正交异性钢桥面板纵肋与横肋连接构造细节

摘要

正交异性钢桥面板的纵肋与横肋连接是受力较复杂、病害较多构造部位。选取横肋腹板空孔、纵肋内隔板设置、纵肋与横肋间焊缝、横肋过焊孔等4个主要构造细节，从受力特性、病害及其治理、工程试验、加工工艺、各国规范发展等角度，系统地汇总正交异性钢桥面板纵肋与横肋连接构造的演变历程和发展现状，并总结经验教训。%The joints between longitudinal stiffeners and transverse stiffeners at orthotropic steel bridge deck are inclined to bear defects due to complex force influence. This paper outlines the development courses and the current status of four major parts in the joint structure-the empty hole on the web of transverse stiffener,arrangement of internal diaphragms between the longitudinal stiffeners,weld seams between longitudinal and transverse stiffeners,as well as the weld access hole on transverse stiffener-from the perspective of force influence, engineering experiments, processing techniques and its construction standards in different countries. At the same time,the paper also concludes the lessons from before for further study.
