Dams and Appurtenant Hydraulic Structures

Water, one of the few natural resources without which there is no life, is distributed
throughout the world unevenly in terms of place, season and quality. For this reason it
is essential to construct dams on rivers, thus forming reservoirs for the storage and the
even use of water. To date, forty-two thousand large dams have been built worldwide,
and hundreds of thousands of smaller ones, which have made possible a rational use
of a certain amount of river water – the most important water resource for human
life and activity. Dams, together with their appurtenant hydraulic structures, belong
among the most complex engineering works, above all because of their interaction with
the water, their great influence on the environment and their high cost. Therefore great
significance is given to theoretical research relating to dams, to improving the methods
of analysing and constructing them, and to the knowledge gained in the course of their
exploitation. In the past forty years great progress has been made in this respect.

Water plays an exceptionally significant role in the economy and in the life of all coun-
tries. It is of crucial importance to the existence of people, animals, and vegetation. The
settling of people in different regions of the Earth has always been closely dependant
on the possibilities for water supply, parallel with those for providing food, shelter,
and heat. The increase in population, as well as the development and enrichment of
mankind, in a number of places has reached a level at which the water supply, needed
for the population, industry, irrigation, and production of electric power, has been

brought to a critical point.

On the other hand, reserves of water on Earth are very large. They have been
estimated to amount to 1.45 billion km3 (Grishin et al., 1979). If we assume that
the above quantity of water is uniformly spread over the Earth’s surface, then the
thickness of such a water layer would be almost 3,000 m. As much as 90% of that
quantity is attributable to the water of oceans and seas, while the remainder of barely
10% belongs to lakes, rivers, underground waters, and glaciers, as well as moisture
from water in the atmosphere. Only 1/5 of the freshwater, which is suitable for man’s
life and activities, is available for use.

Concrete Construction Engineering Handbook

Portland cement concrete is a composite material made by combining cement, supplementary cementing materials, aggregates, water, and chemical admixtures in suitable proportions and allowing the resulting mixture to set and harden over time.

Because hardened concrete is a relatively brittle material with a low tensile strength,

strength, steel reinforcing bars and sometimes discontinuous fibers are used in structural concrete to provide some tensile load-bearing capacity and to increase the toughness of the material.

In this chapter, we deal with some of the basic constituents: cements, aggregates, water, steel reinforcement, and fiber reinforcement.

Chemical admixtures and supplementary cementing materials (often referred to as mineral admixtures) are covered in Chapter 2.

It must be emphasized that choosing the appropriate

200 Questions and Answers on Practical Civil Engineering Works

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.

BOUNDARY ELEMENTS Theory and Applications

The last three decades have been marked by the evolution of electronic computers
and an enormous and wide-spread availability of computational power. This has

boosted the development of computational methods and their application in engi-
neering and in the analysis and design of structures, which extend from bridges to

aircrafts and from machine elements to tunnels and the human body. New scientific

subfields were generated in all engineering disciplines being described as “Compu-
tational”, e.g. Computational Mechanics, Computational Fluid Mechanics, Com-
putational Structural Analysis, Computational Structural Dynamics etc. The Finite

Element Method (FEM) and the Boundary Element Method (BEM) are the most
popular of the computational methods. While the FEM has been long established
and is most well known in the engineering community, the BEM appeared later
offering new computational capabilities with its effectiveness, accuracy and low
computational cost.

Although the BEM is taught as a regular course at an ever increasing number of
universities, there is a noticeable lack of a textbook which could help students as
well as professional engineers to understand the method, the underlying theory and
its application to engineering problems. An essential reason is that BEM courses

are taught mainly as advanced graduate courses, and therefore much of the under-
lying fundamental knowledge of mathematics and mechanics is not covered in the

respective undergraduate courses. Thus, the existing books on BEM are addressed
rather to academia and researchers who, somehow, have already been exposed to
the BEM than to students following a BEM course for the first time and engineers
who are using boundary element software in industry.

BIM Handbook A Guide to Building Information Modeling

The BIM Handbook is addressed to building developers, owners, managers, and inspectors; to architects, engineers of all disciplines, construction contractors, and fabricators; and to students of architecture, civil engineering, and building construction. It reviews Building Information Modeling and its related technologies, its potential benefi ts, its costs and needed infrastructure.

It also discusses the present and future infl uences of BIM on regulatory agencies; legal practice associated with the building industry; and manufacturers of building products it is directed at readers in these areas. A rich set of BIM case studies are presented and various BIM tools and technologies are described. Current and future industry and societal impacts are also explored.

BIM is developing rapidly, and it is diffi cult to keep up with the advances in both technology and practice.

Integrated Project Delivery (IPD) is a collaborative contracting paradigm that has been developed and adopted within the three years since we completed the fi rst edition. BIM tools are increasingly used to support sustainable design, construction, and operation.

There has been increasing support by BIM for lean design and construction methods which are highlighted throughout the book. Some innovations we predicted would become commercial by 2012, such as tracking of building components using BIM and radio-frequency ID tagging, have already been used in practice.

This edition not only addresses these themes and updates the material relate to the BIM applications; it also introduces sections on new technologies, such as laser scanning and BIM servers. It also includes six new case studies.

AutoCAD Secrets Every User Should Know

CAD software is used in so many fields of design that it would be impossible to develop
extensive standards that apply to all of them.

I’ve trained people who use AutoCAD to design quilts, hearing aids, doll clothes, houses, barns, commercial buildings, M16s, submarine hatches, and the myriad components of machinery. But there are some foundational rules that represent a consensus among serious users of CAD.

You’ll find exceptions to these rules, of course, but think of them the way you think of the rules for dimensioning drawings: You follow them if possible. The fact that a rule has rare exceptions doesn’t reduce its value as a guide.

You certainly follow the rules requiring you to drive on the proper side of the road all the time except when a dog darts out in front of you, or the road is washed away by a flash flood, or you’re passing someone. So, here are some of my rules for using AutoCAD.

Much of the material in this book was developed for the Advanced AutoCAD course at Southern Maine Community College and then used in presentations at Autodesk University
over the past decade. The topics derive from the kinds of questions I’ve been asked over the years by people who use AutoCAD every day.

This isn’t meant to be a comprehensive book about AutoCAD. I’ve tried to identify common problem areas and provide some advice on how to approach them.

I’m also trying to preserve some traditional knowledge that is often overlooked by users: knowledge as simple as making proper centerlines, as arcane as using DOS to improve efficiency, as exciting as programming, and as dramatic as 3D modeling. Here’s a brief review of what’s covered in each chapter.
