A revised Hermite peak factor model for non-Gaussian wind pressures on high-rise buildings and comparison of methods

摘要

To better estimate the non-Gaussian extreme wind pressures for high-rise buildings, a data-driven revised Hermite-type peak factor estimation model is proposed in this papar. Subsequently, a comparative study on three types of methods, such as Hermite-type models, short-time estimate Gumbel method (STE), and new translated-peak-process method (TPP) is carried out. The investigations show that the proposed Hermite-type peak factor has better accuracy and applicability than the other Hermite-type models, and its absolute accuracy is slightly inferior to the STE and new TPP methods for non-Gaussian wind pressures by comparing with the observed values. Moreover, these methods generally overestimate the Gaussian wind pressures especially the STE.
