Captures Current Developments in Bridge Design and Maintenance

Recent research in bridge design and maintenance has focused on the serviceability problems of older bridges with aging joints. The favored solution of integral construction and design has produced bridges with fewer joints and bearings that require less maintenance and deliver increased durability. Bridge Deck Analysis, Second Edition outlines this growing development, and covers the structural analysis of most common bridge forms. It introduces reliability analysis, an emergent method that allows bridge engineers to determine risk when maintaining older or damaged bridges.







Explains the Background Theory along with Practical Tools

This book includes practical examples of everyday problems in bridge engineering, and presents real-life examples of the application of reliability analysis. The authors show how reliability analysis can determine structural safety even for bridges which have failed a deterministic assessment. They also update other chapters to reflect the most current advancements towards more sophisticated analysis, and the more widespread use of finite element software.







Whats New in this Edition:











Incorporates new research on soil-structure interaction A new section with examples of how to analyze for the effects of creep Greatly expands the sections on 3-D brick finite elements Now consistent with both Eurocodes and AASHTO standards

An appropriate resource for senior undergraduates taking an advanced course on bridge engineering, Bridge Deck Analysis is also suitable for practicing engineers, and other professionals involved in the development of bridge design.

Arvustused

"This book is very useful for both teaching and designing purposes." Dr. Stergios Mitouls, University of Surrey, UK

"A book of this type risks being accused of being superficial to the expert and overly complex to the graduate. This is not the case.... A worthy successor to Hambly's Bridge Deck Behaviour."

Richard Cooke, Proceedings of the ICE: Bridge Engineering
