Available in PDF, EPUB and Kindle. Book excerpt: The general objective of the pilot test reported herein was to determine the response of a small-scale, buried, flexible-arch troop shelter to a simulated nuclear blast overpressure. To accomplish this, a model structure was constructed using a scaling ratio of 1 to 4.5. The model structure was buried in dense, dry sand with depth of cover equal to one-quarter the diameter of the arch. The test was conducted in the Waterways Experiment Station Large Blast Load Generator at an overpressure of about 85 psi. Strain, acceleration, and deflection were measured at various points on the structure along with pressure in the free field and overpressure at the soil surface. The only serious damage observed was a shear failure of the bolt connections between the bulkhead columns and the end trusses. The results of this study will be used to plan further tests of the structure.

Book Synopsis Similarity Methods in Engineering Dynamics by : P.S. Westine
Download or read book Similarity Methods in Engineering Dynamics written by P.S. Westine and published by Elsevier. This book was released on 2012-12-02 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Failure of Footing-supported Buried Steel Arches Loaded Statically by : John F. Munn
Download or read book Failure of Footing-supported Buried Steel Arches Loaded Statically written by John F. Munn and published by . This book was released on 1970 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this investigation was to study the failure of statically loaded steel circular arches buried in sand as affected by three variables; footing width, arch flexibility, and depth of burial. Static tests were performed on 16 arches with 18-inch outside diameters. The parameters varied were wall thickness, depth of burial, and footing area. The maximum static overpressure available was 100 psi. Strain measurements were made at various locations on the arch so that thrusts and moments could be computed. (The computer program developed for these computations is described in Appendix B.) Measurements of crown deflection and footing settlement were also made. Three modes of failure were observed in the various tests. Buckling of the crown of the arch and punching of the footings into the supporting soil were the two dominant failure modes, but buckling of the arch haunches also occurred in the case of the thin arch with large footings. Generally, it was observed that the thin arches with large footings exhibited arch failure while the thick arches with small footings exhibited footing failure. Based on the test results, a method was proposed for predicting the type of failure occurring for arches with various footing and arch stiffness configuration combinations. Support investigations were conducted to determine the properties of the sand and steel used in the test. Sand properties are described in Appendix A. (Author).
