Through comparing and analyzing the schemes, choose a more economical and easy construction of the welding ball stereoscopic latticed framed form for the main structure of canopy structure, and for the complexity of the bearing structure ofjoints and support column well-justified layout and design, such as the use of support group fix solve the irregular of latticed framed structure and the overturning force and the distorted force problem, the use of inclined composite concrete-filled steel tube columns, composite concrete-filled steel tube long columns to resolve the irregular shape columns of the problem of force and deformation. After the normal service period, it shows. that the latticed framed structure for canopy and the supporting structure below of this project not only meet the requirements of design rules, but also has better design reasonability and economiceffect.
Keywords: stereoscopic irregular steellatticed framed; support group fix; composite concrete-filled steel tube columns; ultra-long Columns; value ofthe wind tunnel experiment
