Steel Tips: Design of Special Concentric Braced Frames (2004)
Author: Michael L. Cochran and William C. Honeck | Size: - MB | Format:PDF | Quality:Unspecified | Publisher: Structural Steel Educational Council | Year: 2004
This document is very helpful in regard of large span steel structures, where most of the connections are of the subject type.
Connections are among the most essential parts in precast structures. Their performance relates to
the structural limit states, as well as to manufacture, erection and maintenance of the structure itself.
Proper design of connections is one major key to a successful prefabrication.
The literature on this matter mostly illustrates classical solutions, often well known, but an
explanation of a general design philosophy for the design of connections was necessary. In fact, the
engineer, confronted with particular problems in his daily practice, does not always have the
theoretical basis to find the most appropriate solutions.
Aiming at filling this gap, Commission 6 “Prefabrication” formed a Task Group – TG 6.2 – who
finally drafted this Guide to Good Practice. Its philosophy focuses on the knowledge of the behaviour
of a whole structure, of the mechanisms and paths of force transfer within the connections and of their
interaction with the structural members. Indeed, such knowledge is the base for assessing the safety
and reliability of usual types of connections and to develop innovative design.

~ Designed to give engineers a crash course in all aspects of modern geotechnical and foundation engineering
~ Takes readers step-by-step through the typical process of a design project--from proposal-writing to the final preparation of the "as built" report
~ Includes numerous visual aids: photographs, charts, tables, and more than 350 illustrations
From the Back Cover :
Improve your engineering design potential by mastering the practical aspects of modern geotechnical and foundation engineering. This book takes you step by step through the typical process of a design project--from the initial writing of a proposal for engineering services to the final preparation of the "as built" report upon completion of the project. This easy-to-understand reference places special emphasis of the visual aspects of geotechnical and foundation engineering, while minimizing the use of complex and theoretical analyses. Included are lots of photographs, figures, charts, and tables that show you exactly how today's design and construction methods and procedures are actually applied. You'll get the expertise required to: develop a complete program of geotechnical investigation; deal with geotechnical field and laboratory studies; analyze geotechnical data and engineering computations; carry out an engineering evaluation of construction; prepare and evaluate geotechnical reports. Whether you're an engineer or construction professional, this guide will give you the full range of methods, visual aids, examples, and simplified equations and calculations needed to handle any geotechnical project with complete confidence! Get detailed coverage of all major geotechnical and foundation topics: proposals; field exploration; laboratory testing; settlement of structures; bearing capacity; expansive soil; slope stability; earthquakes; erosion; deterioration; unusual soil; retaining walls; groundwater and moisture migration; grading; constructions services; reports.

After completing his Bachelors and Masters degrees in Civil Engineering at Villanova specializing in Structural Engineering, he completed his masters in Civil Engineering and Engineer Degree at MIT.
Users Reviews :
1. I have examined the book and find it to be an excellent book for learning the practical aspects of geotechnical engineering. The author is uptodate and thorough, yet he explains in a very down-to-earth style, by photographs and numerical examples, some very real engineering problems a geotechnical engineer is likely to face in practice.
2. I took this book in with me for the PE exam and it helped me get about 10 problems right. There are tons of examples and problems with solutions in this book. I regret not taking the geotechnical section of the PE exam.
3. Reasonably well rounded book (at a reasonably good price!) illustrating the practical aspects of geotechnical engineering. Concepts are explained in good detail and solved problems are helpful in promoting understanding. Essentially, a good book to start out your tech library, but too general in nature to be considered for a "reference text". For that, you might rely on books by Terzaghi, Peck, Thornburn, Bowles, Fang, etc.
Note : It's a Google ripped copy. Many pages are missing. I'll try to get the complete copy, either scanner or a printable version.

Fundamental Considerations For The Finite Element Analysis Of Shell Structures
Author: D. Chapellet and K. J. Bathe | Size: 1.75 MB | Format:PDF | Quality:Original preprint | Publisher: Computers & Structures, Elsevier Science Ltd. | Year: 1997 | pages: 18
Abstract :-
The objective in this paper is to present fundamental considerations regarding the finite element analysis of shell structures. First, we review some well-known results regarding the asymptotic behaviour of a shell mathematical model. When the thickness becomes small, the shell behaviour falls into one of two dramatically different categories; namely, the membrane-dominated and bending-dominated cases. The shell geometry and boundary conditions decide into which category the shell structure falls, and a seemingly small change in these conditions can result into a change of category and hence into a drama.tically different shell behaviour.
An effective finite element scheme should be applicable to both categories of shell behaviour and the rate of convergence in either case should be optimal and independent of the shell thickness. Such a finite element scheme is difficult to achieve but it is important that existing procedures be analysed and measured with due regard to these considerations. To this end, we present theoretical considerations and we propose appropriate shell analysis test cases for numerical evaluations.

Introduction :
Clays and clay minerals are very important industrial minerals. There are well over one hundred documented industrial applications of clay materials. Clays are utilized in the process industries, in agricultural applications, in engineering and construction applications, in environmental remediations, in geology, and in many other miscellaneous applications. This book is an assimilation of the major and minor uses of clays and clay minerals and explains why an understanding of the structure and physical and chemical attributes of the individual clay minerals are so important. Clay is an abundant raw material which has an amazing variety of uses and properties that are largely dependent on their mineral structure and composition. Other than the clay structure and composition, there are several additional factors which are important in determining the properties and applications of a clay. These are the non-clay mineral composition, the presence of organic material, the type and amount of exchangeable ions and soluble salts, and the texture (Grim, 1950).

Dear CivilEAns,
May a concerned CivilEAn, upload the above mentioned UK NA for wind actions for the forum's consumption.
Thanks go out to all those who have endeavoured to help out.
This book introduces the basic ideas for building discontinuous Galerkin methods and, at the same time, incorporates several recent mathematical developments. It is to a large extent self-contained and is intended for graduate students and researchers in numerical analysis. The material covers a wide range of model problems, both steady and unsteady, elaborating from advection-reaction and diffusion problems up to the Navier-Stokes equations and Friedrichs' systems. Both finite-element and finite-volume viewpoints are utilized to convey the main ideas underlying the design of the approximation. The analysis is presented in a rigorous mathematical setting where discrete counterparts of the key properties of the continuous problem are identified. The framework encompasses fairly general meshes regarding element shapes and hanging nodes. Salient implementation issues are also addressed.
