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。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 bidirectional 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.
