【摘要】 以闵浦二桥为工程背景,运用大型有限元软件MIDAS/Civil,建立了上海闵浦二桥的有限元计算模型,对此桥进行动力特性分析,并详细介绍动力反应谱法,用此法对上海闵浦二桥进行了地震反应谱分析,利用CQC振型组合方法,分别进行两个最不利组合下的地震反应谱分析。更多还原

【Abstract】 This paper used large finite element software MIDAS /Civil do anti-seismic analysis of Minpu Bridge II,and did the dynamic characteristics analysis of the bridge,and introduces the dynamic response spectrum method. Response spectrum method and CQC modal combination method were taken for the anti-seismic analysis. Two of the most unfavorable combinations were considered.更多还原
