设计了汉口火车站无站台柱雨棚,着重阐述了其结构布置和受力体系.对结构在各种荷载工况下进行了计算分析.通过优化雨棚的拱轴曲线,得到了最合理的拱轴线,从而有效降低刚架梁截面高度.计算分析了温度作用对超长大跨度拱结构的影响,结果表明温度荷载对刚架和基础均产生较大内力.从特征值屈曲和非线性屈曲两个方面,对结构的整体稳定性进行了分析,分析表明大跨度拱结构具有良好的稳定性和承载能力. Designed the Hankow train station without platform canopy, focusing on the structure layout and stress system.The structure under various load conditions are calculated and analyzed by optimizing the canopy arch axis curve, the most reasonable Arch axis, so as to effectively reduce the cross-section height of the rigid frame beam.Calculation and analysis of the effect of temperature on the long and long span arch structure results show that the temperature load on the rigid frame and the foundation have a greater internal force from the eigenvalue buckling and nonlinear buckling In two aspects, the overall stability of the structure is analyzed, and the analysis shows that the long-span arch structure has good stability and carrying capacity.
