I. Project Overview This project is a national sporting committee badminton, gymnastics hall, two sports buildings, the upper is a badminton hall, and the lower is a gymnasium for badminton and gymnastics training. The main span is 22 meters and the building area is 3762.17 square meters. Its structure is a two-layer prestressed frame structure. The first floor roof frame beam adopts post-tensioned self-anchoring prestressed curve reinforcement, and the upper floor accommodates badminton space requirements. The frame cross-beam is adult-shaped double-pitch roof roof. The slabs are all made of prestressed long-direction circular orifice plates. Between the slabs and the slabs, appropriate slab joints are left and poured into No. 200 concrete to enhance the overall stiffness of the structure. Frame column
