Abstract
The paper presents a new proposal for universal wind load distribution simultaneously reproducing maximum load effects on a large-span cantilevered roof. It discusses the equivalent static wind load (ESWL) that reproduces the maximum load effects in structural members. This load is referred to hereafter as the universal ESWL. In this study, the universal ESWL is shown by a combination of eigenmodes calculated by Proper Orthogonal Decomposition (POD) analysis of fluctuating wind pressure. By applying singular value decomposition to a matrix of eigenmodes multiplied by the influence function, the optimal universal ESWL is found. This method is applied to large cantilevered roof models. The maximum load effects for bending moment and shear force are determined to estimate the universal ESWL. The maximum load effects reproduced by the universal ESWL show good agreement with those directly estimated by time history analysis.
