摘要
本文对全桥、横梁采用分步有限元离散计算方法，考虑桥面系、主桁架相互作用问题，研究了单线铁路钢桁梁桥纵、横梁的实际受力状态和设计者通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．
Using finite element method and allowing for the interaction between the main trusses and the floor system of the railroad truss bridge, the authors analyze the actual response of the stringers and floor beams of the 64 metre span truss bridge in two load cases. The results are compared with the traditionally simplified ones. Finally, the authors make some suggestions to the relevant items of the new Chinese n Railroad Bridge Designing Code'. (draft)
