To predict typhoon design wind speed of buildings in typhoon prone region more efficiently and accurately, probability distributions of typhoon key parameters are first fitted by using the historical typhoon wind data during 1949 and 2012 in southeast china costal region. Then, the empirical typhoon wind field model with new formula for Holland radial pressure profile parameter B is presented. Finally, in conjunction with Monte Carlo simulation method, by using typhoon extreme wind speed analysis method, typhoon extreme wind speeds with different return periods for Hong Kong are obtained. The simulation results are compared with these results obtained by using observed data and Hong Kong wind code. The effectiveness of predicting typhoon extreme wind speed by using this empirical typhoon wind field model is validated.
