Through continuous development of the spatial structure of a century, in terms of grid structure, in addition to the grid, mesh shell, membrane structures, tensegrity system, opening and closing of new members roof, collapsible structure are spatial structure. Research and application of high-performance steel. Using a variety of technical measures spherical grid, improve the carrying capacity of stainless steel grid, the steel play higher performance is a major direction for future development of the steel structure. Further improve the design criteria. Existing norms adopted are approximate probability limit state design approach that there are still shortcomings, to further improve the response to continue to study design criteria. Spherical grid, grid, Guangxi Guangxi Galaxy Galaxy is provided by the metal structure Engineering Limited. Guangxi Galaxy Metal Structure Engineering Co., Ltd.
