[提要]  為探求將彈塑性地震反應(yīng)分析由構(gòu)件層次擴(kuò)展到結(jié)構(gòu)層次的可行途徑，提出了基于結(jié)構(gòu)振動(dòng)臺(tái)實(shí)驗(yàn)和墻體偽靜力實(shí)驗(yàn)的結(jié)果，建立結(jié)構(gòu)恢復(fù)力模型的骨架曲線。結(jié)合對(duì)砌體結(jié)構(gòu)滯回和剛度退化規(guī)律的已有研究成果，建立結(jié)構(gòu)恢復(fù)力模型，進(jìn)行結(jié)構(gòu)彈塑性地震反應(yīng)分析。分析結(jié)果得到實(shí)驗(yàn)的驗(yàn)證。說明這是一種在結(jié)構(gòu)層次進(jìn)行彈塑性地震反應(yīng)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.
