摘要

为了研究波形钢腹板曲线T构桥的动力特性与地震响应,文章以四川某公路东河3号大桥为工程背景,建立动力有限元分析模型,采用多重里兹向量法进行了动力特性分析,并运用反应谱法计算了该桥在三向地震动作用下的地震内力响应,分析了主梁内力的变化规律、桥墩抗震能力,可供同类工程参考。
A dynamical finite element model is established in order to study the dynamic characteristics and seismic responses of single T-type rigid frame curved bridge with corrugated steel webs bsaed on the engineering background of Donghe No. 3 Bridge in Sichuan.The dynamic characteristics of this bridge are analyzed with the multiple Ritz vector method. The method of response spectrum analysis is used to calculate the seismic responses of the bridge under three-directional ground motions. The laws change of internal forces of main girder and the seismic capacity of the pier are also studied. It can offer a reference for the seismic analysis of the same type of bridges.
