针对震损框架结构的整体抗震加固需求，提出一种将 RC(钢筋混凝土)-加气混凝土砌块组合墙嵌入震损框架内部实现抗震加固的方法，通过模型试验探讨该加固方法的可行性． 首先进行 1∶ 2 比例混凝土框架试件的预损试验，试件加载至大震损坏状态，然后将组合墙嵌入震损框架内部实现加固，再次进行加固框架试件的抗震性能试验． 根据试验结果，分析了原框架、震损加固框架的破坏过程和滞回曲线特点，对比研究了两者在承载力、刚度、变形能力等方面的相同及差异之处． 结果表明:对于大震震损框架，组合墙加固后其整体承载力与原框架基本一致或略有提高，屈服及极限阶段的等效抗侧刚度、耗能能力大于原框架，破坏阶段其变形能力及耗能略差于原框架． 试验初步证明了组合墙加固震损框架是一种可行的加固方法．

In order to meet the overall seismic strengthening requirements of seismic damage frame structures,a new strengthening method of embedding the RC (Reinforced Concrete)-aerated concrete block wall into the frame structure was proposed,and the feasibility of the proposed method was discussed by a model test.First,one 1∶ 2 scale concrete frame specimen was pre-damaged to a large earthquake damage state.Then,by embedding the com- posite wall into the frame structure,the reinforcement work was completed.Finally,a seismic performance test was conducted on the specimen again.According to the experimental results,the original frame and the seismic damage-reinforced frame are analyzed in terms of the failure process and the hysteresis curve characteristics,and are compared in terms of the bearing capacity,the stiffness and the deformation capacities.The results show that,as compared with the original frame,the bearing capacity of large earthquake damage frames strengthened with aer- ated concrete block composite walls is almost the same or even slightly improved,with greater equivalent lateral stiffness and energy dissipation capacity in the yield and the ultimate stages as well as with slightly worse deforma- tion capacity and energy dissipation in the destruction stage,which means that the proposed method is possibly feasible.
