【 摘 要 】

The paper presents a constructive solution for the metallic structure of a city railway bridge, with pedestrian area. The structure made of HEM beams has a modular design in order to facilitate the transport and in-situ assembling. The results obtained from static, dynamic and fatigue analyses are presented. Static analysis highlights areas with maximum stresses and displacements. Dynamic analysis aims to determine the own frequencies of the structure. Analysis of fatigue behaviour aims to compute the fatigue safety factors. The methodology presented in the paper is part of a unitary approach in the design of optimised bridge structures.
