摘要
矮塔斜拉、无背索斜拉等新颖的桥梁结构型式,在中等跨度的桥型中已占有较大竞争优势,成为许多业主欣赏的新桥型。结合工程实例,建立了空间有限元仿真模型,并且对模型进行了全桥结构动力分析,得到了该桥基本的动力特性参数,并对其进行了相应的动力反应谱分析,结果表明该桥抗震性能良好。
Nowadays,some new bridge structures such as low pylon cable-stayed bridge and no back-stays & inclined pylon cable-stayed bridge etc.By utilizing the spatial finite element method,the elaborate structural simulation model is set up Based on the project case and the dynamic analysis is conducted to the structure to get the dynamic characteristic parameters of this system.of response spectra analysis of the bridge and indicates a good seismic behavior of it.The result in the article will provide the design references for the project of no back-stays and extradosed cable-stayed bridge.
