This book was released on 2011 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a simplified method to be used for evaluating the skin friction and tip resistance of axially loaded drilled shafts. A summary of literature and current practice was completed and then a comprehensive set of field and laboratory tests was performed. Several soil samples were collected from different sites from Arizona and surrounding states. Large scale direct shear apparatus was developed and used to determine the friction between soil and concrete. Finite element analyses were conducted on several prototype cases to determine effect of soil parameters such as dilation on the skin friction values. A step-by-step simplified approach was introduced to determine the skin and tip resistance of drilled shaft foundations in gravelly soils. An example application was presented to guide users in utilizing the simplified approach.

Book excerpt: This document was written as a resource for participants in a short course covering the topic of construction and design of drilled shaft foundations for bridges and other structures. It is the second edition of a Federal Highway Administration workbook on construction and design of drilled shafts. The first edition was written in 1988 (FHWA-SA-HI-88-042). While introductory material from the 1988 edition was retained, the emphasis in this document is on providing relatively comprehensive information for engineers who already have some experience with drilled shaft construction and/or design. The initial chapters cover an overview of the characteristics of drilled shafts, site investigations for drilled shafts (to collect information for both construction and design), and details of drilled shaft construction. These chapters are followed by several chapters on the design of drilled shafts in soil and rock for both axial and lateral loading, with examples. Both allowable stress design and load and resistance factor design principles are addressed. Details of design calculations procedures are provided in the appendices.

Download or read book Drilled Shaft Manual Construction procedures and design for axial loading written by Lymon C. Reese and published by . This book was released on 1977 with total page 152 pages. 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.

This book was released on 1984 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drilled shaft foundations are widely used in the construction of numerous types of permanent structures such as buildings, residence, bridges, and towers in unstable materials and fills including swelling soils. Much research has been done to develop design procedures for drilled shaft foundations, but few comparisons had ben made to validate the design methodologies for different soils and loading conditions. This report presents a comprehensive evaluation of different design procedures and describes those procedures that offer satisfactory solutions to the design of shaft foundations. Guidelines are provided for the design and construction of drilled shaft foundations subject to axial and lateral loading forces using either effective or total stress analysis.

Book excerpt: Since the early twentieth century, the implementation of drilled shafts has transformed the face of foundation design of bridges and buildings (Grader 2012). These major components of foundations began in the 1920’s near the Great Lakes area of Chicago and have been competing with driven pile technique since the 1960’s (Coduto 2001). Currently, drilled shafts are more implemented with major bridge constructions and building projects (Brown 2007). With the popularity of both drilled shafts and driven piles, each come with a set of advantages for each. Drilled shafts appear to be the most cost effective option to operate the equipment necessary for completion, and they give the ability to change the diameter or shaft length to address the unforeseen changes in soil conditions which are be monitored during the drilling process. Drilled shaft processes have demonstrated the ability to penetrate through soils containing cobbles and boulders and thus give the ability to be socketed into bedrock. During the construction process, drilled shafts reduce the high noise level and vibration compared to that with driven piles. Driven piles, however, have some advantages; for example, driven piles allow for consolidation of soils laterally along the pile length and the tip together. This consolidation allows for the increase in the effective stress of the soil, that can increase skin friction and end bearing factors. The driven piles also give redundancy to the foundation system; where drilled shafts may have one massive pile, a driven pile system will have many piles (Coduto 2001). While using the considerations and ideas mentioned previously, the purpose of this study is to use a soil-pile interaction with a non-linear finite element model in connection with an advanced optimization method with which to develop the most economical drilled shaft design. The application of a non-linear finite element model in consideration with an advanced optimization method and various FORTRAN coded soil characterizations has not been determined to be the best economical drilled shaft design. Therefore, this study required a different direction and consideration than was used before. Also, this report does not reflect long-term analysis of drilled shafts. However, a short-term analysis is considered to be the controlling condition. A long-term analysis of the drilled must be completed to determine the critical condition.
