大跨度斜拉桥非线性地震反应分析

On the non-linear seismic response analysis of long-span and cable-stayed bridges

为了探索斜拉桥梁的整体受力性能,以徐州市和平路跨铁路站场斜拉桥主桥设计方案为具体的分析对象,选取结构在地震作用下的结构反应及受力性能进行研究,以期望对今后此类桥型的设计与施工能具有一定的指导意义。

In order to explore the whole stressed performance of the cable-stayed bridges, the paper takes the design scheme for the cablestayed bridge over railway in Heping road of Xuzhou as an example, and researches the structural response and the stressed performance under the earthquake effect, in order to exert its directive significance in the future design and construction of the similar bridges design.
