【摘要】 本文采用SAP2000有限元分析软件,对基础滑移隔震结构分别进行水平单向和双向的EI-centro地震波输入,分析结构的地震反应。结果表明,当考虑双向水平地震作用时,基础滑移隔震结构的支座位移明显增大,上部结构的层间位移比较小且无明显变化,加速度虽变小但是变化幅度也比较小。因此,在实际工程应用中应该考虑双向水平地震作用对支座位移的影响。更多还原

【Abstract】 This article analyzes the response of structure with sliding base-isolation by SAP2000 finite element software,while inputing horizontal unidirectional and bidirectional seismic wave respectively.The results indicate that,when considering bi-directional horizontal seismic action,the displacement of support increases obviously,the displacement between layers and acceleration has no obvious change,the acceleration decreases a little.Therefore,bi-directional horizontal seismic action effects on the displacement of support should be taking into consideration in the practical application.更多还原
