The Design of Modern Steel Bridges

ISBN: 9780632055111 出版年：2008 页码：226 Sukhen Chatterjee Wiley

The purpose of this book is to explain the nature of the problems associated with the building of bridges with steel as the basic construction material, then to examine the theories that are available to solve these problems. The book begins with a technological history of the development of different types of iron and steel bridges. The basic properties of steel as a building material for bridges are then described. The natural and traffic-induced forces and phenomena that a bridge structure must resist are then identified and quantified with reference to practices in different countries. The next chapter explains the process of structural design, the basic functional aims and how the mathematical theories are applied. This subject is treated in the context of limit state and statistical probability concepts. Then follows detailed guidance on the design of plate and box girder bridges, the most common form of construction adopted for steel bridges in modern times. The buckling bahavior of various components, the effects of geometrical imperfections and large-deflection behavior, and the phenomenon of post-buckling reserves are described in great detail. The rationale behind the requirements of various national codes and the research that helped their evolution are explained, and some design examples are worked out to illustrate their intended use. An Index is provided.
