古旧砌体的抗震性能，对6个HDC加固震损古旧砌体试件进行低周反复荷载试验，研究HDC加固面层总面积、砌筑砂浆强度、试件开洞口数量等因素对各试件的破坏特征、滞回曲线等抗震性能指标的影响程度。试验结果表明，用HDC加固后古旧砌体的峰值荷载较加固前最大提升可达313.4%，延性位移系数较加固前最大提升可达151.3%。在试验基础上，通过确定骨架曲线恢复力模型、卸载刚度退化规律并结合加卸载滞回规则，建立适合HDC加固震损古旧砌体结构的三折线恢复力模型。所得到的计算曲线与试验曲线吻合度较好，该三折线恢复力模型可用于地震作用下HDC加固震损古旧砌体的非线性动力反应分析。

Abstract：In order to study the seismic performance of high ductile concrete (HDC) reinforced seismically damaged and ancient masonry, six the seismically damaged and ancient masonry specimens strengthened by HDC were tested under low cyclic loading, the influence of factors such as the total area of HDC reinforced surface, the strength of masonry mortar and the number of openings on the seismic performance indexes such as failure characteristic and hysteretic curves were studied. The test results show that the peak load of the ancient masonry strengthened with HDC can be increased by 313.4% and the ductility displacement coefficient can be increased by 151.3%. On this basis, considering the mechanical characteristics of ancient masonry specimens, the skeleton curve model, stiffness degradation rules and loading and unloading rules are obtained, and a three-linear restoring force model suitable for HDC strengthening ancient masonry structures is established. The results show that the restoring force model can reflect the relationship between load and displacement of ancient masonry structure strengthened by HDC under low cyclic loading. The three-linear restoring force model can be used for nonlinear analysis of ancient masonry strengthened by HDC under earthquake action.

Key words： high ductile concrete (HDC) seismic damaged and ancient masonry seismic reinforcement hysteretic curve three-linear restoring force model
