Gives methods for determining the gust peak wind loads on buildings components that need to be considered in design using equivalent static procedures. Gives two alternative methods: a directional method in which effective wind speeds and pressure coefficients are determined to derive the wind loads for each wind direction; a standard method that uses a simplified procedure to obtain a standard effective wind speed which is used with standard pressure to determine the wind loads for orthogonal design cases. Does not apply to buildings that are particularly susceptible to dynamic excitation.
