| Abstract | Wind dynamics, on a mechanically attached single ply roofing assembly, lift the membrane and cause fluttering, introducing stresses at the attachment locations. To identify the component of the system that has the weakest resistance against wind uplift forces, a dynamic method of evaluating roofing systems is beneficial. Each component in the assembly offers resistance to wind uplift. Failure occurs when the wind uplift force is greater than the resistance of any one or more of these links. This study presents data that will help roof system designers maximize wind uplift ratings by choosing the appropriate roof components at the early design stage or by replacing/adding components to improve wind uplift resistance during reroofing. By diagnosing the weakest link from the failure mode, one can improve the wind resistance of a system. Therefore, a series of Mechanically Attached Systems (MAS) were constructed and exposed to simulated dynamic wind uplift forces at the Dynamic Roofing Facility of the National Research Council Canada (NRC-IRC). The goal of the paper is to present the ongoing experimental program and answer the following questions: |
