Study of wind loads on asphalt shingles using full-scale experimentation

Asphalt shingles constitute more than 80% of the roofing materials in current residential housing United States. Many post-disaster surveys have reported failure these elements below design level wind event. Research to realistically model aerodynamics asphalt at full-scale is limited, resulting knowledge gaps peak loads and effects permeability. In this study, resistance are studied by using a monoslope roof tested Florida International University's Wall Wind Experimental Facility. Results from both aerodynamic assessment test protocols showed that near upper corners were subjected high suctions due cornering winds. This presents critical loading case for which shingle systems not typically standard tests. Moreover, extent permeability underneath was observed vary with spatial location direction. Finally, comparison area-averaged Cp values obtained study GCp plots ASCE 7-16 Standard provisions, do consider permeable (e.g., shingles), can underestimate on shingles.
