抚顺永安桥的动力性能分析
|
摘要
利用ANSYS对抚顺永安斜拉桥进行模态分析,得到了该桥的动力特性。采用标准反应谱作为输入的谱曲线, 分别考虑了纵向、横向、竖向输入下该桥的地震响应,分析了其抗震性能。计算结果表明,本桥的抗震能力是有保证的。
The paper studied the earthquake response of the Yong-an Bridge in Fushun City a concrete cable-stayed bridge with three towers and single cable plane with modal analysis of the bridge with ANSYS and the dynamic performances were obtained. The standard seismic response spectrum was used as input taking into account of longitudinal, transverse and vertical direction responses respectively. The seismic resistant capacity of this bridge was analyzed.It is indicated that the seismic resistant capacity of this bridge is ensured.
