Abstract: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.
Keywords:super high-rise building; mix structure; complicated connection; nonlinear analysis; cast steel joint
