Description

Technical Field

[0001] The invention relates to the technical field of large-span building engineering, in particular to a self-balancing star-shaped arch support structure system. Background Art

[0002] The long-span roof of a football field is a large, circular structure with a high interior and low exterior, with portions convex and concave. The roof's supporting structure is located on the outer perimeter of the roof. If the roof were constructed using a conventional one-way truss structure, the truss structure at the base of the cantilever would be thick, hindering the building's usability. If the roof were constructed using a lattice shell structure, the large internal opening and partially concave roof shape would make it difficult to control the roof's vertical deformation, and would also generate significant horizontal thrust on the lower supporting structure, increasing its burden. Designing a roof structure suitable for this type of roof presents a technical challenge that those skilled in the art urgently need to address.
