Abstract : Six small buried arches were subjected to blast loads from a nuclear explosion to provide information on their structural behavior. The principal objectives were to determine the effect of a traveling blast wave on arch response and to check model scaling relationships. It was determined that the traveling wave caused arch response in the first antisymmetrical mode, which was superposed on response in a symmetrical mode. The relative importance of the response in the antisymmetrical mode was not determined. The scaling relationship for overpressure was found to be unity. Information on thrusts, moments, accelerations, pressures, deflections, and arching is also presented.
