Highways Department (HyD) of Hong Kong SAR is turning their idea for a world class bridge across
Rambler Channel at the entrance to Kwai Chung Container Port into reality. Due to the spectacular
location, HyD selected the concept for the bridge through an international design competition. The
competition took place in the first half of 2000 and the winning concept was a cable-stayed structure
with freestanding towers located between twin box girder decks. The 1018m main span is in steel,
while the four back spans each side are in concrete. The two towers stand on shore, providing
unobstructed access to the busy container port with a minimum navigation headroom of 73.5m.
A number of modifications were introduced to the scheme during subsequent technical review.
Detailed design started in March 2002. Tender was called in August 2003 and returned in December
2003. The construction contract was awarded to the Maeda-Hitachi-Yokogawa-Hsin Chong Joint
Venture, and construction began in April 2004. At the end of 2007, the concrete back spans were
complete and the towers were well on their way to their final heights of 298m forming significant
landmarks against the backdrop of Hong Kong harbour. Major sections of the steel deck, fabricated in
China, are now on site, with the areas around each tower erected by a 4000T heavy lift strand jacking
scheme. The first of the prefabricated parallel wire stay cables have been erected. Completion of the
bridge is scheduled for 2009.

This volume contains a selection of papers presented at Fatigue Design 95 held in Helsinki, Finland from 5-8 September 1995. The papers have been peer reviewed and present practical aspects for the design of components and structures to avoid fatigue failure.
Topics covered include: fatigue design experiences, ground vehicle components, component reliability, multiaxial fatigue, notch analysis, service loading, welded structures, probabilistics aspects in fatigue, fatigue design optimization.

Steels: Processing, Structure, and Performance is a comprehensive guide to the broad, dynamic physical metallurgy of steels. The volume is an extensively revised and updated edition of the classic 1990 book Steels: Heat Treatment and Processing Principles. Eleven new chapters expand the coverage in the previous edition, and other chapters have been reorganized and updated.
This volume is an essential reference for anyone who makes, uses, studies, or designs with steel. The interrelationships between chemistry, processing, structure, and performance--the elements of physical metallurgy--are integrated for all the types of steel discussed. The evolution, characterization, and performance of steel microstructures are described, with increased emphasis on deformation and fracture.
Heat treatment remains a vital aspect of the manufacture of steel products, and the coverage of thermal processing and its effect on steels is expanded in this edition. Dramatic changes in steel manufacture have occurred in the 15 years since the publication of the 1990 edition. Low-carbon sheet steels have experienced the most dynamic changes: thermal processing of sheet steels on a massive continuous scale has produced new grades with only subtle changes in chemistry. Low carbon sheet steels, together with strengthening mechanisms, developments in microalloyed forging steels, steels with bainitic and a variety of ferritic microstructures, quench and tempered steel performance, high-carbon steels for rail and ultra-high strength wire, and the causes of low toughness and embrittlement are all discussed in new chapters.

For newly hired young engineers assigned to their first real project, there has been little to offer in the way of advice on where to begin, what to look out for and avoid, and how to get the job done right. This book is intended to give just that sort of help from an author with long experience as senior engineer in government and industry (U.S. Army Corps of Engineers and Exxon-Mobil). Beginning with guidance on understanding the typical organizational structure of any type of technical firm or company, and then going on to providing help on getting started with a project team, understanding key roles, and avoiding common pitfalls of new engineers, the author provides numerous hands-on examples of typical projects from representative industries and organizations of all kinds. In addition, the book will offer unique help on first-time experience working in other countries with engineering cultures that can be considerably different from that found in the U.S.
Reviews essentials of management for any new engineer suddenly thrust into responsibility
Emphasizes skills that can get you promotedand pitfalls that can get you fired
Expanded case study to show typical evolution of a new engineer handed responsibility for a major design project

Seismic shaking can transform water-saturated sand into a liquid mass that will not support heavy loads such as buildings. This phenomenon, called liquefaction, causes much of the destruction associated with some earthquakes. Mexico City, for example, rests on the ancient lakebed of Lake Texcoco, which is a large basin filled with liquefiable sand and ground water. In the Mexico City earthquake of 1985, the wet sand beneath tall buildings liquefied and most of the 10,000 people who died were in buildings that collapsed as their foundations sank into liquefied sand.
Jets of sand sometimes erupt from the ground during an earthquake. These sand geysers or mud volcanoes occur when formations of soft, wet sand is liquefied and forcefully squeezed up through cracks in the ground. Despite these names, they have no relation to real geysers or volcanoes. Although they generally cause little damage, they are indications that more widespread liquefaction may have occurred or may be possible in the next earthquake.
