| Abstract | Adhesive Applied Roofing Systems (AARS) are compact roof systems that use cold adhesives to integrate their components. Differences in adhesive types and method of applications can influence the wind uplift performances of AARS. Full scale experimental studies have been conducted and it revealed that majority of failures occurred at the insulation level and its interface. Based on this observation, a simplified three-dimensional finite element (3D-FE) model is developed to assess the uplift resistance of AARS. However, at this stage, the modeling simulation does not incorporate the studies due to the independency effects (e.g. # of meshes, # of elements and type). The model is assumed as isotropic elastic materials consisting of three parts (insulation, adhesive and insulation). To benchmark the model, new testing specimens were fabricated and tested. The results showed good agreement in comparison with the model. Using the benchmarked model, the effects of the adhesive thickness and its methods of application were investigated. Overall stresses distributions were computed at each level of the models as an indicator of AARS performances. This paper presents the results from this ongoing numerical study. |
