This paper discusses the equivalent static wind load that reproduces the largest load effects in structural member (hereafter referred to as the universal ESWL). In this study, the universal ESWL is shown by a combination of eigenmodes calculated by POD analysis of fluctuating wind pressure. Applying singular value decomposition to a matrix of eigenmodes by the influence function optimizes the universal ESWL combination. This method is applied to large cantilevered roof models. The largest load effects for bending moment (hereafter referred to as BM) and shear force (hereafter referred to as SF) are determined to estimate the universal ESWL. The largest load effects reproduced by the universal ESWL show good agreement with those directly estimated by time-domain response analyses.
