Abstract
Background to the generation of perceptible accelerations in tall buildings is described with the conclusion that these tend to be dominated by the cross-wind response to wake (vortex) excitation. A sensitivity analysis demonstrates the dependence on wind speed, damping, building massiveness and the cross-wind force spectrum. The remainder of the paper gives guidelines to the way in which the shape of configuration of a building may be directed to achieve reductions in the cross-wind force spectrum and hence reductions in acceleration response to meet occupancy comfort criteria.
