on the basic of classsifying and analysing the probable supporting structures of glass roof, new-type beam string structure using in long-span glass roof is brought forward and the thought and schemes of improvement are advanced 在对可能用于采光顶的支承结构进行分类与分析其特点的基础上,提出了适用于大跨度玻璃采光顶的新型张弦梁结构体系,并给出了从一般张弦梁到新型张弦梁的改进过思路及方案。
the addition of agi does n't change the short-range structure of glass network, the basic structural units forming the backbone of the network are ges4 / 2 and gas4 / 2 tetrahedral which are interconnected by bridging sulfurs to form a disordered three-dimensional network, agl disperse in it as network modifier agi的加入并未改变网络形成体的近程结构,[ges_4]和[gas_4]四面体通过桥s连接形成三维无序网络状结构,agi作为网络修饰体分布于其中。
the paper has disgussed the methods of strengthing space structure and glass roofs stiffenss . then has analyzed the rationality of supporting structure of glass roof . according as the existing nodes, new nodes have been given . resisting sllippage is tested simply, node conformation has been amended 论文从结构力学位移计算公式出发,讨论了提高空间结构刚度的有效途径,并提出增强采光顶支承结构刚度的措施,进一步分析了新型采光顶支承结构的合理性。
