Book Review: Recent Advances in Bridge Engineering (1)
Aftab Mufti, Badiar Bakht, Leslie Jaeger
This text book is perhaps unusual in that I found it enjoyable to read. It is unusual in other respects, too, as will be described. The authors' intended readership is "their fellow engineers, especially in Asian countries" and it is also intended to be of assistance in teaching post-graduate studies.
In fact, the contents of the book provide advances in bridge engineering that likely do not appear in coherent book form elsewhere, and at least some of the topics should be useful to many bridge engineers. The authors write with authority, as they have direct personal experience with all of the subjects covered, either as researchers or as practicing engineers. The book is well written about important subject matter for bridge engineers.
The book does not attempt to cover all aspects of bridge engineering. Instead it covers, as the title suggests, recent advances in certain important areas typically not found in other publications, advances that were very much driven by Canadian engineers.
One major subject is the design of steel-free decks. It is now known that conventional concrete decks with steel reinforcing often sustain damage caused by corrosion of the steel bars. Deck replacement is expensive, even discounting the very real societal cost caused by traffic delays during renovation. However, the situation is worsening because unlike earlier bridges, the concrete deck is often an integral part of the bridge, such as the top flange of a main load-carrying member, as in a post-tensioned concrete box girder. The possibility of using non-corroding fibre-reinforced polymers instead of steel is an attractive alternative, so far not well understood by the profession. The subject is well covered in Chapter 8.
The first chapter explains how bridge design codes are written, with particular reference to determining design live loads and load factors. While few engineers are routinely engaged in this activity (except for the target part of the readership that is developing bridge design codes in Asia), it is often useful to understand why the code is written the way it is so that when situations occur that are not directly covered by the bridge design codes, some guidance is available.
Chapter 2 is on Analysis by Manual Calculation. But surely all analysis these days is performed by computer? Perhaps, but a reality check by manual methods can often provide a very useful review.
Chapter 3 covers Analysis by Computer. The ideas are good, but I suspect that any writing on this subject will be the first to experience obsolescence.
The fourth chapter is a comprehensive treatment of Arching Action in Deck Slabs. The discovery that the ubiquitous concrete bridge deck actually resists loads by arching action rather than by bending, and the ramifications of this behaviour in terms of both potential economy and the need to revise design methods, are major developments in bridge engineering pioneered by Canadian engineers, including the authors. All bridge engineers should understand this topic.
Cantilever Slabs, which do not act by arching, are covered in Chapter 5.
Chapter 6 provides good ideas and practical information from the authors' experience. Although few wood bridges are constructed these days, there are still a number in service or in remote areas that can usefully have their lives extended.
For relatively short spans, soil-steel structures can be much more economical than conventional beam-and-column bridges, and Chapter 7 is a useful guide to the design and construction of such structures.
Chapter 9 on Structural Health Monitoring is not an esoteric dissertation on instrumentation, but a pragmatic review of what can be gained from some generally fairly simple sets of load tests and measurements, and why such testing is of value.
Chapter 10 provides some thought-provoking ideas on Bridge Aesthetics. There are no recipes, but there is an invitation to raise consciousness of beauty and the contribution of a bridge to the aesthetics of its environment.
Finally, Chapter 11 gives an introduction to Computer Graphics.
All-in-all, it is a book that should be in any bridge engineers' library.

An Introduction to Seismological Research: History and Development
An Introduction to Seismological Research: History and Development
By Benjamin F. Howell Jr
Publisher: University
Number Of Pages: 201
Publication Date: 1990-10-26
ISBN-10 / ASIN: 0521385717
ISBN-13 / EAN: 9780521385718
Product Description:
Modern seismology is a relatively new science; most current ideas originated no earlier than the latter half of the nineteenth century. The focus of this book is on seismological concepts, how they originated and how they form our modern understanding of the science. A history of seismology falls naturally into four periods: a largely mythological period previous to the 1755 Lisbon earthquake; a period of direct observation from then to the development of seismometers in the late 19th century; a period during which study of seismic arrival times were used to outline the structure of the earth's interior extending the 1960s; the modern era in which all aspects of seismic waves are used in combination with trial models and computers to elucidate details of the earthquake process. This history attempts to show how modern ideas grew from simple beginnings. Ideas are rarely new, and their first presentations are often neglected until someone is able to present the evidence for their correctness convincingly. Much care has been used to give the earliest sources of ideas and to reference the basic papers on all aspects of earthquake seismology to help investigators find such references in tracing the roots of their own work.

I am writing through this forum because the original thread has been closed and this is the forum that we could raise any issue and I think, not run afoul of the rules. I read with dismay the muddle that was made of the BennyK case. This is one of the indications of the awful things that are happening in this association. When a member of a clique felt that he or whomever he feels sympathy for is piqued, that clique goes on the rampage/offensive and call for the head of the so perceived enemy to be hung on the APPIA way. This forum should not be the exclusive personal property of any one or group of people. People are here today and others are inching to come in because there are mixes of people here. There are people who also work, despite their hard schedule to keep the forum alive. So we are supposed to be humans and remember that if we are but to look on while any of us succeeds in pushing most people out of this forum, I do not think that people will have anything to lose leaving it or missing it. How can we explain a situation whereby a moderator bans a member of the association while the other members of the admin are not aware of it? And one of the reasons for banning that person was that he used a name that was similar to the self acclaimed Re, emperor pharos of Egypt. Yet he was able to come up and say that he even took pre-emptive and premeditated action before the actual banning of the person from the forum. Incredible. This is the only civilized place that I am seeing such a thing happening. And the person that was beaten was also told that he should not cry. I think that BennyP is becoming an enigma. I, as a person, will not like to belong to an association that a person in this century, despite our levels in the society herd us around and runs the place as a fiefdom. Whatever that guy (is he called BennyK) did, he deserves being given the benefit of due process. I do not think that threatening people with ban etc is the best approach to making people toe the line or dance to a perceived tone. Like I had always said and like many people will not be in agreement with me (as they will rise to defend him and call for heads to be served on hot bowls of pepper soup), we have to drive softly. It is people that make up this association. Do not drive away all the people in this association that do not appeal to you.
Regards
Teddy

1.About this book
From the reviews of the second edition:
The unique and practical Materials Handbook (second edition) provides quick and easy access to data on the physical and chemical properties of all classes of materials. The second edition has been much expanded to include whole new families of materials while many of the existing families are broadened and refined with new material and up-to-date information. Particular emphasis is placed on the properties of common industrial materials in each class. After a chapter introducing some general properties of materials, materials are classified as follows:
• ferrous metals and their alloys;
• nonferrous metals;
• semiconductors and superconductors;
• magnetic materials;
• insulators and dielectrics;
• miscellaneous electrical materials;
• ceramics, refractories and glasses;
• polymers and elastomers;
• minerals, ores and gemstones;
• rocks and meteorites;
• soils and fertilizers;
• cements, concrete, building stones and construction materials;
• timbers and woods;
• fuels, propellants and explosives;
• composite materials;
• gases;
• liquids.
Detailed appendices provide additional information on subjects as diverse as crystallography, natural radioactivity and economic data for industrial materials. Specific further reading sections and a general bibliography round out this comprehensive guide. The index and tabular format of the book make light work of extracting what the reader needs to know from the wealth of factual information within these covers.
François Cardarelli has spent many years compiling and editing materials data. His professional expertise and experience combine to make this handbook an indispensable reference tool for scientists and engineers working in fields from mechanical, electrical, and chemical to metallurgical and nuclear engineering.
"This volume covers metals and alloys, nonferrous metals, semiconductors, ceramics, polymers, earth materials, concrete, wood, fuels, composites, gases, and liquids. … many industrial and university libraries will find it a useful one-volume reference. Summing Up: Recommended. Upper-level undergraduates through professionals/practitioners." (A. M. Strauss, Choice, Vol. 46 (2), October, 2008)

1.About this book
Mankind has a fascination with measurement. Down the centuries we have produced a plethora of incompatible and duplicatory systems for measuring everything from the width of an Egyptian pyramid to the concentration of radioactivity near a nuclear reactor and the value of the fine structure constant. With the introduction first of the metric system and of its successor the Système International d'Unités (SI), the scientific community has established a standard method of measurement based on only seven core units.
The Encyclopaedia of Scientific Units, Weights and Measures converts the huge variety of units from all over the world in every period of recorded history into units of the SI. Featuring:
- An A - Z of conversion tables for over 10,000 units of measurements.
- Tables of the fundamental constants of nature with their units.
- Listings of professional societies, and national standardization bodies for easy reference.
- An extensive bibliography detailing further reading on the multifarious aspects of measurement and its units.
This huge work is simply a "must have" for any reference library frequented by scientists of any discipline or by those with historical interests in units of measurement such as archaeologists.
