随着我国钢结构事业的蓬勃发展,越来越多的空间结构体系在工程中得到应用。文中对大跨度管桁架屋盖体系结构采用的分析手段是建立在理论分析和实际工程紧密结合的基础上的,就主桁架的性能、制作方案、焊接工艺流程等方面进行了剖析,所得出的结论具有一定的指导意义和工程应用价值,也为进一步探讨空间钢管桁架结构体系提供了基础。
With the vigorous development of China’s steel structure, more and more space structure systems have been applied in engineering. In this paper, the analysis method adopted for the long-span pipe truss roof system is based on the close combination of theoretical analysis and practical engineering. The main truss’s performance, production scheme and welding process flow are analyzed. The conclusion has certain guiding significance and engineering application value, and also provides the foundation for further exploration of the spatial steel pipe truss structure system.
