Blast Door Construction Tests

The goal of these tests was to characterize the behavior and performance of various configurations of skin-core construction methodologies used in full-sized blast-resistant steel doors. A total of 18 static beam-assembly tests were conducted, which consisted of the flexural four-point bending of door segments, to inform on the performance characteristics of full-sized blast resistant doors. Six tests were conducted to evaluate the effectiveness of three skin-core construction methodologies, which consisted of one epoxy and two weld attachment specifications, between door skins and their internal reinforcing structures. The remaining 12 tests were performed to evaluate the in-situ performance of hinge hardware typically installed on blast resistant door assemblies. The results of the skin-core construction tests demonstrated that closely spaced weld patterns would provide the best blast performance. The results of the hinge hardware tests demonstrated that hinges which provided a continuous load-path directly into the primary structural core elements of the door frame and door were ideal; furthermore, robust hinges with fully-welded or continuous knuckles were best suited for limiting undesirable deformations.
