The Structural Design of a Cantilevered Roof System of a Stadium Stand

Abstract:

In this paper a simple statically determinate and indeterminate truss structure is chosen as the model for the design of the stadium stand. The design simplifies the canopy structure, considering actual handling of the connection of nodes; fewer nodes would be chosen for the convenience of installation. The supporting frame is put slantwise between the roof and vertical walls to improve the safety and reliability of the cantilevered structure. The roof truss adopts bidirectional and orthogonal divisions, adding up inclined trusses in divisions of upper and lower surfaces, thus increasing space stiffness. Schematic drawings, internal forces and material processing lists are put forward in this paper, aiming at less material, simple construction, saving manual labor and financial resources and satisfying the masses on the basis of enough intensity and stiffness.
