摘要
为给我国公路桥梁正交异性钢桥面板抗疲劳设计提供参考,从疲劳荷载、疲劳细部分类及疲劳验算公式等方面对比AASHTO、Eurocode 3规范,并分别应用2本规范对我国一座公路桥梁的正交异性钢桥面板进行疲劳验算。结果表明:针对公路桥梁正交异性钢桥面板的抗疲劳设计,AASHTO、Eurocode 3两本规范在设计思路、细部分类、验算公式等方面基本一致,参考其对我国公路桥梁正交异性钢桥面板进行抗疲劳设计是可靠的,鉴于Eurocode 3对正交异性钢桥面板的疲劳细部规定更全面,参考Eurocode 3对公路桥梁正交异性钢桥面板进行抗疲劳设计较为合适。
In order to provide references to the anti-fatigue design of orthotropic steel bridge deck for highway bridges in China, the AASHTO and Eurocode 3 were compared from aspects of fatigue load, fatigue detail classification and fatigue checking formula, and the two codes were re- spectively consulted to carry out fatigue checking calculation for orthotropic steel bridge deck of a highway bridge in China. The results of the comparison and analysis indicate that in respect of the anti-fatigue design of the orthotropic steel bridge deck of highway bridges, the AASHTO and Eurocode 3 are basically consistent in terms of design idea, detail classification and checking for- mula, which can be taken as reliable references for the anti-fatigue design of orthotropic steel bridge deck for highway bridges in China. However, it is proper to take Eurocode 3 as the refer- ence in the anti-fatigue design of orthotropic steel bridge deck of highway bridges, considering its complete coverage for the fatigue details of orthotropic steel bridge deck.
