Prediction of Peak Wind Loads on Low Rise Structures

摘要

A new procedure to derive the distribution of peak pressure and wind load coefficients from individual sample records is presented. The procedure is applied to field data obtained from the experimental building at the Wind Engineering Research Field Laboratory (WERFL) and to wind tunnel measurements on generic flat-roof models of similar geometry made at Clemson University and the University of Western Ontario (UWO). From the wind tunnel data, load coefficients based on variable tributary areas are compared with the provisions of the ASCE 7 Standard.
