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

Embodiment Construction
[0018] like figure 1 , figure 2 , image 3 , Figure 4 As shown, a rib-ring type cross-cable reticulated shell structure in which the load-bearing cables are arranged crosswise, the structure includes a rib-ring type single-layer reticulated shell 1 , a load-bearing cable 3 , a strut 2 and a lower support 4 .
[0019] The rib-ring cross-cable reticulated shell structure is an annular structure with a large central opening; the upper part of the rib-ring cross-cable reticulated shell structure comprises a rib-ring single-layer reticulated shell 1 , a load-bearing cable 3 , and a strut 2 ; The two ends of each cable in the load-bearing cable 3 are connected to the different outermost ring joints of the rib-ring type single-layer reticulated shell 1, and each load-bearing cable 3 is symmetrically distributed with the center of the ring as the center and crosses each other in sequence; Each cross position of the load-bearing cable 3 is provided with a strut 2, the upper end of...

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 type crossed cable-supported reticulated shell structure with cross-arranged load-bearing cables. 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. Large-scale events such as the Beijing Olympics, the Shanghai World Expo, and the Guangzhou Asian Games have resulted in a large number of venues being built or renovated, which has further driven the innovation of the large-span spatial structure system. Large-span space buildings are often landmark buildings in a region, so not only should safety and economy be the goals of structural design, but more importantly, the beauty o...
