Abstract

Wind action on structures is commonly estimated under the stationary assumption that is related to the phenomena that occur in neutral atmospheric conditions at the synoptic scale with velocity profiles in equilibrium with the atmospheric boundary layer. Nevertheless, when thunderstorm outflows are concerned the wind induced load description should take into account its inherent non-stationary features. In this paper a non-stationary model is proposed to describe wind velocity fluctuations of a typical thunderstorm in the northern Italian coast. This model can be obtained by modulating both amplitude and frequency of a stationary process. First, experimental time histories are used to calibrate the non-stationary model, then a parametric dynamic response study to stationary and non-stationary wind loads is finally investigated.
