The wind action on structures may be represented by peak velocity pressures, in conditions of strong wind, or by the basic stochastic descriptors of the velocity fluctuation, i.e. turbulence intensity, power spectral density and correlation between velocities at different points of the structures and probability distribution. The energy of turbulent fluctuations is distributed over a range of frequencies and the turbulence intensity is changing with height and terrain category. The resonance response due to gust wind takes into account also motion of the structures itself. Application examples will be given for the multi storey concrete and steel buildings.
