摘    要：对全桥、横梁采用两次有限元离散计算方法，考虑桥面系、主桁架相互作用问题，研究了单线和双线钢桁梁桥的实际受力状态和设计者常采用的简化计算方法存在的问题，对《铁路桥跨结构设计规范》(初稿)中有关纵、横梁的计算条文提出了建议，它们对各类钢桁梁桥的设计均有参考价值。

Abstract: Using two step finite element method and allowing for the interact between the main truss and the floor system of the railway steel truss bridges, the actual stresses of the single-lined bridge and double-lined bridge, as well as the problems existing in the simple method often used by designers have been analyzed. The suggestions were put forward to the calculation of longitudinal and transverse beams in the“Railway Bridge Design Code”.
