摘要
介绍正交异性钢桥面板的发展历史和正交异性钢桥面板疲劳问题的产生原因和分析方法,以及国内外研究现状.阐述疲劳分析的基本概念和理论,分析疲劳裂纹的成因以及研究方法.总结美国的AASHTO规范、英国的BS5400规范、欧洲的Eurocode规范和日本规范中关于疲劳荷载谱的研究成果.在对国内外研究成果加以整理的基础上,建立了一个符合我国实际情况的疲劳车模型.
The paper introduces the development history of orthotropie steel bridge deck analyses the causes of fatigue, and the status quo home and abroad. It describes the basic concepts and theories about fatigue analysis, and summarizes the research of fatigue load spectrum embodied in America AASHTO specifications, UK BS5400 criterions, Europe Eurocode standards and Japan norms. On the basis of the research and analyses home and abroad, a truck model is established to meet domestic conditions.
