Complicated High-Rise Structure Design of NingBo-Liansheng Commercial Plaza

Abstract

NingBo-Liansheng International Commercial Plaza is a twin towers with high-connection. It is a complex tall building. The frame-shear wall structure system is used. The connection body is in 21 and 22 layers. The connection system is strong connection and the two storey steel trusses are used. The north and South towers are placed by certain angle, and it designed for the adjustment of plane with layout of shear wall near two tower dynamic characteristics. For the complexity of connection system, the performance of different design goals are worked out for connecting different parts of body as well as the tower. According to the calculation results and to take measures to strengthen the connection body, the connection system can achieve the design target. It ensures the safety and reliability of the whole structure.
