斜拉拱桥是一种新型组合桥梁,以湘潭市湘江四大桥为例,利用AN SY S软件建立了斜拉拱桥的三维空间有限元模型,对其振动频率及振型进行了分析,并讨论了主要结构参数对振动频率的影响,为斜拉拱桥的设计提供参考。
The cable-stayed arch bridge is a new type of composite bridge. Taking the Xiangjiang River Bridge No. 4 as an example, a three-dimensional finite element model of the cable-stayed bridge is established by AN SYS software. The vibration frequency and vibration mode are analyzed. The influence of main structural parameters on the vibration frequency is provided for the design of the cable-stayed bridge.
