Book Dynamic Test of a Model Flexible arch type Protective Shelter

Download or read book Dynamic Test of a Model Flexible arch type Protective Shelter written by Thomas E. Kennedy and published by . This book was released on 1967 with total page 124 pages. 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 Model Study of the Response of Silo type Structures in Dry Sand Under One dimensional Plane Wave Loading

Download or read book Model Study of the Response of Silo type Structures in Dry Sand Under One dimensional Plane Wave Loading written by Edward Belk Perry and published by . This book was released on 1973 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Froude modeling, where strength and modulus properties and surface overpressure scale as the length scale, is a potential method for determining the structural response of underground protective structures at overpressures in excess of existing laboratory devices provided the strength and modulus properties can be adequately scaled. The results of this study indicated that Froude model tests on silo-type structures in dry sand under one-dimensional plane wave loading could predict the loading response of a prototype constructed using a length scale of three. The primary contribution of this study was to focus attention on the necessity of scaling the unloading soil moduli if Froude modeling is to successfully predict the time-history of a soil-structure system whenever the characteristics of the problem (loading, geometry, etc.) are such that unloading occurs in the soil.

Book The Elastic Response of Buried Cylinders in Sand

Download or read book The Elastic Response of Buried Cylinders in Sand written by Robert Evans Walker and published by . This book was released on 1966 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of the study indicate that there are certain regimes where the elastic theory could be used to determine the dynamic magnification factors. Further, elastic theory does not appear to be applicable over the entire pressure domain nor does it appear to predict the location of the maximum strain. A majority of the observed phenomena may be explained by the fact that the static transmissibility of the soil increases in higher pressure regions and by the fact that the dynamic transmissibility is higher than the static for the low pressure regions. Both the static and dynamic transmissibilities seem to converge in the higher pressure regions. (Author).

Book Behavior of Flexible Cylinders Buried in Sand Under Static and Dynamic Loading

Download or read book Behavior of Flexible Cylinders Buried in Sand Under Static and Dynamic Loading written by Gayle E. Albritton and published by . This book was released on 1968 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The general objective of the investigation was to study experimentally the behavior to failure of flexible, horizontally oriented cylinders buried at various depths in dense, dry sand and subjected to either static or dynamic surface overpressures. Static and dynamic tests were conducted on 33 different cylinders, fabricated of high-yield-strength aluminum. Results indicated that collapse of the cylinders occurred while the strains in the cylinder walls were still in the elastic range. The cylinders buried at the shallow depths (zero to one-half cylinder diameter above the crown) collapsed by a catastrophic snap-through or caving of the crown. For the cylinders buried at depths of three-quarters to two cylinder diameters above the crown, the mode of collapse was an instantaneous elastic buckle that occurred at the spring line or invert of the cylinder. The collapse mode of the cylinders under dynamic overpressure was similar to that of the cylinders collapsing under static overpressure. The results of the investigation verified the applicability of an equation for predicting the static collapse overpressure for smooth-walled, horizontally oriented, buried cylindrical structures and entranceways. The hoop-compression theory was found to be applicable for analyzing the structural design to determine if the cylinder would collapse in the elastic range. (Author).
