Available in PDF, EPUB and Kindle. Book excerpt: An approximate method is developed for predicting the deflections of the footings of a buried arch subjected to a blast wave traveling along the surface. Results from the theory are compared with measured values from Operation Plumbbob Structure 3.3a. The influence of the dominant parameters is discussed. It is shown that duration of loading is exceedingly important in governing the magnitude of footing deflections. The theory is presented in a form suitable for use in the design office. (Author).

Book Synopsis Blast Loading of Small Buried Arches by : Jay R. Allgood

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.

This book was released on 1961 with total page 486 pages. Available in PDF, EPUB and Kindle. 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.

Book Synopsis Predicting Blast-induced Body Motions of a Buried Structure with Footings by : Jay R. Allgood
Download or read book Predicting Blast-induced Body Motions of a Buried Structure with Footings written by Jay R. Allgood and published by . This book was released on 1967 with total page 64 pages. 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.
