Dynamic response of a triangular building model in an atmospheric boundary layer

Abstract

Experimental results for longitudinal, lateral and torsional responses of a triangular building model of aspect ratio 1:4.6 in an atmospheric boundary layer are presented, using a linear model with three degrees of freedom. By varying the angle of incidence of the wind, the critical angles for longitudinal, lateral and torsional motions are determined. It is found that the root mean square displacements of the model vary exponentially with the reduced velocity. © 1988.
