摘要
丽泽SOHO中心地上部分由两个反对称的混凝土筒体-单侧弧形钢框架结构组成,两个单塔之间由4道椭圆形腰桁架及连桥连接组成一个整体,结构高度190.32m,为体型复杂的混合结构体系。配合平立面的曲线体型,着重讨论核心筒内型钢节点的构造设计以及与混凝土钢筋的协调处理,外框架Y形柱节点、连桥复杂连接节点等具代表性钢结构节点的设计原则及加强措施,使其在满足相应性能目标的同时易于施工。
The over ground part of LEEZA SOHO Centre consists of two anti-symmetry corewall-single side arc steel frame structures. The two single towers are connected by four elliptic waist trusses and the connecting bridge to form a whole integration. The structure with complex figuration adopts mix structure system with structure height of 190. 32m. Considering the curve shape of the plane and facade, representative steel structure joint design principles and strengthening measures were focused on including the structural detail design of the corewall internal section steel joints and its coordination treatment with reinforced concrete, the outer frame Y-shaped column joint design and complicated connecting joint of the connecting bridge, in order to meet performance objectives and easy construction.
