Abstract:In the structural design of Quanzhou Stadium, the pressure of axial force of the ground arch of steel cantilevered end-capped beam is transferred through the reinforced concrete special-shaped column down to the base and pile foundation, and tension force is transferred through the section steel embedded under the pin shaft plate at the bottom of ground arch to the steel reinforced concrete special-shaped frame of the main structure. The design points of the overall inclined torch column and lamp column were introduced. Two methods of thickening steel plate transition and using diaphragm plate for transition connection were proposed to solve the problem of cross-section torsional issues encountered by non-circular cross sections including rectangle and H-shaped sections to form a spatial curved surface or spatial folding surface. Two treatments of the beam-floor structure and the foundation treatment were proposed for indoor ground settlement after completion of foundation of main structure of the stadium. The structural form of concrete special-shaped frame takes into account the convenience of setting up the curved curtain wall of the fa-ade of the stadium, so that the overall building structure can obtain the maximum rationality and economy.

Keywords:Quanzhou Stadium; axial force of ground arch; sectional spatial torsion; ground settlement after completion; special shaped frame
