Comparison of Field and Wind Tunnel Pressure Coefficients for a Light-Frame Industrial Building

Publication: Journal of Structural Engineering
Volume 135, Issue 10

Abstract

This technical note describes how full-scale observations of external pressure coefficients for a single storey industrial building located in Quebec City, Canada compared with matched scale at 1:200 wind tunnel measurements. Wind pressure was measured by a grid of 20 pressure taps at wall and roof surfaces. Both mean and peak pressure coefficients on the envelope of the actual building compare well with values obtained in the wind tunnel.
