Comments/Design Considerations -
This design is similar to 33-15-61, the DDESB approved Standard Freloc-Stradley
Magazine. 3-03-31 was designed for construction at VILSECK ASP-I (Germany) for USAFE. It measured 26' W X 80' L and had a ceiling height of 14' at the centerline. The entrance measured approximately 10' by 10'. It had a reinforced concrete arch of uniform thickness. a heavily reinforced headwall, and bi-parting, double-leaf steel doors. A Sep 1977 dynamic analysis of this Freloc design, performed by Agbabian Associates for the COE, European Division, determined that the headwall was sufficiently strong to meet NATO face-on loading criterion, but the door was not. Recommendations were prodded in Agbabian Associates Report R-7745-4503 to strengthen the doors by adding additonal horizontal and vertical stiffeners on the exterior side of the doors. DDESB-KT Memos of 27 Jan and 4 May 1978 states that the door of the ECM analyzed by Agbabian Associates (33-03-31) met U.S. standard magazine criteria.
