Abstract: A new line of blast-resistant steel doors was developed at the University of Ottawa for a local manufacturer through combined experimental and analytical research. The main objective was to develop blast-resistant steel doors meeting performance levels required for the minimum anti-terrorism marketplace. The University of Ottawa’s Shock Tube Testing Facility was used to subject full-scale blast doors to simulated shock waves. The full-scale blast tests were conducted to determine the response of the blast doors relative to ASTM F2927 door and glazing classifications. A number of parameters affecting door response were considered, including door aspect ratio, construction methodology, door-frame construction, as well as anchor size and quantity. The experimental portion of the study was complimented by an analytical investigation to develop door design tools. Finite element analysis was employed to generate door resistance curves. This was followed by single-degree-of-freedom dynamic analyses to predict the various levels of protection for the blast scenarios studied. This paper presents a general overview of the approach adopted for the experimental and analytical investigations. Details of a variable geometry test fixture, capable of accommodating a range of door sizes and anchor configurations, are presented. The experimental test procedure as well as test results are discussed. Analytical work to predict door response, and a summary of key design considerations, are discussed.
