2018 NDIA IESSE ECM’s Vertical Seismic Ground- Motion Effects page 1
Earth Covered Magazines Vertical Seismic Ground Motion Effects
Parsons – Harold Sprague and Jonathan Shull
Abstract:
Earth covered magazines (ECMs) are designed to contain explosives and weapons. Standard
ECM designs were developed to provide a high degree of safety for explosives and weapons
storage. The lead agency responsible for the development of ECMs has been the Defense
Department Explosive Safety Board (DDESB). The DDESB’s focus has been mitigating
sympathetic detonations and limiting damage caused by an accidental detonation of the
contents of an ECM. The U.S. Army Engineering and Support Center – Huntsville Environmental
and Munitions Center of Expertise (EM CX) serves to provide standard designs for ECMs that can
be constructed with minimal field adaptation. The EM CX has also further developed the
standard ECM design. Unified Facility Criteria (UFC) 3-301-01 provides criteria for seismically
induced ground motions. UFC 3-301-01 refers to American Society of Civil Engineers (ASCE) 7 to
provide more detailed requirements for the design of structures including ECMs. Typically, an
ECM is designated as Risk Category (RC) III. ASCE 7-16 included vertical ground accelerations for
consideration. Vertical ground accelerations produce a significant risk of failure in the event of
an earthquake. This paper’s goal is to define the risk to ECMs from earthquake ground motions.
