摘要
该文首先对目前国内外公路、铁路钢桥设计规范的疲劳设计方法和疲劳荷载谱予以回顾。针对正交异性桥面板钢箱梁疲劳受力特点分析了疲劳设计应注意的问题,并将我国焊接桥在发展过程中的主要疲劳研究成果作了概述。最后提出正交异性桥面板钢箱梁疲劳设计亟待解决的问题,提供给钢结构同行参考。
The article reviews the fatigue design method and the fatigue load spectrum in the design standards of the steel bridges for highways and railway at home and abroad,analyzes the issues for attention in the fatigue design aiming at the fatigue stress characteristics of orthotropic deck steel box beam,describes the main fatigue studying result in the development of the welded bridges in China, and puts forward the problems to be solved in the fatigue design of orthotropic deck steel box beam able to provide the reference for the similar steel structures.
