Abstract

An application of the new active aerodynamic control device proposed in the companion paper is presented in this paper. The equations for closed-loop dynamics of tall buildings under the influence of AFS are derived based on the theory presented in the companion paper. The approximate formulae based on the dynamic models are also derived to develop a design methodology for AFS application to tall buildings. An example is presented to illustrate some important issues related to design. Influence of various parameters is evaluated numerically and several practical aspects related to the installation of AFS on tall buildings are investigated.
