Abstract : The objective of this research was to validate the analytical design model for determining the effectiveness and feasibility of a sheet retrofit. This report focuses on a polypropylene sheet as the retrofit material for validating the mechanics of the model and includes an informed and accurate design methodology for blast retrofit of CMU infill walls. The model was developed to be material independent, and the engineering level calculations can be completed, if the stress versus strain response of the material is known.
