Abstract: The NEO Building comprises a 260m tall 61-storey tower, a 12m tall steel structure in the roof and a three storey basement. Reinforced concrete frame-core wall structure is adopted to the main tower. The bottom part of the perimeter frame adopts steel reinforced concrete column. Concrete core column is applied in the bottom of core wall. Floor structural system consists of one-way reinforced concrete beam. The proper arrangement of the core wall and the reasonable section of column and beam is proposed to avoid setting refuge story with outriggers and belt members. The beam which cross section varies in horizontal direction is used to connect the perimeter frame and the core wall in partial story. By means of above measures, the lateral stiffness varies evenly along tower height and the economical objective of the structure have been well realized.
Keywords: skyscraper; RC frame-core wall structure
