This paper describes a method for determining the universal wind load distribution that reproduces the maximum load effect on structural members. The method is applied to a cantilevered roof model to estimate the equivalent static wind load. The resonant component of the load effect cannot be ignored in the cantilevered roof. The equivalent static wind load for background components is estimated by using of the eigenvectors of wind force calculated by POD analysis. The equivalent static wind load for the resonant component is estimated by using equivalent static loads that reproduce the same shapes to the eigenvectors of the model. In addition to the mean, the background and the resonant component, the total equivalent static wind load can be estimated. The maximum load effects induced by the equivalent static wind load show good agreement with the true maximum load effects calculated by response analysis.
