浙江科技学院学生活动中心屋盖结构方案设计

Roof structure scheme design of Zhejiang University of Science & Technology Student Activity Center

针对浙江科技学院学生活动中心的折面形屋盖,分别提出了矩形钢管单层折面网壳、主次桁架和双层网架+局部单层网壳等三种不同的结构设计方案.本文从结构合理、专业协调、便于施工并满足业主需求等角度全面进行了复杂折面屋盖的结构方案比较及优化,力求获得一种能充分体现结构的力学性态和优势、最优的经济效益,并满足建筑的空间视觉与美观要求的结构形式.本文研究可为复杂折面形屋盖结构的初步设计与多方案比较提供依据.

This article introduces three types of large-span roof structures designed for the Zhejiang University of Science Technology Student Activity Center,which include：（1）the single-layer foldedplane reticulated shell,（2）the primary and secondary truss system and（3）the combined double-layer space grids and single-layer reticulated shell.Comparisons and selections are conducted between different types in consideration of structural performance,convenience of installation and the demand of the investor and architect.The study aims at providing the most optimized structure scheme with good mechanical property,economic benefit as well as satisfaction of architectural desire.The discussions and results in this article can be referenced for the preliminary design and scheme selection of complex folded-plane roof structures in succeeding projects.
