【Abstract】 Based on the steel tower of a tall reinforced concrete building in Xi′an,two analytical models are chosen.One is the two dimensional lumped mass dynamic model and the other is the three dimensional finite element static model.The dynamic character of high rise tower and the dynamic control of damper to the wind response of the high rise tower are discussed.The research result shows that the fluid viscous damper for structural control can reduce the vibration response of steel tower under wind excitation effectively.更多还原
