THE RESEARCH ON SIMULATION OF WIND SPEED TIME-HISTORY OF LONG SPAN SUSPENDED DOME STRUCTURE

With the developing of long span structure,more and more attention is paid the influence of wind load on structures.At present,the domestic research on this is just started,especially for the suspended structure,the research on it is much less.The wind load based on numerical simulation methods are widely used in the structural analysis of wind-induced vibration.AR model is applied in wind speed time-history,its rapid and accurate simulation is conducted for the long span structure using mix-programming of VC and Matlab and the integral program of Romberg.Its correctness is proved by Olympic Badminton Gym.The simulation of wind speed time-history has laid a foundation for the analysis of wind-induced vibration of the suspended dome.
