斜拉拱桥抗震分析

Anti-seismic Analysis on Cable-stayed Arch Bridge

斜拉拱桥是的一种新型组合桥梁,以某已建成桥梁为例,利用ANSYS软件建立斜拉拱桥的三维空间有限元模型,对其抗震性能进行了分析,结果表明,在7度设防标准下,能满足规范要求。

Cable-stayed arch bridge is a kind of new combined bridge.Taking an established bridge as an example,it utilizes ANSYS software to establish three-dimensional space finite element model of cable-stayed arch bridge,and analysis is made on its anti-seismic performance.The result shows that,under 7-level fortification criterion,it can meet the criterion requirement.
