ANALYSIS INTERPRETATION MODELING AND SIMULATION OF UNSTEADY WIND PRESSURE DATA

This paper addresses the analysis, modeling and simulation of measured full-scale wind pressure and velocity data. The records exhibit both non-Gaussian and non-stationary features, and are ideal for the applic ation of a number of contemporary methods for handling the types of pr oblems associated with these characteristics. Modeling the probability density function (pdf) of non-Gaussian pressure is first addressed, f ollowed by the simulation of pressure data through new static transfor mation techniques. The non-stationary portion of the pressure data is isolated and decomposed into a set of localized basis functions using wavelet transform techniques. Wavelet analysis is used for the identif ication of energy flux in time and for simulation of the non-stationar y wind velocity records.
