摘要
为了探讨某大跨钢桁架拱桥的结构稳定性,采用有限元软件Midas/Civil建立桥梁空间仿真模型,针对不同荷载工况组合下结构展开弹性稳定分析,并探究了矢跨比、吊杆断裂和荷载布置形式对桥梁结构稳定性的影响。
In order to discuss a large span steel truss arch bridge structure stability, this paper establishes the simulation model of bridge space using the finite element software Midas/Civil elastic stability analysis for structure under different load combinations, and explores the influence of span ratio, fracture and load layout of the bridge structure stability.
