An understanding of the mechanical properties of unsaturated soils is crucial for geotechnical engineers worldwide, as well as to those concerned with the interaction of structures with the ground. This book deals principally with fine-grained clays and silts, or soils containing coarser sand and gravel particles but with a significant percentage of fines. The study of unsaturated soil is a practical subject, linking fundamental science to nature. Soils in general are inherently variable and their behaviour is not easy to analyse or predict, and unsaturated soils raise the complexity to a higher level. Even amongst practicing engineers, there is often lack of awareness of the intricacies of the subject. This book offers a perspective of unsaturated soils based on recent research and demonstrates how this dovetails with the general discipline of soil mechanics. Following an introduction to the basic soil variables, the phases, the phase interactions and the relevance of soil structure, an up-to-date review of laboratory testing techniques is presented. This includes suction measurement and control techniques in triaxial cell testing. This is followed by an introduction to stress state variables, critical state and theoretical models in unsaturated soils. A detailed description of the thermodynamic principles as applied to multi-phase materials under equilibrium conditions follows. These principles are then used to explore and develop a fundamental theoretical basis for analysing unsaturated soils. Soil structure is broken down into its component parts to develop equations describing the dual stress regime. The critical state strength and compression characteristics of unsaturated soils are examined and it is shown how the behaviour may be viewed as a three-dimensional model in dimensionless stress-volume space. The analysis is then extended to the work input into unsaturated soils and the development of conjugate stress, volumetric and strain-increment variables. These are used to examine the micromechanical behaviour of kaolin specimens subjected to triaxial shear strength tests and lead to observations not detectable by other means. Unsaturated Soils: A fundamental interpretation of soil behaviour covers a rapidly advancing area of study, research and engineering practice and offers a deeper appreciation of the key characteristics of unsaturated soil. It provides students and researchers with a framework for understanding soil behaviour and demonstrates how to interpret experimental strength and compression data. provides engineers with a deeper appreciation of key characteristics of unsaturated soils covers a rapidly advancing area of study, research and engineering practice provides students and researchers a framework for understanding soil behaviour shows how to interpret experimental data on strength and compression the limited number of books on the subject are all out of date

Guide to evaluating design wind load to BS 6399-2:1997
Author: C.G. Bailey
This publication presents guidance on the use of the design procedures given to BS6399-2: 1997. Loading for buildings. Code of practice for wind loads, to calculate the wind loads on buildings, using methods that are suitable for hand calculations. These procedures include the Standard Method and Hybrid Method, which are presented in the code.
First published in 1984, Limit Analysis and Concrete Plasticity explains for advanced design engineers the principles of plasticity theory and its application to the design of reinforced and prestressed concrete structures, providing a thorough understanding of the subject, rather than simply applying current design formulas.
Updated and revised throughout, Limit Analysis and Concrete Plasticity, Third Edition adds—
* Reinforcement design formulas for three-dimensional stress fields that enable design of solid structures (also suitable for implementation in computer-based lower bound optimizations)
* Improved explanations of the crack sliding theory and new solutions for beams with arbitrary curved shear cracks, continuous beams, lightly shear reinforced beams and beams with large axial compression
* More accurate treatment of and solutions for beams with circular cross-section
* Applications of crack sliding theory to punching shear problems
* New solutions that illustrate the implication of initial cracking on load-carrying capacity of disks
* Yield condition for the limiting case of isotropically cracked disk
The authors also devote an entirely new chapter to a recently developed theory of rigid-plastic dynamics for seismic design of concrete structures. In comparison with time-history analyses, the new theory is simpler to use and leads to large material savings. With this chapter, plasticity design methods for both statical and dynamical loads are now covered by the book.

Fundamentals of Materials Science and Engineering: An Integrated Approach
Author: William D. Callister, David G. Rethwisch | Size: 26.23 MB | Format:PDF | Publisher: Wiley | Year: 2008 | pages: 912 | ISBN: 978-0470125373
Callister and Rethwisch’s Fundamentals of Materials Science and Engineering third edition continues to take the integrated approach to the organization of topics. That is, one specific structure, characteristic, or property type at a time is discussed for all three basic material types—viz. metals, ceramics, and polymeric materials. This order of presentation allows for the early introduction of non-metals and supports the engineer’s role in choosing materials based upon their characteristics.

Nonconventional Concrete Technologies Renewal of the Highway Infrastructure
Author: Committee on Nonconventional Concrete Technologies | Size: 5.88 MB | Format:PDF | Publisher: National Academy Press | Year: 1996 | pages: 125 | ISBN: 0-309-05687-X
This study was exciting because it challenged experts in a variety of fields to cross intellectual boundaries and think innovatively about concrete technology. The experts agreed to undertake this challenge for no reason other than their own intellectual curiosity and their desire to aid the development of new infrastructural materials and techniques. The committee is grateful for all the help it received and expresses its thanks to everyone who participated. Without the patience and support provided by many individuals and organizations, this report could never have been completed. In particular, the committee thanks Herbert A. Franklin of Bechtel Corporation. His support as technical advisor to the committee was invaluable. He provided great insight and made significant contributions to the report. Harold Jabloner of Hercules, Incorporated, and Youjiang Wang of the Georgia
Institute of Technology should also receive special thanks for their participation and insight while working with the committee. The committee is grateful for the dedication of Richard A. Livingston of the Federal Highway Administration for his vision and assistance to the committee. Jeff W. Rish of Wright Laboratories also provided valuable insight. This study relied heavily on the information collected from a range of materials-science experts at an international workshop that the committee organized. The committee is grateful to all of the participants, who provided the balance of expertise, insight, and originality needed to develop and scrutinize ideas about potentially new and innovative nonconventional concrete technologies. A complete list of workshop participants can be found in Appendix A

Does someone have the original copy of "Mechanics of Materials by James Gere - 6th edition"? Could i request for it. I bought the hard copy of "mechanics of materials by gere & timoshenko 4th edition". I wanna compare the 6th edition and 4th edition difference.
Thanks in advance.
