Aerodynamic Damping in the Along-Wind Response of a Tall Building

Abstract
We present an estimate of the aerodynamic damping that affects the along-wind response of an isolated tall building in suburban terrain. The evaluation uses measurements of the external pressures on the windward and leeward faces under wind normal to a building face, and a simplified model of the relation between those pressures and the relative longitudinal fluctuating velocities with respect to the building. The results based on this model suggest that the aerodynamic damping for the case being considered is positive that is, it has a favorable effect and small compared to the mechanical damping. This finding is shown to be independent of the mode shape.Citation
