Large Eddy Simulation of Wind Loads on a Low-Rise Structure and Comparison with Wind Tunnel Results

Abstract:

This work presents estimates of time histories of pressure coefficients at several taps on the roof of a 1/200 model of a 200 x 100 x 20 ft low-rise building with a 1/24 slope gable roof building. The estimates were obtained by large eddy simulation (LES). The first and second moments as well as peaks for the time histories are compared with those obtained in boundary layer wind-tunnel measurements at the University of Western Ontario. It is noted that the computation times required to obtain records of length comparable to wind tunnel records are at present prohibitively large.
