摘要
介绍了整体钢桥面板的受力三体系,并在介绍各国规范关于钢桥面板有效宽度的规定基础上,推导了由于考虑钢桥面板有效宽度所引起的截面特性的公式,这对于利用空间杆系模型计算桥面杆系应力是有益的。
Three systems of stress of the whole steel bridge deck are introduced. On the basis of introducing the provisions of standards of all countries on effective width of steel bridge deck, the formula of sectional properties caused by effective width of steel bridge deck is derived, which is beneficial to the calculation of trussing stress of bridge deck by utilizing space truss model.
