Abstract
Currently, there are no national or international guidelines for the wind uplift resistance of architectural metal roofing systems. Given the increasing use of metal as roof covering materials/systems, it has been determined that there is a need for the development of a metal roof wind resistance guideline or standard, that would be applicable to all regions of Canada. In this paper, standing seam metal roof-covering systems were investigated under dynamic wind load conditions. Air leakage of the structural deck is an important factor for wind uplift performance of the architectural metal roofing systems. It has been noted that the wind uplift resistance is increasing dramatically as the air leakage ratio i.e., the amount of leakage area compared to the total roofing deck area, is decreasing. A modeling method was also described to quantify the metal roofing system response by simulating the wind gusts over roof specimens of different leakage levels that can represent typical field assemblies. Based on the laboratory experiments, a simplified design guideline was developed for the wind uplift resistant design of roof assemblies with metal covering located in the province of British Columbia, Canada.
