Architecture Engineering and Science

This project is based on the original stand of China University of Geosciences Stadium. First, the original concrete canopy is removed, and then a steel structure canopy is added to the stand. The overall structure adopts a steel pipe truss structure, and the roof maintenance material adopts a single-layer reticulated shell supporting membrane structure. This structure is a large cantilevered structure with independent columns. In order to reduce the vertical displacement of the canopy structure, the vertical and horizontal truss structure is adopted, and the double-column joint foundation form is adopted to improve the overall stability of the structure. According to the bearing capacity requirements of the whole structure under the action of wind load and other live loads, the force analysis of the structural members is carried out, including the analysis of the overall vertical deformation of the structure, the stress analysis, and the force analysis under the action of earthquakes. This structure is a large cantilevered independent column structure, and the stability control of the overall structure must meet the requirements of the specification. The buckling modes of the structure are analyzed. The buckling analysis results show that the structure does not suffer from overall instability under normal service loads.
