Abstract：In order to ensure the safe and stable operation of engineering structures under long-period wind speed，the influence of the extreme value of non-stationary non-Gaussian wind speed on engineering structures should not be ignored.In this paper，the field measured wind speed is taken as the research object. According to whether the time-varying mean or the time-varying root mean square is excluded from the wind speed sample，we set four wind speed working conditions.And the extreme value of non-stationary non-Gaussan wind speed of the four wind speed working conditions is obtained by combining the stationary transformation method and Sadek-Simiu method.The research results indicate that the wind speed extreme value obtained by excluding the time-varying mean value kept basically unchanged with the original wind speed，while the wind speed extreme value obtained by removing the time-varying root mean square generally increased by more than 30% 。（剩余9198字）
