摘要(Abstract):

对空透型屋架的外观要求,提出双向复式张弦梁这种新型大跨度空间结构形式,以浙江大学新校区图书信息中心门厅采光顶工程为例,阐明对零状态、初始态和荷载态的理解及相应计算分析方法与步骤;分析该结构在稳定、整体刚度、抗风能力等方面的特点;介绍关键节点构造与施工方法和进一步优化设计的构想。
A two-way compound beam string structure is proposed which is a new style of spatial structures,to meet the visual requirement of transparent roofs.Taking the natural lighting roof for the lobby of the library information center in the new campus of Zhejiang University as an example,we presents the method and procedures for the analysis and design of the structure based on the understanding of its three states.The behaviors of the structure,including the structural stability,integral stiffness,wind resistance and etc.,have been investigated and analyzed.Discuss on the further optimization of the structure is presented.And the fabrication for the key joints of the structure and the construction method used are described.
