Abstract: Zhejiang Wisdom Gate is the super high-rise twin-tower with a total height of 280m, and it is one of thelandmark buildings in Hangzhou. The stress analysis of concrete corewall + giant column frame + steel diagonal bracestructure was carried out under gravity and wind load; the dynamic characteristics of the structure under earthquake and themechanical characteristics of the giant column diagonal braced outer frame were studied; the stress analysis and structuraldesign of the key joints of the giant column diagonal braced outer frame were introduced; in addition, through thesimulation of the whole process of tower construction, the influence of concrete shrinkage and creep of wall column on theinternal force of steel giant column and diagonal brace was analyzed, and it puts forward that sufficient safety margin shouldbe considered in the stress ratio in the component design to ensure the structural safety.
Keywords:Zhejiang Wisdom Gate; concrete corewall; giant column frame; steel diagonal brace; construction simulation;shrinkage and creep; K-shaped joint
