When bridges fail, often with loss of human life, those involved may be unwilling to speak openly about the cause. Yet it is possible to learn from mistakes. The lessons gained lead to greater safety and are a source of innovation. This book contains a systematic, unprecedented overview of more than 400 bridge failures assigned to the time of their occurrence in the bridges' life cycle and to the releasing events. Primary causes are identified. Many of the cases investigated are published here for the first time and previous interpretations are shown to be incomplete or incorrect. A catalogue of rules that can help to avoid future mistakes in design analysis, planning and erection is included. A lifetime's work brilliantly compiled and courageously presented - a wealth of knowledge and experience for every structural engineer.

This book provides a detailed review and summary of twenty-two case studies of fracture and fatigue in bridge structures. Its two parts cover cracks formed as a result of low fatigue resistant details, and cracks resulting from unanticipated secondary or displacement induced stresses.

When States Fail

Since 1990, more than 10 million people have been killed in the civil wars of failed states, and hundreds of millions more have been deprived of fundamental rights. The threat of terrorism has only heightened the problem posed by failed states. When States Fail is the first book to examine how and why states decay and what, if anything, can be done to prevent them from collapsing. It defines and categorizes strong, weak, failing, and collapsed nation-states according to political, social, and economic criteria. And it offers a comprehensive recipe for their reconstruction. The book comprises fourteen essays by leading scholars and practitioners who help structure this disparate field of research, provide useful empirical descriptions, and offer policy recommendations. Robert Rotberg's substantial opening chapter sets out a theory and taxonomy of state failure. It is followed by two sets of chapters, the first on the nature and correlates of failure, the second on methods of preventing state failure and reconstructing those states that do fail. Economic jump-starting, legal refurbishing, elections, the demobilizing of ex-combatants, and civil society are among the many topics discussed. All of the essays are previously unpublished. In addition to Rotberg, the contributors include David Carment, Christopher Clapham, Nat J. Colletta, Jeffrey Herbst, Nelson Kasfir, Michael T. Klare, Markus Kostner, Terrence Lyons, Jens Meierhenrich, Daniel N. Posner, Susan Rose-Ackerman, Donald R. Snodgrass, Nicolas van de Walle, Jennifer A. Widner, and Ingo Wiederhofer.

Understanding Bridge Collapses

In a straightforward style, this book presents a detailed overview of 20 cases of famous and other highly interesting bridge collapses over the last two centuries. Every case is illustrated and described in detail and the failure analyses made are supported by well-known explanations and, in some cases, by new theories. The chronological order makes it easy to follow the gradual development in the use of different bridge types and the choice of construction material. The increase of knowledge and experience in the structural engineering discipline over the years is clearly observable, although every modern engineer will admit that both fatigue and buckling are very complex phenomena and that knowledge about them can increasingly profit from studying past bridge construction projects failures. Intended for consulting engineers (bridges, steel and metal structures) and for advanced-level and postgraduate students in structural and bridge engineering.

Proven methods for preventing and mitigating bridge and highway flood scour Offering detailed guidelines on bridge scour countermeasures, this comprehensive resource provides a proactive strategy for the design and construction of bridges to prevent scour, as well as a reactive plan for post-flood disaster management. Topics discussed include erosion, causes of scour, AASHTO design codes, hydrology, hydraulics, scour analysis, inspection methods, and modern materials technology. Real-world case studies illustrate the concepts presented. The authoritative information in this practical guide will help you to develop more efficient and cost-effective design processes and bridge management systems for river bridges subjected to floods. Flood Scour for Bridges and Highways covers: Floods, scour problems, and mitigation River instability caused by flow obstructions Past failures and bridges vulnerable to failure Geotechnical and hydraulic issues at scour-critical rivers and bridges Hydrology, floods, and scour-critical bridges Estimating scour depths and selecting applicable countermeasures Inspections, ratings, and monitoring countermeasures FHWA, HEC-18, and HEC-23 scour countermeasures as remediation Innovative methods of flood control and disaster management
