As the vortices around the structure are transferred to the dynamic wind load, across-wind vibration is induced, and the magnitude of the vibration is larger than the along-wind vibration when the height of the structure is increased. In this study, in order to quantitatively evaluate across-wind response, the vortex-induced load components are classified according to their own original source, and the effect of each component on the vibration is analyzed. The load is identified from the response of the structure by inverse problem, and these load components are obtained by Kalman filtering based on the state equation realized from the distribution characteristics of loads spectrum in the frequency domain. The proposed load decomposition process for vortex-induced load components is verified by performing an aero-elastic model test for the circular cylinder model in the atmospheric boundary layer wind tunnel, and the pattern in which each load component contributes to the across-wind response is analyzed, and finally the original source of the loads as well as the unique behavior of across-wind response can be precisely understood.
