Failed Bridges by Joachim Scheer Pdf

Gilt immer noch, dass ein Bauwerkseinsturz der beste Lehrmeister für den Fortschritt des Bauens ist? Oder, anders formuliert: Ist Bauen dann, wenn wir das Bewährte verlassen und Neues wagen, "Experimentieren"? Über die Ursache von Schadensfällen und Einstürzen, die oft mit dem Verlust von Menschenleben verbunden sind, wird nicht gern öffentlich gesprochen. Aber aus Fehlern kann man lernen. Die Lehren und Erfahrungen aus den Schadensauswertungen führen zu mehr Sicherheit und oft zum Innovationsschub. Die Kenntnis der Schadensursachen ist Voraussetzung für ihre zukünftige Vermeidung. Mit diesem Buch liegt eine systematische Zusammenstellung von über 400 Versagensfällen vor, die in besonderer Weise betrachtet werden: Sie werden nach dem Zeitpunkt ihres Auftretens im Lebenszyklus der Brücke, z. B. im Bauzustand oder im Betrieb, und nach den Schadensereignissen, z. B. Anprall oder Erdbeben, geordnet. Die wichtigsten Ursachen sind: menschliches Versagen, mangelnde Aussteifung, Materialversagen oder Überlastung. Es werden vorwiegend Brückeneinstürze, die in der Literatur wenig oder nach dem Urteil des Verfassers nicht vollständig oder nicht zutreffend behandelt sind, ausführlich analysiert. Mit Akribie gesammelt, kompetent und exzellent aufgearbeitet und mit Mut präsentiert, ergibt dies eine unverzichtbare Erkenntnisquelle für jeden Bauingenieur in der Praxis und für das Studium. Ein Katalog von Regeln wurde erstellt. Seine Beachtung kann helfen, Fehler bei Entwurf, Planung und Ausführung zu vermeiden.

Bridges by George C. Lee,Ernest Sternberg Pdf

A multidisciplinary and accessible introduction to humanity’s favorite structure: the bridge. Whether you are a student considering a career in civil engineering and transportation planning, a public official interested in the future of infrastructure, or a person who simply cares about bridges, this book offers an accessible and illustrated introduction to the most beloved feature of our built environment. Learn about engineering basics: the forces that bridges must resist to stay aloft and the principles by which engineers decide which types of bridges make sense at which sites. Find out how engineers protect bridges from their greatest threats—the earthquakes, floods, and other hazards that can cause catastrophic damage. Moving from engineering to planning, learn how we decide whether a bridge is worth building in the first place, learn about controversial features of cost-benefit analysis, and about the transportation models by which planners forecast bridge effects on traffic patterns. Investigate a sometimes intractable problem: why a project often creeps along for a decade or more to get from initial studies to the day the ribbon is cut, undergoing vast cost escalations. Also explore the environmental impact of bridges, and the meaning of a “sustainable bridge,” and whether bridges could once again be built, like ancient Roman ones, to last a thousand years. “Authoritative, comprehensive, and fun to read, this book is for everyone interested in bridges, from the lay reader to the techie who likes to see how things work. It also will serve as an excellent companion to beginning design students in architecture and engineering, and it should be on the shelf of civil engineers, architects, and contractors, too.” — Robert E. Paaswell, City College of New York “This work will help educated but nonspecialist decision makers to appreciate the complexity of bridge design, construction, and maintenance in making decisions that impact bridges.” — Niraj Verma, Virginia Commonwealth University

Reliability and Safety of Cable-Supported Bridges by Naiwei Lu,Yang Liu,Mohammad Noori Pdf

Bridge design and construction technologies have experienced remarkable developments in recent decades, and numerous long-span bridges have been built or are under construction all over the world. Cable-supported bridges, including cable-stayed bridges and suspension bridges, are the main type of these long-span bridges, and are widely used in highways crossing gorges, rivers, and gulfs, due to their superior structural mechanical properties and beautiful appearance. However, cable-supported bridges suffer from harsh environmental effects and complex loading conditions, such as heavier traffic loads, strong winds, corrosion effects, and other natural disasters. Therefore, the lifetime safety evaluation of these long-span bridges considering the rigorous service environments is an essential task. Features: Presents a comprehensive explanation of system reliability evaluation for all aspects of cable-supported bridges. Includes a comprehensive presentation of the application of system reliability theory in bridge design, safety control, and operational management. Addresses fatigue reliability, dynamic reliability and seismic reliability assessment of bridges. Presents a complete investigation and case study in each chapter, allowing readers to understand the applicability for real-world scenarios. Reliability and Safety of Cable-Supported Bridges provides a comprehensive application and guidelines for system reliability techniques in cable-supported bridges. Serving as a practical educational resource for both undergraduate and graduate level students, practicing engineers, and researchers, it also intends to provide an intuitive appreciation for probability theory, statistical methods, and reliability analysis methods.

Knox County Bridges by Donald Edgar Boyd Pdf

Knox County had its beginnings at the confluence of the waters of Center Run with the Kokosing River. This pictorial history of the spanning of area waterways is mostly a story of disasters. Many of the photographs are of the wreckage of failed bridges and what is left of the vehicles that brought them down. They depict a county highway department that was only reactive. The practice was to send the crews out to pick up the pieces and then figure out how to repair or replace the bridge. Changes began to occur with the Silver Bridge disaster in 1967 over the Ohio River, as the federal government instituted inspection of all public bridges at two-year intervals. With the information afforded through inspections and additional funding mechanisms, counties by the mid-1980s had the tools to be proactive toward bridge maintenance. A scheduled plan to inspect structures for repairs or replacement prior to failure began to occur. During this period, construction materials other than timber--stronger and longer-lasting materials--became the norm, thus saving lives.

An Encyclopaedia of World Bridges by David McFetrich Pdf

Bridges are one of the most important artefacts constructed by man, the structures having had an incalculable effect on the development of trade and civilisation throughout the world. Their construction has led to continuing advances in civil engineering technology, leading to bigger spans and the use of new materials. Their failures, too, whether from an inadequate understanding of engineering principles or as a result of natural catastrophes or warfare, have often caused immense hardship as a result of lost lives or broken communications. In this book, a sister publication to his earlier An Encyclopaedia of British Bridges (Pen & Sword 2019), David McFetrich gives brief descriptions of some 1200 bridges from more than 170 countries around the world. They represent a wide range of different types of structure (such as beam, cantilever, stayed and suspension bridges). Although some of the pictures are of extremely well-known structures, many are not so widely recognisable and a separate section of the book includes more than seventy lists of bridges with distinctly unusual characteristics in their design, usage and history.

Arch Bridges by A. Sinopoli Pdf

Modern structural engineering surprises us with the mastery and certainty with which it plans and carries out daring projects, such as the most recent metal or concrete bridges, whether they be suspension or arch bridges. On the other hand, little is yet known about the state of knowledge of construction science and techniques which, well before the arrival of modern methods based on the mechanics of deformable continua, made it possible in the past to erect the vaulted masonry structures rthat we have inherited. The fact that these have lasted through many centuries to our time, and are still in a fairly good state of conservation, makes them competitive, as far as stability and durability are concerned, with those constructed in other materials. Although it is known that the equilibrium of the arch is guaranteed by any funicular whatsoever of the loads, contained inside the profile of an arch, finding the unique solution is not such a certainty. In other words, the problem of the equilibrium of vaulted structures is 'Poleni's problem', the one for which the Venetian scientist was able to give an exemplary solution on the occasion of the assessment of the dome of St. Peter's. Arch Bridges focuses on the main aspects of the debate about the masonry arch bridge: History of structural mechanics and construction, theoretical models, analysis for assessment, numerical methods, experimental and non-destructive testing, maintenance and repair are the topics of the Conference. The breadth and variety of the contributions presented and discussed by leading experts from many countries make this volume an authoritative source of up-to-date information.

Building Bridges: Between Theory And Practice by David Blockley Pdf

The book is about bridging the huge gaps between what engineers know, what they do and why things go wrong. It puts engineering into a wider perspective so readers can see how it relates to other disciplines — especially science and technology. Many intellectuals have dismissed engineering as 'applied science', but this book shows how wrong it is to do so — engineers apply science, but their purpose is quite different.It takes the reader on a learning journey of reflections on the gaps between theory and practice in professional life — not just in engineering but across all disciplines. The learning is summarized through 20 learning points or lessons, each one placed in context. Some of the important lessons are about learning from failure, joining-up theory and practice, understanding process, classifying uncertainty, managing risks, finding resilience, thinking systems to improve performance and nurturing practical wisdom.

America's Covered Bridges by Terry E. Miller,Ronald G. Knapp Pdf

As many as 15,000 covered bridges were built in North America over the past 200 years. Fewer than 1,000 remain. In America's Covered Bridges, authors Terry E. Miller and Ronald G. Knapp tell the fascinating story of these bridges, how they were built, the technological breakthroughs required to construct them and above all the dedication and skill of their builders. Each wooden bridge, whether still standing or long gone, has a story to tell about the nature of America at the time—not only about its transportational needs, but the availability of materials and the technological prowess of the people who built it. Illustrated with some 550 historical and contemporary photos, paintings, and technical drawings of nearly 400 different covered bridges, America's Covered Bridges offers five readable chapters on the history, design and fate of America's covered bridges, plus related bridges in Canada. Most of the contemporary photography is by master photographer A. Chester Ong of Hong Kong. 55 photo essays on the most iconic bridges including: Cornish-Windsor Bridge between Vermont and New Hampshire Porter-Parsonsfield Bridge, Maine East Paden and West Paden (Twin Bridges), Pennsylvania Philippi Bridge, West Virginia Hortons Mill Bridge, Alabama Medora Bridge, Indiana Rock Mill Bridge, Ohio Knight's Ferry Bridge, California Perrault Bridge, Quebec, Canada Hartland Bridge, New Brunswick, Canada Over time, wooden bridges eventually gave way to ones made of iron, steel and concrete. An American icon, many covered bridges became obsolete and were replaced—others simply decayed and collapsed. Many more were swept away by natural disasters and fires. America's Covered Bridges is absolutely packed with fascinating stories and information passionately told by two leading experts on this subject. The book will be of tremendous interest to anyone interested in American history, carpentry and technological change.
