摘要
结合较大屋面荷载下的大跨钢结构建筑项目实例,以建筑功能性、结构可靠性及设计经济性为前提,对比了不同桁架形式各自的优劣。同时,介绍了温度应力的影响以及桁架支座的应力计算。总结的设计经验可为类似的大跨结构项目中钢屋盖的选型和计算提供借鉴。
Combined with the large-span steel structure construction project under large roof load,the advantages and disadvantages of different truss forms are compared on the premise of building functionality,structural reliability and design economy.At the same time,the influence of temperature stress and the stress calculation of truss support are introduced.The summarized design experience can provide reference for the selection and calculation of steel roof in similar large-span structure projects.
