【摘要】 本文建立了基于MIDAS商用软件的FRP桁架桥在吊装施工过程中的力学有限元模型,选择了三种吊装的工况进行了桁架的受力性能分析,根据分析得出的桁架桥不同工况下构件的形变、应力、支反力等结果,优化并得到了合理的施工方案,为FRP桁架桥的施工过程管理提供了技术支持。更多还原

【Abstract】 The article was established on mechanics finite element model in the process of hoisting construction,which is based on FRP truss bridge of commercial software MIDAS. And I selected three kinds of lifting operation conditions to analysis the stress performances of truss.According to the analysis of reactions of deformation,stress,bearing reaction of the truss bridge under different kinds of working condition,etc.,a reasonable construction scheme was updated and decided,which is providing a technical support for the construction process management of FRP truss bridge.更多还原
