为了分析讨论地下室侧向刚度对多高层框架结构的影响,本文首先建立了地下室楼层的侧向刚度与相邻上部楼层侧向刚度比(以下简称刚度比)从0.5~5.0变化时的分析模型.通过研究分析不同模型下结构的周期、位移及内力的变化,同时对比地下室顶板嵌固时的情况,得到刚度比的变化对结构特性的影响.然后考虑结构在大震作用下的Pushover分析,来进一步说明刚度比的变化对多高层框架结构的影响,从而得出相关结论.
為瞭分析討論地下室側嚮剛度對多高層框架結構的影響,本文首先建立瞭地下室樓層的側嚮剛度與相鄰上部樓層側嚮剛度比(以下簡稱剛度比)從0.5~5.0變化時的分析模型.通過研究分析不同模型下結構的週期、位移及內力的變化,同時對比地下室頂闆嵌固時的情況,得到剛度比的變化對結構特性的影響.然後攷慮結構在大震作用下的Pushover分析,來進一步說明剛度比的變化對多高層框架結構的影響,從而得齣相關結論.

The purpose of this paper is to study the influence of lateral stiffness of the basement on multi-story and high -rise frame structures.Models, of which the basement lateral stiffness varies from 0.5 to 5 times of that upstairs , were built up .Considering the embedding of basement roof , the differences of period , dis-placement and internal force between different models were studied .Furthermore , pushover study on frames of different stiffness ratios under strong earthquakes was performed to confirm their influence on structure parame -ters.
