摘要: 杭州智慧大廈的兩棟高層建筑分別由四個不同尺寸盒式建筑體塊沿高度方向交錯疊合形成,有較多內退、外挑及通高空間,并通過連接體連接,造型復雜。結合建筑造型,采用鋼管混凝土框架-核心筒結構體系,外挑空間采用懸挑桁架抬柱或吊柱形式。首先對該結構進行超限情況判定,采取相適應的抗震性能目標及超限應對措施。然后通過性能化分析,總結結構的整體受力特性,并通過彈塑性時程分析檢驗關鍵構件在大震下的性能。最后,針對關鍵部位及設計難點,補充連體結構設計、節(jié)點分析、樓蓋舒適度分析、穿層柱屈曲分析等。分析結果表明,結構具有較好的抗震性能,結構安全可靠。

Abstract: The two high-rise buildings in the Hangzhou Wisdom Building are respectively formed by four box-shapedbuilding blocks of different sizes that are staggered and superimposed along the height direction. There are many interiorfacade setbacks,exterior overhanging and full-height spaces,which are connected by connecting bodies with complexshapes. Combined with the architectural shape,the CFST frame-core wall structural system was adopted,and the exterioroverhanging space adopted the form of cantilevered truss lifting column or hanging column. Firstly,the out-of-code situationof the structure was determined,and the appropriate seismic performance targets and out-of-code countermeasures weretaken. Then,through performance-based analysis,the overall mechanical characteristics of the structure were summarized,and the performance of key components under rare earthquakes was tested through elasto-plastic time-history analysis.Finally,according to the key parts and design difficulties,the design of connected structure,joint analysis,floor comfortanalysis,and buckling analysis of skip-floor columns were supplemented. The analysis results show that the structure hasgood seismic performance,and the structure is safe and reliable.
Keywords:transfer truss; cantilever structure; CFST frame-core wall structure; lifting column; hanging column; connectedstructure; floor comfort; skip-floor column
