Guidance on Protecting and Extending the Life of Suspension BridgesSuspension bridges are graceful, aesthetic, and iconic structures. Due to their attractiveness and visibility, they are well-known symbols of major cities and countries in the world. They are also an essential form of transportation infrastructure built across large bodies of water. Despite being expensive to build, they are economical structures for the lengths they span. They have evolved significantly from the basic concept dating back to 200 BC China through the first design for a bridge resembling a modern suspension bridge, attributed to Fausto Veranzio in 1595, to present-day span lengths close to two kilometers.Many of these bridges carry significant traffic and their upkeep is very important to maintain transportation mobility. They offer grace and functionality, yet are extremely complex to construct and maintain. Bridge owners spend a considerable amount of time and resources to ensure uninterrupted service, safety, and security for users. Inspection, evaluation, maintenance, and rehabilitation have evolved significantly. Modern materials and innovative design and construction practices have been integrated into these bridges to maintain durability and extended service life. Captures the Experience of More Than 20 Suspension Bridge OperatorsInspection, Evaluation and Maintenance of Suspension Bridges is written by the bridge owners and practitioners who strive to cost-effectively manage these bridges. It is invaluable to everyone interested not only in suspension bridges but in the upkeep of any bridges—students, designers, maintenance personnel, contractors, and owners. Describes the evolution and trends in the operation and maintenance of cable supported bridges Contains the latest methods for evaluating cable supported bridge capacities and durability Presents suspension bridge security risk management aspects and Bayesian network-based methodology for risk evaluation This volume discusses state-of-the-art practice in suspension bridge inspection, evaluation, and rehabilitation methods used worldwide, described by the personnel directly involved with managing them. Its companion volume presents detailed case studies of specific bridges to give a comprehensive picture of how suspension bridges are maintained around the world.

Continually increasing demands on infrastructures mean that maintenance and renewal require timely, appropriate action that maximizes benefits while minimizing cost. To be as well informed as possible, decision-makers must have an optimal understanding of an infrastructure’s condition—what it is now, and what it is expected to be in the future. Written by two highly respected engineers, the second volume, Infrastructure Health in Civil Engineering: Applications and Management, integrates the decision making concept into theoretical and practical issues. It covers: State-of-the-art practice and future directions Use of probability and statistics in areas including structural modeling Specific practical applications, including retrofitting and rehabilitation in response to earthquake damage, corrosion, fatigue, and bridge security Use of IHCE for management and maintenance of different types of structures using pre-stressed and reinforced concrete, and fiber-reinforced polymers (FRPs) Numerous practical case studies, as well as coverage of the latest techniques in the use of sensors for damage detection and load testing Built to correspond to the ideas presented in its companion volume, Theory and Components, this is an invaluable guide to optimized, cost-saving methods that will help readers meet safety specifications for new projects, as well as the aging infrastructure at great risk of failure.

This book explains and presents the need for Multihazard Consideration (MH) in the management of civil infrastructure, what constitutes MH, and how to address MH in design and analysis. A generalized theory of MH will serve as the basis of the objective treatment of this volume. Use of MH in bridge management (inspection, maintenance, rehabilitation, and replacement) will serve as the basis for several examples, and numerous case studies will be presented throughout.
