摘要
大连福佳大化泊位桥为8万t级码头栈桥,栈桥由两跨空腹桁架拱式钢桥组成,此类桥型结构受力兼有系杆拱桥和桁架桥的受力特性。通过大型有限元软件对其整体线性和非线性稳定进行了分析,研究结果表明该桥稳定性能够满足工程需要。
The 80 000-ton pier trestle located in Dalian is made up of tow span of arched vierendeel truss bridge.The structural performance of bridge is similar to a tied-arch bridge,and it performs like a truss bridge.Based on the geometric and material nonlinearity of structure,the three dimension stability analysis of the bridge is performed on the base of the numerical analysis,and comparison of the linear and nonlinear results is done.The analysis results show that the stability of the bridge is content to the specification.
