Design of quasi mega frame out-of-code structure of Alibaba Shanghai headquarters
Alibaba Shanghai headquarters building adopts the quasi mega frame structure system,and the main structural members all adopt steel structures.The general situation of the tower out-of-code structure design was systematically introduced,and the structural characteristics and difficulties of the quasi mega frame of this project was expounded.In view of the irregularity of the whole structure of the tower,the seismic performance target and seismic strengthening measures of the structural design were proposed.The results of structural overall analysis show that the overall index and seismic performance of the structure can meet the established design requirements.The special and key parts of the structure were calculated and analyzed to ensure the reliability of components and joints and their key role in the overall structure.
