This book was released on 2010 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides recommendations to revise the AASHTO LRFD Bridge Design Specifications relating to the distribution of live load to buried structures. The report details the development of simplified design equations (SDEs) for structural response based on three-dimensional (3D) analysis of 830 buried culverts. In addition, the report provides guidelines for conducting 2D and 3D modeling for design situations with conditions not covered by the SDEs. The material in this report will be of immediate interest to roadway and bridge designers.

Available in PDF, EPUB and Kindle. Book excerpt: Buried pipes are a highly efficient method of transport. In fact, only open channels are less costly to construct. However, the structural mechanics of buried pipes can be complicated, and imprecisions in the properties of the soil envelope are usually too great to justify lengthy, complicated analyses. Designers and engineers need principles and m

Available in PDF, EPUB and Kindle. Book excerpt: The objective of the study was to investigate the elastic response of a stiff, horizontally oriented, steel cylinder backpacked with a low-strength cellular concrete and buried in a dense, dry sand, whose surface was subjected to static and dynamic overpressures. Four series of tests were conducted on the cylinder (one static and one dynamic series without backpacking, and two dynamic series with backpacking). The cylinder had an outside diameter of 6 inches, a 0.120-inch wall thickness, and a stiffness of 164 psi. Static and dynamic surface overpressures ranged from 0 to 250 psi and from 100 to 250 psi, respectively. In the tests with backpacking, a layer of cellular concrete with a thickness of either 1-3/8 or 2-7/8 inches encompassed the cylinder. The cylinder was buried at a depth of 15 inches, which was held constant for all tests. Measurements were made of the strains and accelerations experienced by the cylinder, test chamber bonnet pressure, surface overpressure, and free-field pressure and acceleration. Backpacking reduced the peak strains experienced by the cylinder, and a redistribution of the strains in the cylinder occurred. For all tests utilizing backpacking, the accelerations of the cylinder were reduced to approximately 10 to 50 percent of those measured in corresponding tests without backpacking. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general review of the literature on underground structures, combined with new specifications, engineering case studies, and numerical simulations based on the authors’ research. It focuses on the basic concepts, theories, and methods of the design of underground structures. After an introduction, it covers various topics, such as elastic foundation beam theory and numerical analysis methods for underground structures, as well as the design of shallow underground structures, diaphragm wall structures, shield tunnel structures, caisson structures, immersed tube structures, and integral tunnel structures. It also includes tables for calculating elastic foundation beam. This book is intended for senior undergraduate and graduate students majoring in urban underground space engineering, building engineering, highway engineering, railway engineering, bridge and tunnel engineering, water conservancy and hydropower engineering.

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).
