Abstract

The paper presents a generalization of existing analytical approaches to determine the across-wind aerodynamic damping of tall structures through the quasi-steady theory. The theory takes into account the nature of non-uniform wind, structural mode shapes and the variation of structural parameters. Numerical applications on a prototype high-rise building and a real sculptural tower point out that the common approach may be over simplified, giving rise to inappropriate predictions of the aerodynamic damping. The role of the structural mode shapes, usually being neglected for uniform structures, is then highlighted.
