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.
Aiming at the zigzag-shaped roof of Student Activity Center of Zhejiang University of Science and Technology, three different structural designs of rectangular steel tube single-layer folded reticulated shell, primary and secondary truss and double-layer grid + local single-layer reticulated shell are proposed respectively. From the angle of reasonable structure, professional coordination, ease of construction and meeting the needs of the owners, the structural scheme comparison and optimization of the complex foldable roof are comprehensively carried out. The aim is to obtain a structure that can fully reflect the mechanical properties and advantages of the structure, the optimal economic benefits , And meet the architectural form of visual and aesthetic requirements of space.This study can provide the basis for the preliminary design and multi-program comparison of the complex folding roof structure.
