Available in PDF, EPUB and Kindle. Book excerpt: Operation Prairie Flat, a 500-ton TNT surface burst detonated at the Defence Research Establishment, Suffield, located near Medicine Hat, Alberta, Canada, provided the U.S. Army Engineer Waterways Experiment Station an opportunity to obtain data pertinent to the design of structures that can resist the effects of blasts from nuclear weapons. This test operation was a joint effort by the United States, Canada, and the United Kingdom in which there were 39 United States approved projects. The objective of Project LN314, discussed herein, was to investigate the dynamic response of a 1/2-scale model of a flexible-arch troop shelter when subjected to the blast effects of a surface burst. Specific objectives were to (1) determine the gross motion of the structure with particular emphasis on the response of the footings, (2) determine thrust and moment relations at various sections of the structure, and (3) obtain response data from a field test for correlation with similar data from laboratory simulation tests. A 1/2-scale model was tested at a ground range of 400 feet and an over-pressure of 142 psi. This structure was buried in dense sand with the crown of the arch 2 feet (1/2 the radius of the arch) below the ground surface. The motion response was generally as expected, with approximately a 6-inch permanent vertical displacement. The transient measured response compared very well with that predicted, based on laboratory model tests. The structure was uncovered after the test, and it was observed that no major damage had been sustained by any structural components. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A method of analysis for buried arches with footings was developed to predict their response to a nuclear airblast overpressure. The method of analysis was formulated by considering the arch ring as a discrete model consisting of a finite number of nodes (flexible joints) connected by rigid bars initially of equal length. The results of laboratory and field tests on 1/4.5- and 1/2-scale models, respectively, of an arch structure are compared with predictions made using the analysis. Arch internal loads, footing motions, and free-field motions are compared with those predicted by the analysis and compare favorably. The analytical technique was used to predict the response of the prototype structure to a 140-psi air overpressure loading resulting from the detonation of 10-kt, 100-kt, and 1-Mt weapons, to a 100-psi air overpressure for a 1-Mt weapon, and to the Operation Prairie Flat (500-ton TNT) 140-psi overpressure and the predicted response was compared with that assumed in designing the structure. The method of analysis developed is recommended whenever a significant cost savings can be realized because a number of structures are to be constructed or when local soil conditions make design by cruder methods uncertain.
