Abstract:The design and structural analysis on asymmetrical rigid-connected arch type twin-tower skyscraper with irregular distribution of stiffness and masses in two towers are studied. Based on the researches on two projects, the requirements on the selection of analysis software are put forword, and the influence of the rigid-connection on the dynamic behavior of the whole structures is discussed, and the computational methods on the overturning moment of the two towers are suggested. The design of the connection body is introduced.
