National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

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.
