Abstract:  Hangzhou Citizen Center which is located at the side of Qiantang River is a six-tower connecting complex tall building. The wind load and wind-included responses are analysed by rigid model wind tunnel test and aeroelastic model wind tunnel test; the selection of basement, the deformation joint setting of enlarged base structure and the design of foundation are introduced; the behaviors and construction measures of multi-tower connecting structure and skybridge support are also researched.
