On Thursday evening, May 23, 2013, the Interstate 5 Bridge over the Skagit River in Washington state collapsed due to impact by an oversize truck, dumping vehicles and people into the water. Fortunately, the bridge is located in a rural area and nobody was killed in the accident, but three people were rescued after their cars plunged into the frigid water of the Skagit River. According to Washington state officials, the bridge was inspected last year and was not structurally deficient, but collapsed because of apparent impact from an oversize truck. Nevertheless, the collapse of the steel truss bridge renewed appeals for greater investment in the nation’s aging infrastructure. These appeals are echoed throughout the bridge engineering community worldwide, as the condition of deteriorated bridges worsens with increasing traffic loads combined with lack of proper maintenance. Bridge engineers from different countries shared their experience toward achieving durable bridge structures, during the 7th New York City Bridge Conference, held on August 26-27, 2013. This book contains select papers that were presented at the conference. These peer-reviewed papers are valuable contributions and of archival quality in bridge engineering.
Describes several bridging concepts, which were developed and successfully applied during the author's forty years of close involvement with UK and international bridge design, construction, maintenance and research. The concepts mainly apply to the small/medium span range of bridges and viaducts.
This volume deals with the most modern and topical problems of bridge design. The topics presented allow to tackle both theoretical-analytical as well as technical-constructive aspects of the design problem, pointing out how in the case of bridges, specifically for long span bridges, the two aspects are absolutely inseparable. In modern bridges, reasons of technical and economic feasibility oblige an extreme parceling of the construction process, with the consequent need to revise, with respect to the past, both design concepts as well as the theoretical apparatus of analysis that governs it. All this can clearly be derived from reading the present volume, in which the different contributions stress theoretical and technical questions of particular interest and topicality, without claiming to approach them systematically, but offering clear procedural rules and trend indications. With reference to the theoretical approach, some of particular importance are reviewed, such as the possibility of using limit analysis, the simplification of the design process for bridges, durability, and computer aided design. For what concerns the bridge typologies and the corresponding constructive problems, the emphasis is mostly on the ones still in an evolutionary phase, that is long span suspended/stayed bridges and cantilever built bridges with prefabricated segments.
Sustainable and durable infrastructure facilities, including bridges, require optimum use of all resources involving reduction of energy and water consumption during all project phases, including planning, design, construction, maintenance, operations, repair and rehabilitation, and finally decommissioning and disposal of the debris at the end of its service life. Design of a sustainable and durable bridge structure requires consideration of a few feasible alternatives to develop an optimum option to fulfill all of the relevant limit states, with the best life-cycle performance and with the lowest life-cycle costs. The current national standards do not account for the observed increases in operating loads and the increasing deterioration of bridge structures over their service life. While these standards emphasize quality control in choice of materials, design and construction, they do not provide guidance and scientific tools to design and maintain a bridge ...
Bridge Maintenance, Safety, Management, Life-Cycle Sustainability and Innovations contains lectures and papers presented at the Tenth International Conference on Bridge Maintenance, Safety and Management (IABMAS 2020), held in Sapporo, Hokkaido, Japan, April 11–15, 2021. This volume consists of a book of extended abstracts and a USB card containing the full papers of 571 contributions presented at IABMAS 2020, including the T.Y. Lin Lecture, 9 Keynote Lectures, and 561 technical papers from 40 countries. The contributions presented at IABMAS 2020 deal with the state of the art as well as emerging concepts and innovative applications related to the main aspects of maintenance, safety, management, life-cycle sustainability and technological innovations of bridges. Major topics include: advanced bridge design, construction and maintenance approaches, safety, reliability and risk evaluation, life-cycle management, life-cycle sustainability, standardization, analytical models, bridge management systems, service life prediction, maintenance and management strategies, structural health monitoring, non-destructive testing and field testing, safety, resilience, robustness and redundancy, durability enhancement, repair and rehabilitation, fatigue and corrosion, extreme loads, and application of information and computer technology and artificial intelligence for bridges, among others. This volume provides both an up-to-date overview of the field of bridge engineering and significant contributions to the process of making more rational decisions on maintenance, safety, management, life-cycle sustainability and technological innovations of bridges for the purpose of enhancing the welfare of society. The Editors hope that these Proceedings will serve as a valuable reference to all concerned with bridge structure and infrastructure systems, including engineers, researchers, academics and students from all areas of bridge engineering.
The ever-increasing traffic demands, coupled with deteriorating condition of bridge structures, present great challenges for maintaining a healthy transportation network. The challenges encompass a wide range of economic, environmental, and social constraints that go beyond the technical boundaries of bridge engineering. Those constraints compound
This book covers topics relevant to the concept of infrastructure construction, including key requirements of development such as measuring productivity and maintenance. It presents different categories of sustainability maintenance of critical infrastructures. In addition, it presents a complex simulation model, the reconfiguration simulator, which enables evaluation of the effectiveness of resilience enhancement strategies for electric distribution networks and the required resources to implement them. Then, it discusses health services as a critical sector in this field, which should be able to perform its function, even in times of crisis. The last chapter presents a brief review of different bridges, including the processes of design, material selection, construction, and maintenance.
Innovative Bridge Design Handbook: Construction, Rehabilitation, and Maintenance, Second Edition, brings together the essentials of bridge engineering across design, assessment, research and construction.
