The Foundation Engineering Handbook (Gunaratne)

This handbook contains some of the most recent developments in theoretical and applied
foundation engineering in addition to classical foundation design methods. The inclusion of
recent developments mostly enriches the classical design concepts in Chapters 3–7, 10 and 11.

It also enables the reader to update his or her knowledge of new modeling concepts applicable
to foundation design. Most recently developed in situ testing methods discussed in detail in
Chapter 2 certainly familiarize the reader with state-of-the-art techniques adopted in site
testing.

In addition, modern ground stabilization techniques introduced in Chapter 12 by an
experienced senior engineer in Hayward-Baker Inc., a leading authority in site improvement
work across North America, provides the reader with the knowledge of effective site
improvement techniques that are essential for foundation design.

Innovative and widely used methods of testing pile foundations are introduced with numerical illustrations in Chapters 2 and 7. LRFD designs in Chapters 3 and 6 and the design of retaining structures with geogrids included in Chapter 10 are unique features of this foundation engineering handbook.

For the benefit of the reader, the basic and advanced soil mechanics concepts needed in foundation design are elaborated with several numerical examples in Chapter 1.

Calcul des structures métalliques selon l’Eurocode 3

Avant 1993, la conception et le calcul des constructions métalliques étaient régis par diverses réglementations. Aujourd’hui, une nouvelle norme européenne est entrée en vigueur et impose, en remplacement des précédents textes, un texte unique : l’Eurocode 3.

Cet ouvrage se présente comme :

un traité théorique qui regroupe les calculs fondamentaux des structures en acier, à partir des données fondamentales de la résistance des matériaux et de la mécanique des solides
un traité pratique qui comporte systématiquement des applications et des exemples de calculs détaillés de pièces ou d’ouvrages établis sur la base du nouveau règlement européen Eurocode 3
un support pédagogique pour l’enseignement, les écoles d’ingénieurs, IUT, BTS, les écoles d’architecture
un outil de travail et de réflexion pour les professionnels de la construction
un guide pratique qui souligne les points et les dispositions exigeant une attention toute particulière qui met en garde contre les risques et les désordres encourus, notamment en ce qui concerne les assemblages et les phénomènes d’instabilité (flambement, déversement, voilement) qui demeurent des pôles névralgiques de toutes constructions métalliques

Reinforced Concrete Design Theory and Examples

The third edition of the book has been written to conform to BS 8110 1997 the code for
structural use of concrete and BS 8007:1987 the code for Design of structures for retaining
aqueous liquids. The aim remains as stated in the first edition: to set out design theory
and illustrate the practical applications of code rules by the inclusion of as many useful
examples as possible. The book is written primarily for students on civil engineering
degree courses to assist them to understand the principles of element design and the procedures for the design of concrete buildings. The book will also be of assistance to new
graduates starting on their career in structural design.

The book has been thoroughly revised to conform to the updated code rules. Many new examples and sections have been added. In particular the chapter on Slabs has been considerably expanded with extensive coverage of Yield line analysis, Hillerborg’s strip
method and design for predetermined stress fields. In addition, four new chapters have
been added to reflect the contents of university courses in design in structural concrete.
The new chapters are concerned with design of prestressed concrete structures, design of
water tanks, a short chapter comparing the important clauses of Eurocode 2 and finally a
chapter on the fundamental theoretical aspects of design of statically indeterminate structures,
an area that is very poorly treated in most text books.

Design and Construction of Tunnels: Analysis of Controlled Deformations in Rocks and Soils

Geological hazard and the lack of appropriate survey, design and construction instruments for tackling those terrains we call “difficult”, with good prospects of success, have always made the design and construction of underground works a risky affair, which could not therefore be faced with the same degree of accuracy as other civil engineering works. As a consequence they have always occupied a subordinate position with respect to similar surface constructions and in the past they were only resorted to when the latter seemed impractical or of little use.

The purpose of this book is not just to illustrate the basic concepts of the approach as fully and exhaustively as possible and to show how, by following its principles, underground works can be designed and constructed with a reliability and accuracy never attained before. Its purpose is above all to furnish the scientific community with a useful reference text around which all may work together to improve the ADECO-RS approach or even to go beyond it.

Dictionary of Construction Terms

This Dictionary of Construction Terms is intended to cover a wide range of the more common as well more esoteric yet important terms a building professional,

lawyer, student, judge, arbitrator, adjudicator, engineering economist or the like may require defi nition upon in the construction law fi eld.

The intention is to clear the fog, and to do so concisely in clear English in an alphabetical format.

So whether you are looking for the answer to a spandrel panel, chequerplate, revetment,

or NAECI or what is meant by nemo dat quod non habet or the rule in Pinnel’s case, we have it here, and a whole lot more.

In about 1994 I started assembling a construction database on my Psion Organiser

(for those that can remember such pocket computers) regularly adding building and engineering terms,

legal references etc relevant to the fi rm’s work as construction lawyers.

I was always excited to learn new terms and add to the record. Then about 10 years ago with the advent of powerful networked computing and software systems,

Fenwick Elliott created its own intranet platform, and that database was uploaded toit.

It was coined by the offi ce, “Simon Says”.

This data rapidly grew with our busy international practice and with projects

that are more complex the legal issues thrown up blossomed in tandem with the new technologies.

Formwork a Practical Guide

Amongst the many trades on a typical building site, the role and responsibilities of the formworker are unique.

There are few restrictions placed on his choice of working techniques.

In contrast, other trades are constrained by the most precise directions.

For the structural steelwork all sizes, connections, fixings and painting are defined in detail.

Reinforcement grades, sizes, positions, laps and tolerances are all predetermined.

Joinery is exhaustively detailed, colour schemes are prescribed, and furnishings selected.

Compared to this, the formworker is almost permitted to be a free spirit.

Most times, the only constraints are mandatory requirements on the concrete surface quality and accuracy, together with the builder’s demands on cost and time.

Outside this, he chooses his own formwork system, selects his materials and components, and devises the general arrangement and the details of construction.

Three general principles govern formwork design and construction:

QUALITY
SAFETY
ECONOMY.

These three matters are not separate and unrelated. Experienced formworkers know that it is a false economy to reduce quality.

Further, if the formworker feels safe, this will lead to more production and thus reduced costs.

Throughout this book, even if they are not specifically mentioned, these three principles are fundamental to all the matters described.

In this chapter their further discussion will relate ‘Quality’ to the quality of the concrete structure being produced, ‘Safety’ to both personal safety and formwork loading,

and ‘Economy’ to the matters that affect the total effective cost of formwork and the contribution of this to the total cost of the concrete structure.

The activity of formwork construction, its concreting and subsequent stripping, can
also have a significant loading effect on the permanent concrete structure being built.

The design engineer for the permanent structure may place restrictions on the formworkers activities.

The formworker must ensure that full INFORMATION has been supplied on these and any other requirements that will influence the materials, methods of use and quality of the formwork.

FRP Composites for Reinforced and Prestressed Concrete Structures

Fiber-reinforced polymer (FRP) is a common term used by the civil engineering community for high-strength composites.

Composites have been used by the space and aerospace communities for over six decades and the use of composites by the civil engineering community spans about three decades.

In the composite system, the strength and the stiffness are primarily derived from fibers, and the matrix binds the fibers together to form structural and nonstructural components.

Composites are known for their
high specific strength, high stiffness, and corrosion resistance.

Repair and retrofit are still the predominant areas where FRPs are used in the civil engineering community.

The field is relatively young and, therefore, there is considerable ongoing research in this area.
American Concrete Institute Technical Committee 440 documents are excellent sources
for the latest information.

The primary purpose of this book is to introduce the reader to the basic concepts of repairing and retrofitting reinforced and prestressed concrete structural elements using FRP.

Basic material properties, fabrication techniques, design concepts for strengthening in bending, shear, and confinement, and field evaluation techniques are presented.

The book is geared toward advanced undergraduate and graduate students, professional engineers, field engineers, and user agencies such as various departments of transportation.

A number of flowcharts and design examples are provided to facilitate easy and thorough understanding.

Since this is a very active research field, some of the latest techniques such as near

-surface mounting (NSM) techniques are not covered in this book.

Rather, the aim is to provide the fundamentals and basic information.

Workability and Quality Control of Concrete

The word workability is a term that refers to properties of fresh concrete, that is, of the concrete before it has set and hardened, and it is legitimate to ask why any attention should be given to these properties at all.

The performance of concrete will in practice be assessed in terms of whether the hardened material performs in the way intended and continues to do so: it will be judged in terms of shape and finish, strength, deflection, dimensional changes, permeability and durability.

So why should the properties of the fresh concrete be considered to be important, and why should they be the concern of the practising engineer?

The answer to the first of these questions lies in the fact that the properties of any finished material are affected by the properties at an earlier stage and by the processes applied to it, while the answer to the second one is that all, or a major part of, the processing of concrete is actually carried out on site.

The first stage is, of course, the making of a homogeneous mix and then, assuming this has been done properly, the material is subjected to other processes as follows.

The concrete must be capable of giving a good finish direct from the formwork, withouth oneycombing or an excessive number of blowholes or other surface defects.

If there is a free surface, it must also be capable of giving a good finish in response to an operation such as floating or trowelling.

A workable concrete is one that satisfies these requirements without difficulty and, ingeneral, the more workable it is, that is, the higher its workability, the more easily it can be placed, compacted and finished.

Workability can be increased by simply increasing the water content of the mix but, if that method is used, a point will be reached at which segregation and/or bleeding become unacceptable so that the concrete is no longer homogeneous and, before that, the water/cement ratio may have reached a level such that the hardened concrete will not attain the required strength.
