摘要
为研究温度效应对大跨度混凝土结构受力的影响,结合某铁路特大桥实际工程,建立了混凝土箱梁的热-结构耦合分析三维有限元模型,分析了在温度场作用下混凝土箱梁的应力分布规律以及温度场变化对横向分析结果带来的影响。
To study the influence of temperature effect on the internal force of large-span concrete structure, a three-dimensional finite element model for thermal-structural coupling analysis of concretebox girder though the actual engineering of a railway bridge is established and the stress distribution laws of concrete box girder under action of temperature field and the influence of temperature field changes on the results of transverse analysis is discussed.
