| Abstract | The objective of this study was to investigate the effects of wind fatigue on the seam strength of mechanically attached TPO systems. Conventional one side weld system and the new double side weld system was installed on the Dynamic Roofing Facility and subjected to the SIGDERS dynamic wind test protocol. The seam strengths before and after the wind test were determined. Seam samples failed cohesively in the polymer and had strength from 3.0 to 8.3 kN/m (17 to 47 lbf/in.). Wind fatigue caused a reduction of about 30% on the seam strength. Wind uplift rating of double side weld systems is better than that of the one side weld system. |
