The application of a partial boundary layer wind tunnel to the examination of dynamic response of cantilever structures to wind excitation

Abstract

The characteristics of a partial boundary layer wind tunnel are established for simulated air flow over an urban environment and the wind excitation of small cantilever structures is examined. The process of modelling the natural wind is explained and techniques are outlined for the measurement of mean and r.m.s. response of small scale structures. The significance of such information for indicating the dynamic response of large scale structures is discussed.
