The project has a structural height of 50.675 meters and is constructed with steel frame-braced + spanning trusses + roof trusses and single-story mesh shell structure.The maximum plan dimension of the building is 158.4×150 meters, transverse spanning 19 axes (1-19 axes) and longitudinal spanning 20 axes (A-V axes).The steel structure mainly consists of core cylinder steel structure, steel frame below the second floor, ring spanning main truss + rotating suspended structural surface between the second and third floors, steel trusses on the third and fourth floors, and mesh shell structure of the atrium immersed theater.The overall structure of the project is complex, with trusses, seismic structural systems, tension cables, pipe trusses and other structures interspersed with each other, and a large number of complex nodes exist.The project won the China Steel Structure Gold Award.
