大跨屋盖结构设计研究——以第十届全国大学生结构设计竞赛为例

Research on the Design of Large-span Roof Structure——Taking the 10th National College Students' Structural Design Competition as an Example

大跨度空间结构广泛应用于大型体育场馆、航站楼等高标准建筑设计。依照第十届全国大学生结构设计竞赛的命题,从结构选型分析、截面设计及制作工艺三个方面,介绍了长沙理工大学参赛作品的设计与制作过程,并创新性地提出结构设计的预应力思想,认为将模型制作的铰接转化为刚接的方法,有利于结构的优化设计。

Large-span space structure is widely used in large-scale stadiums,terminal buildings,and other high-standard architectural design. According to the proposition of the 10 th National College Students structural design competition,this paper introduced the design and production process of the competition model of Changsha University of Science and Technology in the aspects of structural selection analysis,cross section design,and production process. Futhermore,it put forward the prestressing idea of structural design creatively,and recomanded the method of transformation between hinge and rigidity connection,which are beneficial to the optimal design of the structure.
