下承式钢箱系杆拱桥局部结构有限元分析

The Finite Element Analysis of Local Structure of the Through Steel-box for Tie-bar Arch-bridge

吊杆与钢箱拱肋锚固连接处是下承式钢箱系杆拱桥受力的关键部位。针对正在设计中的重庆市江津区滨州路工程的下承式钢箱系杆拱桥,采用大型通用有限元软件ANSYS,对其吊杆锚固结构进行局部受力分析,并对分析结果进行了对比和综合评价,结合分析提出了一些观点。

The anchor junction of Suspender and Steel box arch rib is a key component of the force.Aiming at the through steel-box tie-bar arch-bridge being designed in BinZhou Road Project,JiangJin,ChongQing,this paper analyzes the stress distribution of the suspender anchor structure by using large common software ANSYS,and the results of analysis are compared and evaluated,and some viewpoints are put forward based on the analysis.
