PDF 4 MB
This book is the long-awaited successor to Owen Phillips's classic textbook, Flow and Reactions in Permeable Rocks, published in 1991. In the intervening 18 years between the two, significant advances have been made to our understanding of subterranean flow, especially through the vast amount of research into underground storage of nuclear waste and aquifer pollution. This new book integrates and extends these modern ideas and techniques and applies them to the physics and chemistry of sub-surface flows in water-saturated, sandy and rocky media. It describes essential scientific concepts and tools for hydrologists and public health ecologists concerned with present day flow and transport, and also for geologists who interpret present day patterns of mineralization in terms of fluid flow in the distant past. The book is ideal for graduate students and professionals in hydrology, water resources, and aqueous geochemistry.

SOIL-STRUCTURE INTERACTION - the real behaviour of structures.
info:
Prior to 1970, design practice tended to consider the ground and the structure in relative isolation. The Institution of Structural Engineers, in support of the need for recognition to be given to interactive effects, formed a special study group in 1971 to study the matter and make recommendations. This led to the setting up of an ad hoc committee which prepared the state of the art report –Structure-Soil Interaction - published in 1978.
In accordance with institution procedures the relevance of the 1978 document to current practice was reviewed and the need for revision and extension was identified. The Institution with the cooperation of the Institution of Civil Engineers and the International Association for Bridge and Structural Engineering, has responded to the current demand for adequate definition of the problems presented by the interactive effects and has initiated the preparation of this comprehensive guidance covering most types of structure.

This handbook was published in March 2006 by the Federation of Piling Specialists (FPS) to provide guidance on the principles and practical issues that relate to load testing of bearing piles, and thereby to assist informed decisions about testing requirements on construction projects involving piled foundations.
The FPS anticipates that this handbook will be of particular interest to civil or structural engineers with little or no experience of piling who find themselves in the position of specifying load testing requirements on a project involving piled foundations. The target audience for this publication also includes main contractors, management contractors and young piling engineers. Pile load testing provides an opportunity for continuous improvement in foundation design and construction practices, while at the same time fulfilling its traditional role of design validation and routine quality control of the piling works. In order to achieve this improvement, data from pile tests has to be collected and analysed to enable the piling industry, both individually and collectively, to make the best use of resources. To justify its cost to the industry, pile testing must have a value. The magnitude of this value will be increased through a better understanding of the process and its benefits.
In this handbook the Federation of Piling Specialists aims to provide guidance on issues that should be considered to enable better planning, specification and execution of pile tests, thereby increasing the value of the testing process

200 Questions and Answers on Practical Civil Engineering Works
info:
This book is intended primarily to arouse the interests of graduate engineers, assistant
engineers and engineers in the technical aspect of civil engineering works. The content of
the book mainly focuses on providing the reasons of adoption of the various current
practices of civil engineering. By understanding the underlying principles of engineering
practices, graduate engineers/assistant engineers/engineers may develop an interest in civil
engineering works. It is also intended that the book will serve as a useful source of
reference for practicing engineers.
Some of these questions are selected from the book and published in the column “The Civil
FAQ” in the monthly journal The Hong Kong Engineer under the Hong Kong Institution of
Engineer. Other than this book, I have written another book called “Civil Engineering
Practical Notes A-Z” which contains similar format and targets to provide quick and
concise answers to frequently asked questions raised by engineers during their day-to-day
work.

A DESIGN GUIDE FOR FOOTFALL INDUCED VIBRATION OF STRUCTURES
info:
Whilst footfall induced vibrations on buildings or bridges is not normally significant in terms of structural integrity, footfall vibration can be a critical serviceability condition.
This publication presents a new method for evaluating the vibration due to a single pedestrian walking on a flat surface, such as a floor slab or bridge deck. The method was developed by Arup, and has been calibrated and refined with verification measurements taken on completed structures over a period of ten years.
This guide describes a reliable methodology for predicting the vertical vibration induced
by pedestrians crossing structures such as floors and bridges.
Many methods already exist but each of these is significantly limited in some respect.
A full discussion of these limitations can be found elsewhere.
The method presented here addresses all of the issues described below in a consistent
manner:
It is applicable to any type of structure on which people walk, including floors and bridges.
It is applicable to structures of any form or construction material, e.g. steel, composite,
reinforced or pre-stressed concrete or timber structures, and enables reliable
comparisons to be made between designs of different forms and materials.
Complex irregular structures can be assessed as reliably as simple regular ones.
The footfall forcing functions recommended are based on a very extensive set of
measured data, and these loads and the likelihood of their occurrence have been
statistically quantified.
The methodology has been extensively validated and independently peer reviewed.
The method has been used routinely and regularly on design projects around the world
for the past five years, and its accuracy is validated by many measurements of
completed structures.
It interfaces well with modern engineering design methods and software packages.
The method described in this guide is based on the well-established principles of modal
analysis. This enables first principles calculations to be made, and unlike most other methods,
it does not require the introduction of arbitrary or empirical factors. This makes it a robust
approach for the assessment of any type of structure of any construction material.
The method is appropriate for calculating the vibration caused by a single pedestrian
walking on a flat surface on any structure which is significantly heavier (by at least a factor
of 10) than the individual. Whilst very simple regular structures can be assessed entirely by
hand or spreadsheet calculation, it is envisaged that the method will be used principally
in conjunction with finite element analysis as a means of estimating the modal properties
of floor and bridge structures. Whilst this might be seen as an added complexity, in practice
the additional accuracy that finite element analysis of less regular structures brings to the
assessment more than outweighs the modest additional effort associated with building
and analysing a model.
The method was developed within Arup and refined by reference to the measured performance
of completed structures over a period of ten years. It has been independently reviewed by Professor T A Wyatt of Imperial College London.

HOW TO DESIGN CONCRETE BUILDINGS TO SATISFY DISPROPORTIONATE COLLAPSE REQUIREMENTS
info:
The collapse of Ronan Point in 1968 was a seminal
event and resulted in fundamental changes to the
design philosophy of building structures in the UK.
The disaster highlighted the need for specific
consideration of the stability of structures that have
been damaged by accidents such as a gas explosion.
It was considered that, while localised damage was
unavoidable, complete collapse of structures had to
be prevented. Thus, the concept of disproportionate
collapse was born and structures had to be designed
in such a way that they would not be damaged to
an extent disproportionate to the initial effect of
the accident.
Thus in 1976 the Building Regulations1 were
amended. Buildings of five storeys or more had
to satisfy special additional requirements, which
were aimed at providing increased robustness.
More recently (2004) the Building Regulations
for England and Wales2 were amended again
to bring all buildings within the scope of the
disproportionate collapse requirements.
Approved Document A3 (AD A) is published by the
department for Communities and Local Government
(CLG) and provides more detailed guidance on
the interpretation of the Building Regulations.
This guide sets out the requirements of the AD A as
they relate to buildings constructed with concrete,
and includes some practical details to show how
to comply with the requirements. Where there is
existing, easily accessible guidance this has been
referenced rather than being repeated here.
In principle the requirements for Scotland are similar;
however, there are some variations and these
differences are also explained within this guide

Design and Construction using insulating Concrete Formwork
Alan Tovey, Prof. John Roberts, Michael Kilcommons
ISBN 1-904482-31-7
The Concrete Centre
2007
104p
info:
Insulating concrete formwork (ICF) is an innovative modern method of construction, which
combines the inherent strength of concrete with the excellent thermal insulation properties
of polystyrene to produce cost-effective and durable structures. The polystyrene is used
as permanent formwork for the concrete and is available as either expanded or extruded
polystyrene, in a variety of configurations and a number of proprietary systems. The basic
structure is typically erected by a team of three or four site operatives and fi lled by pumping
a very workable concrete in storey-height lifts. In addition to providing a strong structure,
the concrete provides excellent sound insulation, fi re resistance and the ability for thermal
capacity. Designers appreciate the basic elegance and simplicity of ICF systems and have
been quick to employ them for a variety of applications. The purpose of this guide is to
provide designers and contractors with a thorough understanding of Insulating Concrete
Formwork.

How to Design Concrete Structures using Eurocode 2
info:
The introduction of European standards to UK construction is a signifi cant event. The ten design standards, known
as the Eurocodes, will affect all design and construction activities as current British Standards for design are due
to be withdrawn in 2010 at the latest. BS 8110, however, has an earlier withdrawal date of March 2008. The aim
of this publication is to make the transition to Eurocode 2: Design of concrete structures as easy as possible by
drawing together in one place key information and commentary required for the design and detailing of typical
concrete elements.
The cement and concrete industry recognised that a substantial effort was required to ensure that the UK design
profession would be able to use Eurocode 2 quickly, effectively, effi ciently and with confi dence. With support
from government, consultants and relevant industry bodies, the Concrete Industry Eurocode 2 Group (CIEG)
was formed in 1999 and this Group has provided the guidance for a co-ordinated and collaborative approach to
the introduction of Eurocode 2. Part of the output of the CIEG project was the technical content for 7 of the 11
chapters in this publication. The remaining chapters have been developed by The Concrete Centre.
