Abstract: The tower building height of Wujiang Greenland Center super high-rise project is 358m. The core tube is dividedinto two independent parts starting from the 33rd-floor hotel atrium. The structural system is innovative and unique, whichbrings new challenges to the structural design. The main structural characteristics of the super high-rise tower wereexpounded in detail, the main process of its structural design and the related seismic design methods were introduced, andthe conceptual design in the seismic design process was focused on, and the key problems such as the reinforcement layerdesign, cross bracing design and tower crown structure design were solved. The analysis results show that the super highrise tower structure can meet the predetermined seismic performance targets, all the structural analysis indicators can meetthe requirements of the current code, and the special components such as reinforcement layers and cross bracing arereasonably stressed and have a certain safety reserve.

Keywords:super high-rise tower building; core tube; cross bracing; tower crown; reinforcement layer; composite structure
