Abstract:Shenzhen Bay Innovation and Technology Centre super-tall connected structure is composed of two super high-rise tower buildings 2A and 2B that are connected by two connective bodies. It′s an unsymmetrical twin-tower connected structure.  Two tower buildings are connected as a whole by two 3-layer high connective bodies at 6～9 layer of lower zone and 34～37 layer of higher zone, and the connective body adopts steel truss structure. The project general situation, structural system, structure out-of-code discrimination and seismic performance objectives were first introduced, and then the checking results for performance objective, analysis of the connective truss, stability analysis on skip-layer column, seismic performance evaluation under rare earthquake and seismic strengthening measures. The analysis results show that all the structural indices meet the requirements of specifications and performance objectives.

Keywords:Shenzhen Bay Innovation and Technology Centre； super high-rise building; frame-corewall structure; connected truss; performance objective
