Cable structure design for roof canopy of Dalian Suoyuwan Professional Football Stadium
Aiming at the cable-membrane canopy of Dalian Suoyuwan Professional Football Stadium with wavy shape,a double-layer cable-net structure with spoke-type upper oblique and lower radial was proposed and designed.The outer side of the cable truss is supported by a steel pressure ring,and the inner side is provided with a cable pulling ring.According to the wind tunnel test and the numerical simulation report of wind-induced snow drift,the wind and snow resistance,temperature resistance and seismic resistance of the canopy structure were calculated and analyzed.The initial form-finding analysis,dynamic characteristic analysis,structural deformation and stress analysis,structural overall stability analysis,anti-progressive collapse analysis and finite element analysis of key nodes of the canopy structure were carried out.The analysis results meet the requirements of structural design control indicators,and the structural design conforms to the architectural design concept,and make structure and architecture coordinated and unified,and the structure is safe,economical and reasonable.
