摘要
正交异性钢桥面板是国内外大中跨径桥梁普遍采用的桥面结构形式,由于直接承受车轮荷载的反复作用,疲劳问题非常突出。详细阐述正交异性钢桥面板细节构造的疲劳研究概况和相关结论,简述钢桥面板的疲劳评估方法,并对正交异性钢桥面板的疲劳研究进行展望和建议。
Orthotropic steel bridge deck is a kind of bridge decks that is applied widely domestic and abroad, because of wheels loads repeated and direct, its fatigue problem becomes outstanding. The fatigue research general situation and related conclusions of detail configurations in orthotropic steel bridges are discussed particularly, and the fatigue evaluation methods are briefly described . Finally, expectations and suggestions for fatigue research on orthotropic steel decks are put forward.
