An improved full-order method is presented for estimating the probabilistic annual maximum wind load effects of rigid structures. The improved method is capable of integrating any type of asymptotic extreme value distributions concerning annual maximum wind speed and peak load coefficient. The estimations with the modeling of annual maximum wind dynamic pressure and annual maximum wind speed are compared which reveals the upper tail sensitivity issue in the probability analysis. The relationship of the first- and full-order methods is established and the efficacy of the first-order method is examined. A comprehensive analysis is conducted to investigate the influence of the randomness of mean wind speed and peak load coefficient on the wind load effects with given mean return intervals and the wind load factor. Finally, the influence of different type of distributions of annual maximum wind speed and peak load coefficient on the probabilistic wind load effect is quantified.
