Abstract:China Minsheng Bank Mansion is reconstructed and expanded by the methods of RC column postcovered steel tube, composite steel and concrete floor substitution and core wall externally bonded steel frames strengthen etc. The height of building is increased from 1347m to 1886m and the total area is enlarged 30 000m2. Contents of structural design for the mansion are introduced, including structural system establishment, structural analysis, seismic design, structure reinforcing methods, high strength material selection, substitute subsequence from concrete floors to composite steelconcrete floors and joint connection etc.
Keywords:super highrise building; reconstruction; expansion; substitution; postconcretefilled steel tubular reinforced column; edge element; steel bonding reinforcement
