Improvement of Cook Method Considering Directional Extreme Wind Speed

Abstract:

Based on the analysis of the limitations of the Cook method, an improved method was proposed. The method changed the multivariate probabilistic model of directional extreme wind speeds into an univariate model. Taking the extreme wind speeds in Nanjing area as example, the results of the method and Cook method are compared. Since the method has no limitations in the probability distribution and the assumptions of the Cook method, it has more accuracy in the probability way.
