| 摘 要： | 本文提出了由楼层地震反应记录反演有效地震输入的方法,并给出了考虑水平与摇摆耦合运动的土壤-结构相互作用体系有效输入的计算公式。文中还给出了简单的算例。计算结果表明:若将结构底层或地下室获得的地震反应记录作为结构地震反应分析的输入,与按有效输入所算得的结果相比有较大的差别,随着相互作用影响的增加,这种差别将越加明显。

| Abstract: | In this paper, a method for evaluation of the effective inputs based on theearthquake response records of floors is presented. The formula for evaluatingthe effective inputs of a soil-structure interaction system is derived when thecoupling between sliding and rocking is considered. Two simple examples aboutthe application of the formula are also given. The digital results show that thereexist significant differences between the results by using the base earthquakerecords and those by using the effective inputs, and this phenomenon becomes moreapparent when the effect of interaction is increasing. |
