ResumoThis paper describes a complete package of techniques for the acquisition, analysis and processing of wind speed and wind pressure data in order to arrive at the best possible values for use in the design of static structures against wind loads. For the purposes of this paper, static structures are defined as those in which the dynamic response is insignificant and can be ignored in the design calculations. The techniques described comprise: The definition of speed and loading coefficient parameters so that, for practical purposes, they are statistically independent. The treatment of analog full-scale data records by trend removal, so as to render such data stationary and compatible with model-scale data, and thus amenable to the application of standard statistical techniques. Extreme value analysis of wind speed and wind pressure data. The use of the extreme value parameters so obtained to make a fully probabilistic assessment of wind loads on structures. All these ingredients are essential to the accurate assessment of wind loads. The fact that such statistical methods have not previously been fully implemented in the analysis of both full-scale and model-scale data is one reason for the lack of consistency between full-scale and model scale on the one hand, and between different model-scale tests on the other. The adoption of these methods should help to resolve some of the difficulties, enable simulation methods at model scale to be better assessed, compared and developed, and also provide more accurate data for design. The treatment of dynamic structures is not covered by this paper.
