Description
Technical Field
The invention relates to the field of large-span space roof structures, in particular to an asymmetric large-span spoke type cable bearing space structure.
Background
The string supporting structure and the spoke type cable bearing structure have the advantages of small steel consumption, light and attractive appearance, convenience in industrial manufacturing and assembly, greenness, low carbon, sustainable development and the like. Traditional spoke formula cable holds lattice construction and is the biax symmetry form, but in actual engineering, because requirements such as architectural modeling, function use, the room lid probably is asymmetric structure, because the structure is asymmetric, has just brought the following problem for spoke formula cable holds lattice construction and needs solve: 1) when the structural form is asymmetric, the stress of the structure is relatively reasonable; 2) the mechanical space action of the lower chord ring cable of the ring truss is fully exerted when the cable bearing part is asymmetric; 3) the outer ring beam may be stressed under certain operating conditions, how the structural design takes into account its adverse effects, and so on. Therefore, when the asymmetric roof structure adopts the spoke type cable bearing grid structure, great design difficulty exists, and thus a novel asymmetric large-span spoke type cable bearing space structure needs to be provided to solve the problems.
At present, various chord support structures and spoke type cable bearing grid structures are widely applied to large-span roof buildings such as large and medium-sized stadiums and exhibition buildings. Because the upper chord members of the various structures are generally bent members, and when the span is large, the brace rods are required to be arranged to ensure that the section of the upper chord steel member is reasonable, as disclosed in patent application No. 201410216557.9, the large-opening spoke type cable-supported grid structure comprises an upper chord rigid grid system and a lower chord tension cable rod system, wherein the upper chord rigid grid system is a structure with a large opening in the middle, the lower chord tension cable rod system comprises a ring cable arranged below the opening of the upper chord rigid grid system correspondingly and a plurality of radial cables arranged in a spoke type along the radial direction of the ring cable, the end parts of the radial cables are hinged with the ring cable, brace rods are arranged between the radial cables and the upper chord rigid grid system and along the arrangement direction of the radial cables, the two ends of the brace rods are respectively hinged with the radial cables and the upper chord rigid grid system, and diagonal web rods are arranged between the ring cable and the upper chord rigid grid system and along the circumferential direction of the ring cable, and two ends of the diagonal web member are respectively hinged with the ring cable and the upper chord rigid grid system. Although the patent application changes the cantilever stress state of the upper chord rigid grid system into the stress state of the elastic support continuous beam through the high-strength material characteristics of the radial inhaul cables, and solves the rigidity problem of the integral structure after opening, the defect of the upper chord rigid grid system is that the cantilever stress state can be changed into the stress state of the elastic support continuous beam by arranging the stay bars, but the problem is also caused because theoretically, the stay bars and the lower chord radial cables can play a role only when the upper chord rigid grid system deforms, and the contradiction exists between the design of the upper chord rigid grid system and the linear design of the lower chord radial cables. When the structure is asymmetric, the stress of the stay bar is also asymmetric, which causes the determination of the radial inhaul cable force distribution to be complicated and difficult, and the space function of the ring cable is difficult to be fully exerted.
