Available in PDF, EPUB and Kindle. Book excerpt: One-of-a-kind coverage on the fundamentals of foundation analysis and design Analysis and Design of Shallow and Deep Foundations is a significant new resource to the engineering principles used in the analysis and design of both shallow and deep, load-bearing foundations for a variety of building and structural types. Its unique presentation focuses on new developments in computer-aided analysis and soil-structure interaction, including foundations as deformable bodies. Written by the world's leading foundation engineers, Analysis and Design of Shallow and Deep Foundations covers everything from soil investigations and loading analysis to major types of foundations and construction methods. It also features: * Coverage on computer-assisted analytical methods, balanced with standard methods such as site visits and the role of engineering geology * Methods for computing the capacity and settlement of both shallow and deep foundations * Field-testing methods and sample case studies, including projects where foundations have failed, supported with analyses of the failure * CD-ROM containing demonstration versions of analytical geotechnical software from Ensoft, Inc. tailored for use by students in the classroom

Available in PDF, EPUB and Kindle. Book excerpt: Drilled shafts have been used on a limited scale for many years as an alternative to driven piles in a variety of foundation problems. However, uncertainty about the behavior of the drilled shaft has forestalled widespread adoption. The subject package, by Dr. Lymon C. Reese of the University of Texas, is intended for use by bridge engineers, geotechnical engineers, and builders of pile foundations. The manual contains rational procedures and practical guidelines for the design and construction of drilled shaft foundations. Volume I presents a rational design procedure for drilled shafts under axial loading and includes guidelines on construction methods, inspection, load testing, specifications, and cost estimates. Volume II presents alternative methods for computing the response of the shaft to lateral loading and presents the structural design of the shaft for axial and/or lateral loading.

Available in PDF, EPUB and Kindle. Book excerpt: Dimensional analysis of deep foundation side resistance is used to formulate the laws of similitude for drilled shaft uplift capacity. The resulting prediction equation for dimensionless side resistance then is tested against the results of static uplift load tests on model drilled shaft foundations in sand constructed at three different scales, all satisfying the same conditions of similitude. The test results and analysis of soil response show that soil dilation, constant thickness of the soil shear zone surrounding the shaft regardless of shaft diameter, and curvature in the Mohr-Coulomb failure envelope at low normal stresses can combine to cause apparent scale effects. These mechanisms are isolated and evaluated quantitatively for the shafts of this study, and apparent scale effects are eliminated by applying correction factors to the load test results. The factors illustrated by this study are used to develop guidelines for: (1) conducting model load tests to avoid scale effects and (2) developing correction factors for small-scale models that may be affected by apparent scale effects.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Drilled shaft foundations are primarily used to support structures such as bridge piers, towers, buildings, transmission towers, and roadway median cable barriers. Generally, the main characteristics of drilled shafts are to transfer the loads to the stronger subsoil layers in the vertical direction and also their ability to withstand lateral movements from lateral loads applied. Though the design of shafts is well established with respect to combinations of loads and moments, their behavior under pullout type inclined loading is not well established. The inclined load applied is the combination of lateral and uplift loads applied at the same time and structures such as ends of cable barriers and transmission towers that are supported by the drilled shafts. This dissertation research mainly focuses on the use of drilled shafts supporting at the ends of the cable median barrier systems. These shafts play an important role in protecting the integrity of the cables thereby reducing cross-over collisions at highway medians. Several foundation problems were recorded in north Texas when drilled shafts were used to connect all the cables of the cable barrier systems. During December 2006 to February 2007, several foundation failures of three cable median barrier were observed in Kaufman County near Dallas without any traffic related vehicular impacts (Heady, 2008). Preliminary investigation of foundation failures showed that failed drilled shafts were located in a high plasticity clay environment. Causes of failures are attributed to cold temperature induced shrinkage in the cables that might have significantly increased the tensions in them. Other factors consist of soil saturation from prolonged rainfall events and also potential use of smaller size drilled shafts at the site. In order to fully understand the causes of failures, the present dissertation research was performed. As a part of this research, various sizes of drilled shafts were designed and constructed in a clayey soil environment similar to the one where foundation distress was observed. Geotechnical sampling and laboratory testing were performed and the test results showed different soil layers including high plasticity clayey soil near the ground surface. Soil strength properties for both unsaturated (field condition) and saturated conditions were determined and these results are used in the analysis of field test results to deduce the causes of foundation distress. A new load test setup for the application of an inclined tensile loading on the drilled shaft was designed to simulate the natural field loading condition exerted by the cables. The capacities of different sizes of drilled shafts from field test were tested and measured with this setup and these results showed that the dimensions of reaction test piers and spacings used between reaction and test piers have yielded results that are not influenced by the boundary effects or reaction shaft movements. All load tests were conducted until the foundations reached failure. Test results were analyzed with both uplift capacity and lateral capacity analyses models proposed by many researchers as well as Finite Element Method (FEM) based numerical modeling in understanding the behaviors of drilled shafts under the inclined loading. After obtaining good simulation results, the analytical models are further used for various hypothetical foundation dimensions and for different undrained shear strengths of soils. These test results are used to develop foundation design charts for inclined loading conditions. Both the selection of a specific design chart and its use are explained. Additionally, drilled shaft construction guidelines for cable barrier systems and recommendation for periodic maintenance are provided.
