In many studies and current design wind codes, not all turbulent componants are considered to estimate the displacement responses of structures subjected to wind loading. This limitation may result in estimations unsafe to structures. This paper presents an analytical approach for buffetting analysis of slender vertical structures in cross-wind direction. Effect of different turbulent components on structural displacements is investigated. A numerical application on a real structure will illustrate the theory and point out the limitations of conventional approaches used in engineering practice.
