虚拟随机激励法及其应用研究

摘要

The paper indicates the common seismic calculation method, establishes the dynamic calculation model according to the introduction of the pseudo-excitation method, analyzes the random vibration of the leaning arch bridge, and points out the concept is identified and its meth-ods are simple by solving the structural dynamic response with the pseudo excitation method.%简述了常用的地震验算方法，通过对虚拟随机激励法的介绍，建立了动力计算模型，并对斜靠式拱桥随机振动进行了分析，指出虚拟激励法求解结构动力响应，概念明确，方法简单。
