Abstract:Guangzhou East Tower adopts mega frame-corewall with outriggers as its main structural system. To satisfy the architectural and seismic design requirements, the external wall of corewall adopts composite C80 high-strength concrete shear wall with embedded double steel plates. The composite shear wall with embedded double steel plates features high ultimate bearing capacity, significant ductility, good energy dissipation ability and good seismic behavior. It has a great prospect of application in super-tall building structures. The design considerations and key points of construction of composite concrete shear wall with embedded double steel plates were emphatically introduced, including calculation of bearing capacity, construction measures, typical joint connections, steel plate segmentation and hoisting, crack control, etc.. The calculation results show that all the indices can meet the requirement of architectural function and the requirements of  the lateral stiffness and bearing capacity of the structure.

Keywords:composite concrete shear wall embedded with double steel plates; C80 concrete; seismic behavior; crack control
