摘要
结合施州大桥的工程设计实例,采用大型有限元分析程序AN SY S,选取空间BEAM 188和L INK 10单元建立有限元模型,研究了独塔单索面斜拉桥的动力特性.根据桥址场地地震参数,分别用反应谱法和时程分析法作斜拉桥的地震反应分析,得出了重要截面在地震作用下的内力和位移,并对抗震设计提出了一定的建议.
An engineering design case about Shizhou Bridge is investigated,using the FEA program ANSYS.Element Beam188,element Link10 are used in the FEM.The dynamics characteristics of single pylon partial one-side cable-stayed bridge are analyzed.According to the earthquake dynamic parameters of the bridge site,the earthquake response of Shizhou Bridge is analyzed using the earthquake response spectrum method and the time history analytical method.Internal force and displacement response of important sections in different load case are given.Finally,some advices about aseismatic design of the bridge is given.
