Wind loads on flat-plate photovoltaic-array fields (nonsteady winds). Phase IV. Final report
Results are presented of a combined experimental (wind tunnel test results) and theoretical analysis utilizing random harmonic analysis techniques to predict the dynamic response and the structural dynamic loads of flat plate photovoltaic arrays due to wind turbulence. Guidelines for use in predicting the turbulent portion of the wind loading on future similar arrays using the results of this study are presented. The dynamic response and the loads dynamic magnification factor of the two array configuration (a four post array and a two post array) are similar. In general, the largest response and dynamic magnification factor occur at a mid chord location on an array and near the trailing edge. A technique employing these magnification factors and the wind tunnel test rms fluctuating pressure coefficients to calculate design pressure loads due to wind turbulence is presented.
