Available in PDF, EPUB and Kindle. Book excerpt: The determination of the loads on and behavior of shallow-buried arch structures is complicated by the geometry of the arch and by existence if soil structures arches interaction effects. A common approach to the analysis of buried is to idealize the structure as a lumped parameter single degree of freedom (SDOF) system. The parameters which must be assumed for input into the SDOF model include a loading function and a structural resistance deflection relationship. The applied load on a buried arch due to overpressure at the ground surface includes a radial and a tangential component. The radial component can be measured experimentally; however, there seems to be no available transducers to measure the tangential component or interface friction. Two 1/12-scale model reinforced concrete arches were tested statically in a sand backfill. The arches were semicircular with an inside radius of 1 foot 9 inches and a thickness of 2 inches. One arch was covered with two layers of 1/32-inch-thick Teflon at the soil-structure interface to significantly reduce the interface friction, and the loading and behavior of the two arches were compared. Pretest finite element calculations were conducted to estimate the arch behavior. Based on both the experimental data and posttest calculations, it appears that interface friction on a shallow buried arch has an effect on its behavior, at least for the case of static loads. The load path at sections in the arch with a lower friction coefficient at the interface tended more toward pure compression than it did in the other arch.

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.

Available in PDF, EPUB and Kindle. Book excerpt: A damped single degree-of-freedom model was developed to represent the gross dynamic behavior of shallow buried reinforced concrete arches subjected to specified nonuniform pressure distributions. Structural parameter were developed for a generic structure based upon available information in the literature and first principal calculations. Values of maximum crown deflection, calculated from numerical integration of the differential equation of motion, were compared with similar results from field experiments. Results utilizing structural parameters selected on this basis of the recommendations in this study provide the best agreement. (Author).

Download or read book Static Loading of Small Buried Arches written by H. L. Gill and published by . This book was released on 1964 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Static and dynamic tests have been performed to study the behavior of small buried arches. The objective was to gain information which will serve as a guide in developing design methods for underground structures. This report describes the static tests, the prime purposes of which were: (1) to obtain information on the behavior of a statically loaded soil-arch system, and (2) to provide data for comparison with that from a similar system subjected to blast loading. The test configuration consisted of two conterminous semicircular arches each 30 inches in diameter buried in dry sand with 6 inches of cover over the crown. The arches were identical except for differing footing widths. The entire system was contained by the NCEL atomic blast simulator pit, which is 9 feet by 10 feet in plan and 12 feet deep. Static loads up to 25 psi were applied to the surface of the sand as various measurements were being made. The test results show that the expected decrease in footing deflection with increase in footing width was accompanied by an increase of maximum moment in the arch. (Author).
