Wind-induced Response of High-rise Tower Structure with Fluctuating Wind Load

Wu Weiguo

Abstract

According to the characteristics of fluctuating wind,the fluctuating wind load was simulated,its validity was confirmed and samples of the fluctuating wind load were obtained.Established 3-D finite element model of the tower,and calculated the wind-induced vibration response of the tower by time-history analysis method.The results indicate that the wind-induced response is larger at the top of high-rise tower structure under the function of fluctuating wind load,and the effective method was suggested to control its wind-induced vibration response.
