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.

Available in PDF, EPUB and Kindle. Book excerpt: The investigation reported herein was undertaken to develop an approach to modeling displacements of surface and shallow-buried footings on dry sand subject to high-intensity, single-pulse loads. A hypothetical shallow-bured structure with an isolated footing loaded by airblast overpressure produced by detonation of a nuclear weapon was assumed for design of load pulses on nine model footings used: footing widths of 4.5, 6.0, and 7.5 in. and depth-of-burial to footing width ratios of 0, 0.5, and 1.0. The principles of similitude were used to scale length, force, and time in the models. The models were placed in mobile test bins of uniform, fine, dry sand (90 percent relative density) and subjected to dynamic and static loading. Nondimensional load-displacement relations dependent only on depth-of-burial ratio were developed relating maximum displacement to peak dynamic load, footing width, and soil shear strength gradient. When the dynamic response of the footings in the form of reaction-displacement curves was compared with static response, an increase in initial stiffness and ultimate strength was observed for dynamic loading. However, these dynamic increases were greatest when the static shear strength was lowest, i.e. footings on the surface, and were least for footings buried at a depth equal to its width where the static overburden produced a substantial increase in shear strength.

This book was released on 1968 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were performed on aluminum cylinders 4 inches in diameter and 2 feet long buried vertically with their top at the soil surface in 20-30 Ottawa sand and in Goose Lake clay with a water content of approximately 18 percent. Static and dynamic pressures were applied to the soil surface. In all tests the test cylinder was floating in soil contained in a cylindrical vessel 2 feet in diameter and 5.12 feet deep. For static loadings in sand there was a definite tendency for the ratio of horizontal to vertical pressure on the test cylinder, K sub s, to become smaller with depth and to remain fairly constant with pressure. These tests show that the change from downward shear to upward shear occurs near the lower one-third point of the test cylinder. Static tests in clay gave a wide range in K sub s from approximately 0.25 to 1.0 though arguments are presented which indicate that it should be near 1.0 for all the tests. Shear reversal appears to have occurred near midheight of the test cylinder in the dynamic clay tests also. (Author).
