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.

The objective of the study was to investigate and verify model-to-prototype scaling relations for blast loaded buried arches that respond both elastically and inelastically. Four geometrically similar, semicircular aluminum alloy arches with 4-, 8-, 12-, and 36-inch diameters were buried in dense dry sand and subjected to air-blast-induced loads on the surface. The tests were conducted at the Large Blast Load Generator located at the U.S. Army Engineer Waterways Experiment Station. The results of two series of tests, each consisting of 3 repeated shots, ranging from 70 to 300 psi, are presented. Within the range of parameters investigated, the scaling of the dependent variables were adequately verified. These variables included acceleration, velocity, displacement, thrust, and bending moment. (Author).

Here is the second revised and updated edition of probably the most practical sourcebook on similarity methods and modeling techniques available. Written by leading authorities who incorporate many of the latest advances in the field, this new work maps out techniques for modeling as well as instrumentation and data analysis for an extremely wide array of problems in engineering dynamics. This practical reference uses experimental test data on various engineering problems demonstrating exactly how and why these similarity methods work. The problems involve spread of oil slicks, explosive cratering, car crashes, space vehicle heat exchange, explosive forming, and more. The spectrum of topics covered and number of examples are far greater than in other texts. Of particular importance are the dissimilar material modeling techniques which bring new versatility and freedom to the modeler in structural dynamics. The book also contains a clear, in-depth discussion of the theory underlying modeling and includes alternate methods for developing model laws. The work will undoubtedly prove invaluable to every professional involved in testing or design of dynamic experiments.
