摘要
以某异型景观斜拉桥为工程背景,采用有限元软件ANSYS建立有限元模型,研究独斜塔斜拉桥在塔底固结、有桩及改变桥梁结构参数三种情况下的动力特性,三者差别不大,建议采用无桩模型进行地震反应分析,结果表明该桥具有较好的抗震性能。
Taking a special-shaped landscape cable-stayed bridge with single slanted pylon as engineering background, a 3-D finite element model was established by the software ANSYS, and researching on the dynamic characteristics of the bridge, when there were no piles, piles in the bridge changed structure parameters of the bridge. There were little differences among the three situations. The first case was suggested to make the seismic response analysis. The results showed that the bridge has better seismic oerformance.
