摘要
对上承式钢桁梁桥进行三维空间结构分析，从静力及动力特性两方面对桥门架及中间横向联结系的设置状况对上承式钢桁梁桥刚度的影响作了较详细的研究。
In this paper,the influence of installation case of portal frame and sway bracing on the stiffness of steel-truss deck bridges is analysed fully both from static and dynamic characteristics respectively by three dimensional analysis of the structure,and the results achieved may provide reference for the relevant designs.
