Book excerpt: A study was made of the effectiveness of the surrounding soil in restraining the lateral movement of shallow-buried arches subjected to blast overpres ures from a nuclear explosion. The theory is developed for parabolic arches with circular or barrel arches included as a special case. It can be pplied equally well to arches oriented with their longitudinal axes perpendicular to or parallel to the direction of travel of the blast wave. The arch is considered to be buried near the surface of a semi-infinite soil mass. The depth of cover over the crown is limited to one-half of the arch span. The twohinged rather than the fixed arch is selected as representing more closely the shallow-buried rch structures used in full-scale nuclear tests to date. While these structures were not actually pinned at the arch abutments, their behavior under blast loading appears to resemble more closely the pinned th n the fixed case. he principal variables studied in the numerical examples include: (1) depth of cover, (2) overpressure loading, (3) arch material, and (4) arch span.

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.

Book excerpt: It was evident that the passive pressures which developed on the sides played the dominant role in providing resistance. It has been found that in static tests some of the surface load is carried by arching through the soil. In the dynamic tests the inertial forces of the soil above the arch were found to be important. The inertial load overcame the soil shear resistance so that a load approximately equal to the surface load acted on the structure. A model analysis of the system and subsequent comparison of the deflections from the small-structure tests and the Operation Plumbbob Structure 3.3 tests indicate that modeling of deflections is possible.

Book Synopsis Similitude Study of Flexible Buried Arches Subjected to Blast Loads by : Jimmy P. Balsara
Download or read book Similitude Study of Flexible Buried Arches Subjected to Blast Loads written by Jimmy P. Balsara and published by . This book was released on 1968 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).
Book Synopsis Predicting Blast-induced Body Motions of a Buried Structure with Footings by : Jay R. Allgood

Available in PDF, EPUB and Kindle. Book excerpt: An approximate theory is presented for predicting the absolute and relative body deflections of shallow-buried shelters in order to provide the designer with a rational approach for selecting footing dimensions. The theory consists of two coupled parts, one that describes the motion of the free field and another that defines the motion of a model of the structure, its foundation, and the covering soil. The soil characteristics are represented by straight-line approximations to the loading and unloading portions of the stress-strain diagram from a one-dimensional compression test. Incremental strains are integrated as the stress wave propagates downward to obtain the absolute free-field displacement at the elevation of the footings. Motion of the structure is represented by a single-degree-of-freedom analog. Empirical functions are used to represent footing reaction and arching in the model of the structure. These functions are incorporated in the differential equation of motion, which is solved with the aid of a digital computer. The results are compared with available test data; velocities and deflections agree reasonably well but the magnitude of the peak accelerations from the theory are larger than the corresponding measurements. Computations performed with the computer code indicate that surface loads above about 100 psi cannot be resisted if the maximum relative deflection between the footing and the floor slab is limited to 2 inches.
