Abstract: The objective of this test program was to determine the vulnerability of two different types of metal end walls designed for attachment to a buried personnel shelter made of corrugated structural steel. One end wall was designed and fabricated by the Republic Steel Corporation of Youngstown, Ohio. It was a revision of a design previously tested at WES. The other end wall evaluated was designed and fabricated under the direction of the U. S. Naval Facilities Engineering Command, Washington, D. C. Both end walls were assembled and tested at the WES Big Black Test Site. They were subjected to the blast effects from 16-pound spheres of TNT (equivalent to the explosive effects of 155-mm artillery shells) detonated in close proximity to the end walls. From a comparison of the results of the end-wall tests based on ease of erection and strength characteristics, it is believed that the revised Republic Steel end wall is more compatible for use with a multiplate pipe-arch structure.
