钢管混凝土拱组合梁渡槽结构静力分析

Structural Static Analysis of Steel Tube Concrete Arched Combined Beam Aqueduct

针对钢管混凝土拱组合梁渡槽复杂结构 ,建立了合理的有限元模型 ,编制了前后处理程序 ,并利用Sup 91程序对结构整体进行了计算和分析 ,给出了渡槽结构各构件在不同荷载组合情况下的应力、应变及其最大值所发生的部位 ,提出了结构尺寸调整的合理化建议 ,为工程设计单位提供了有价值的分析结果 ,为渡槽结构优化造型的初步设计提供依据 .

This article established a reasonable finite unit model, worked out the managingprogram before and after in allusion to the complicated structure of the steel tube concrete arched combined beam aqueduct, calculated and analyzed the structural mass by using SUP91 program, gave the stresses and strains of aqueduct structural member in different loads-combined, and gave the place of maximum stress and strain. It also put forward the rationalization proposal of adjustment of stuctural size, presented valuable results for the engineering design company, and provided foundation for the optimization of the model selection and primary design.
