A rib-ring cross-cable-supported reticulated shell structure with load-bearing cables intersecting

Abstract

The invention relates to a ribbed-type crossed cable supported lattice shell structure with bearing cable crossed layout. The structure comprises a ribbed-type single layer lattice shell, bearing cables, a supporting rod and a lower-portion support. The ribbed-type crossed cable supported lattice shell structure is an annular structure with a large central opening. The upper portion of the ribbed-type crossed cable supported lattice shell structure comprising the ribbed-type single layer lattice shell, the bearing cables and the supporting rod is supported through the lower-portion support. Cables of the supporting cable operate together coordinately; when partial bearing cables are broken, progressive collapse can be prevented from occurring effectively, and safety of constructive structure is guaranteed; each bearing cable is crossed mutually and supplies out-surface binding force to each other, out-surface stability can be maintained mutually, additional out-surface binding components can be omitted, steel material is saved, and bearing force is increased.

Description

technical field [0001] The invention relates to the field of large-span cable-supported reticulated shell roof structures, in particular to a rib-ring crossed cable-supported reticulated shell structure in which load-bearing cables are arranged crosswise. Background technique [0002] With the continuous progress of socialist modernization, social life has improved significantly, and the demand for large-scale public activity spaces such as stadium buildings, convention and exhibition center buildings, and traffic station buildings is increasing day by day. The holding of large-scale events such as the Beijing Olympic Games, Shanghai World Expo, and Guangzhou Asian Games has resulted in the construction or expansion of a large number of stadium buildings, which further drives the innovation of long-span spatial structure systems. A large-span space building is often a landmark building in a region. Therefore, it is not only necessary to take safety and economy as the goals o...

Problems solved by technology

Relevant studies have shown that the ring cable is an obvious sensitive component. When the ring cable is partially broken, it will lead to prestress relaxation of all the cables and struts connected to the ring cable. The supporting cable system cannot provide sufficient bearing capacity for the structure. The stiffness drops significantly, even leading to the overall collapse of the structure
