摘要
本文通过以天津永和桥为原型建立的综合考虑各结构细节力学特点的斜拉桥动力分析模型，利用大型结构分析程序ＭＳＣ／ＮＡＳＴＲＡＮ，对斜拉桥地震反应的空间特性、行波效应、非线性特性等进行了分析与讨论，得到了斜拉桥独特的地震反应特性。
A complete bridge model with reference to Tianjing Yonghe cable-stayed bridge is established for seismic analyis. Advanced finite element analysis program MSC/NASTRAN is success fully used here vn the sfudy of the the travelling wave effects as well as the nonlinearity effectsinvolved in the seismic behavior of cable-stayed bridges.The earthquake response characteristics of cable-stayed bridges are thus obtained.
