LARGE-SPAN CORRIDOR STRUCTURE COMPOSED OF ARC-SHAPED CANTILEVER TRUSSES AND STAY CABLE SUPPORTING STRUCTURES AND CONSTITUTING METHOD THEREOF

A large-span corridor structure composed of arc-shaped cantilever trusses and stay cable supporting structures is provided, comprising cantilever trusses with arc-shaped facades, orthogonal connecting trusses at a corridor, connecting trusses at cantilever portions, corridor truss structures, and stay cable supporting structures; the cantilever trusses with arc-shaped facades are composed of two sets of ultra-long cantilever trusses with arc-shaped facades and triquetrous planes which are supported by ground and symmetrical, and each are set of ultra-long cantilever trusses with arc-shaped facades and triquetrous planes are formed of several ultra-long cantilever trusses with arc-shaped facades and triquetrous planes arranged in parallel at a certain distance. The beneficial effects of the present disclosure are: the large-span corridor structure composed of arc-shaped cantilever trusses and stay cable supporting structures provided serves the combination of the cantilever trusses with arc-shaped facades and the orthogonal truss at the corridor as the supporting truss core system, and the performance of lateral force resistance and torsion resistant of the overall structure can be enhanced by the connecting trusses at cantilever portions.
