[提要]  为探求将弹塑性地震反应分析由构件层次扩展到结构层次的可行途径，提出了基于结构振动台实验和墙体伪静力实验的结果，建立结构恢复力模型的骨架曲线。结合对砌体结构滞回和刚度退化规律的已有研究成果，建立结构恢复力模型，进行结构弹塑性地震反应分析。分析结果得到实验的验证。说明这是一种在结构层次进行弹塑性地震反应分析的可行方法。

For the purpose that we can use the elastic-plastic method to analyse a structure seismic response and not just to be limited in members, amethod is pointed out to develop restoring force model based on the results of shaking table experiment and pseudo-static experiment. We use the restoring force model to analyse a small concrete structure's response in earthquake. Then compared with the results of shaking table experiment of the structure, the analysis results is concordance with them, wluch indicates the method presented here is correct.
