Time History Analysis of Pulsating Wind Vibration for Multifunctional Vibration-absorption Megaframe Structure

Through an engineering example,the analysis modes of multifunctional vibration absorption and ant vibration megaframe structure have been established,and time history of velocity for pulsating wind has been randomly simulated.From this,the time history response of pulsating wind vibration displacement and acceleration on multifunctional vibration absorption megaframe structure have been studied.The results seem to indicate that the pulsating wind vibration response can be evidently reduced on multifunctional vibration absorption megaframe structure,which may be a new type of promising system.
