Available in PDF, EPUB and Kindle. Book excerpt: Three pneumatic tires were used in a laboratory study to compare the performance of dual wheels at zero spacing with the performance of single wheels and to determine the influence of tire spacing on dual-wheel performance. One-pass tests were conducted on air-dry, medium dense to very dense sand. The data were analyzed for powered wheels in terms of pull, torque, and sinkage coefficients and of efficiency, all at 20 percent slip, and for towed wheels in terms of towed force coefficients. The existing WES performance prediction system was used in both cases. Results showed that a powered dual wheel at zero spacing, considered as two wheels sharing equal load and exhibiting equal performance, outperformed a single wheel with the same characteristics as each wheel of the dual-wheel configuration. The performance of powered dual wheels decreased with increasing wheel spacing until the two wheels performed like single wheels. This critical spacing was reached when it became two to three and one-half times the width of one of the wheels. A dual wheel at zero spacing, considered as one wheel, performed practically the same as a single wheel with the same characteristics of the dual-wheel configuration; however, the dual wheel with zero spacing performed more efficiently than the single wheel over a certain range of load, deflection, and soil strength combinations.

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.
