Abstract:The steel structure designs of professional football stadium and the gymnasium in the Zhaoqing New District Sports Center were introduced. Among this, the professional football stadium is the cantilever steel box girder structure, and the gymnasium is the double connected suspendome structure. The structural characteristics of Zhaoqing New District Sports Center were illustrated based on  the structural system selection, eigenvalue analysis, response spectrum analysis, stability analysis and elastic analysis. In view of the structural weaknesses that appeared in the process of calculation, measures of taking control of the steel structure stress ratio and strengthening the node construction measures were taken to improve its safety reserve. Roof steel structure design can meet the specification requirements, and can effectively achieve architectural forms.

Keywords:Zhaoqing New District Sports Center; cantilever steel box girder; suspendome; stability analysis
