为确保钢桁架桥梁的安全运行,采用空间结构有限元分析软件Midas Civil对桥梁结构进行计算,重点分析了在各种荷载组合工况作用下结构的变形、应力分布、支座受力情况、结构稳定性及动力特性,为类似工程设计提供一定借鉴。 In order to ensure the safe operation of the steel truss bridge, the finite element analysis software Midas Civil is used to calculate the structure of the bridge. The deformation, stress distribution, bearing force and structure of the structure under various load combination conditions are analyzed. Stability and dynamic characteristics, to provide some reference for similar engineering design.
