【Abstract】 Based on the design of the steel tower on a reinforced concrete tall building in xi’an, two analytical models were chosen in this paper. One is the two-dimensional lumped mass dynamic model and the other is the three-dimensional finite element static model. Then, the dynamic characteristics of the steel tower and the control of the dynamic response for the steel with the fluid viscous damper tower are discussed. The research results show that the fluid viscous damper for structural control can reduce the vibration response of steel tower under earthquake excitation effectively.更多还原
