Abstract:The No.9 building in Jinwan Square is 299.65m high with 70 floors on over ground and 4 floors in underground, which is an out-of-code high-rise building structure. Plane dimension of main tower is 50.1m×50.1m. The building area is 150 000 square meters. Because of architectural function, this out-of-code high-rise building elevation includes multiple site back off. Reasonable structure scheme is very important for this building structure, which should satisfy architectural requirement and decrease project cost. It has been described with emphasis on structure scheme formation process about this out-of-code high-rise building. Final structure scheme satisfies architectural requirement and has reasonable mechanical and economy, and passed review of super high-rise building structure.
Keywords: Jinwan Square; out-of-code high-rise structure; reinforced concrete core wall and concrete-filled steel rectangular tube frame; transfer truss; suspension truss; huge column
