摘要: 深圳大百匯主塔樓高度為 375m,超高層主塔樓是集辦公、酒店、公寓和商業(yè)為一體的綜合體,結構體系采用帶伸臂桁架與腰桁架的鋼管混凝土柱-鋼梁框架-核心筒混合結構體系. 塔樓建筑立面呈紡錘形,外框柱沿曲線布置而形成一系列的斜柱. 介紹了主塔樓結構方案的確定方法及結構設計重點,描述了曲線布置的斜柱體系對抗側(cè)剛度的提高效應、伸臂桁架的選取及優(yōu)化、斜柱引起鋼梁水平軸力的計算方法,基于性能抗震思想對結構及構件進行大震性能評估. 結果表明塔樓整體剛度與構件滿足抗風與抗震的性能要求.

Abstract: The height of the main tower of Dabaihui is 375m. This super high-rise tower is a complex building that includesoffices, hotels, apartments and commerce functions. Structural system is a frame core-wall system with outriggers and belttrusses, and the structural frame is formed with concrete filled steel tubular columns and steel beams. The elevation of thetower is curve-shaped, the frame columns are arranged to a series of inclined columns follow the curve surface. Theselection of the structural scheme of the main tower and the key points of structural design method was introduced. Thestiffening effect of the frame system due to its inclined columns, selection and optimization of outriggers and the calculationmethod for the axial forces of steel beams which is induced by the inclined columns was introduced. By using performancebased seismic method, the performance of the structure and members under rare earthquake were evaluated. The resultsshow that the overall structure and components of the tower meet the performance requirements of wind resistance andearthquake resistance.
Keywords: super high-rise building; outrigger; strengthened story; hybrid structure; concrete filled tube; inclinedcolumn; seismic performance design
