The invention relates to an asymmetric large-span spoke type cable-supported space structure. The cable-supported space structure comprises asymmetric spoke type radial arc-shaped upper chords, asymmetric spoke type lower chord radial cables, ring trusses and outer ring beams, wherein the ring trusses comprise ring truss lower chord ring cables, inner ring beams and ring truss vertical web members, the two ends of the ring truss vertical web members are hinged to the ring truss lower chord ring cables and the inner ring beams, diagonal web members are arranged between the adjacent ring truss vertical web members, the outer ring beams surround ring trusses, one ends of the asymmetric spoke type radial arc-shaped upper chord members are connected with the inner ring beams, the other ends of the asymmetric spoke type radial arc-shaped upper chord members are connected with the outer ring beams, the lowest points of the asymmetric spoke type lower chord radial cables are connected to the lower chord ring cables of the ring trusses, and the highest points are connected to the outer ring beams. According to the cable-supported space structure, upper chord bending members are changed into axial force members by utilizing the arc design of the upper chord arc-shaped rods, so that the complexity of an asymmetric structure is simplified, the stress is more reasonable, the steel consumption is obviously reduced, and the purposes of attractive building, simple structure, reasonable stress and material saving are achieved.
Description
technical field [0001] The invention relates to the field of large-span space roof structures, in particular to an asymmetric large-span car-spoke type cable-supported space structure. Background technique [0002] The string-supported structure and the spoke-type cable-supported structure have the advantages of less steel consumption, light and beautiful shape, convenient industrial manufacturing and assembly, green and low-carbon, and sustainable development. The traditional car-spoke cable-supported grid structure is biaxially symmetrical, but in actual engineering, due to the requirements of architectural shape and functional use, the roof may have an asymmetric structure. The grid structure brings the following problems to be solved: 1) How to make the structure form asymmetric, while the structural force is relatively reasonable; 2) How to give full play to the mechanical space of the ring truss lower chord and ring cable when the cable bearing part is asymmetric 3) T...
