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.关键词
