摘要
在研究大量资料文献的基础上,结合空间有限元分析,对比各种管节点疲劳检算方法的优缺点,研究了空心管节点疲劳检算方法在填心钢管-空心钢管节点疲劳性能分析中的适用性,对我国某在建大跨度铁路钢管混凝土拱桥(Y桥)拱肋管节点的疲劳性能作了可靠的分析评估,根据分析结果对该桥拱肋管节点的疲劳设计提出了合理建议。
On the basis of literature,the author investigated the applicability of the fatigue inspection method of hollow tube joints in the fatigue performance analysis of filled-hollow steel tube joints,made an evaluation on the fatigue performance of the joints of the arch rib of Y bridge,which is a certain big span railway CFST bridge in construction.According to the analyzing results,the author put forward reasonable suggestion for the fatigue design of the arch rib joints of Y bridge.
