［摘要］中国尊大厦外框筒为巨型结构，各构件内力巨大，其布置力求规则以传力直接。根据建筑外形及结构传力要求，巨型柱分叉后的形心均在同一竖直面内，同时控制其一角点到幕墙外皮的最小距离，由此确定巨型柱的空间定位。巨型柱均以水平面为控制截面，采用分段折线的形式控制与外完成面的距离，转折标高为转换桁架的上弦上皮或下弦下皮标高。转换桁架弦杆的截面为平行四边形，即一条边水平，另一条边沿巨型柱外皮，转换桁架腹杆、巨型斜撑以及次框架等构件也采用平行四边形的截面形式。从水平视角看，外框筒结构构件不出现重影，构件之间的连接也不出现错边，保证巨型结构传力的同时，又完美体现建筑效果。

Abstract:The exterior framed tube of China ZUN Tower is a mega structure. Each of its elemental structure can sustain large internal forces and elemental layout should be as uniform as possible to achieve direct load transfer. According to the requirements for architectural features and structure load paths, the centroids of areas should locate in the same perpendicular plains after the splitting of mega columns and the minimum distance between corners and skin of the glass curtain walls was controlled simultaneously to determine the dimensional space orientation of the mega columns. Polylines were used for the mega column horizontal control surfaces to keep the required distance to the outer finished surfaces. The turning levels were at the same levels of upper or lower surface of transfer trusses. The cross sections of the truss chords were parallelograms, meaning two surfaces were horizontal and others were along the skin of the mega columns. The cross sections of truss braces, mega braces and secondary frames were also parallelograms. Double visions of structural elements of exterior  framed tube were eliminated from horizontal prospective and the connection between components never appeared the dislocation. With the mega structures efficiency assured, the architectural intentions were achieved.

Keywords:China ZUN Tower; exterior framed tube; mega structure; control surface; integrated design method
