摘要
在双层柱面网壳结构中引入预应力拉索,不仅能增大结构跨度,还能提高大跨度结构的安全性、稳定性.钢结构建筑的稳定性能是钢结构设计的关键因素.文中以大跨度双层柱面网壳结构为例,采用有限元法,选取四种对结构受力有利的布索形式,结合矢跨比、跨度、厚度等因素,对所选结构模型进行稳定性分析.
Abstract
The introduction of prestressed cables in double-layer cylindrical reticulated shell structure can not only improve the span of the structure,but also improve the safety and stability of large-span structures.The stability performance of steel structure building is the key factor of steel structure design.In this paper,taking the large-span double-layer cylindrical lattice shell structure as an example,using finite element method,select four kinds of cable arrangement forms which are beneficial to the structure.Combined with the factors such as rise-span ratio,span and thickness,the stability analysis of the selected structural model is carried out.
