Abstract:The steel shed of wrestling stadium aid for Senegal is a 210m large-span spatial steel arch structure that composed of the main arch, rear arch and the sub truss. Structural system selection, structural static analysis, stability and arch foot joint analysis were introduced. The analysis result shows that it′s rational to adopt diamond section in the arch structure, to adopt inverted triangular spatial truss in rear truss and sub truss and to adopt vertical sub truss, linking truss and support arrangement. The cross section of the rod has uniform mechanism, and joint structure is simple and spatial integrity of structure is strong. It′s rational to adopt the universal ball hinged support in the design of the main arch foot joint, and it can meet the design requirements.

Keywords:wrestling stadium aid for Senegal; large-span spatial steel structure; arch truss; static analysis; stability analysis; joint analysis
