Probability statistic expressions of pulse wind velocity and pressure are investigated.By the auto regressive model (AR model) in time series analysis,the time history of pulse wind load acting on high rise building structures and varying along with the space positions has been concisely imitated.A real project is treated as an example.The results indicate that analysis and treatment methods presented here are reasonable and feasible.
