Abstract:The design standard， load value， substructure system， steel roof structure system， support design and Y￣shapedcolumn design of the natatorium of Pingxiang Olympic Sports Center were introduced. The interior space of the building wereanalyzed， and through multiple rounds of structural scheme comparison and selection， finally steel roof main body adopted astructural system that combines a string beam and a single￣layer grid， which preserves the net height of the building to thegreatest extent. And at the same time， the interior space that the frame column has no impact on the building extend to theroof， and the span of the roof was effectively reduced. Thus a Y￣shaped column， string beam and single￣layer gridcomposite structure was formed. A single steel structure roof model and an overall model with substructure were established，and the internal force and vertical displacement of the two under constant live load were compared and analyzed. The resultsshow that it is very important to accurately simulate the restraint conditions of the support. The steel structure roof has alarge span. Linear buckling analysis was performed on each load combination， and the load combination with the smallestbuckling factor was used as the initial load to perform nonlinear stability analysis. The analysis results all meet therequirements of the code.

Keywords:natatorium of Pingxiang Olympic Sports Center； steel roof structure； Y￣shaped column； linear bucklinganalysis； nonlinear stability analysis
