钢桥整体节点的疲劳性能研究

Research of the fatigue property of the steel bridge monolithic joints

指出对于钢桥,节点的疲劳破坏是最主要的破坏形式,以某大桥的整体节点为模型,采用疲劳试验分析和有限元计算的方法对其进行疲劳性能分析,结果表明,该桥梁的整体节点具有足够的抗疲劳强度。

It points out that regarding the steel bridge, the fatigue failure of the joints is the most main destruction form. In this paper, takes the monolithic joint of some bridge as a model, with the fatigue test analysis and the finite element computation, a weary performance analysis is carried on. The results show that the monolithic joint has a sufficient anti-fatigue.
