Bridge Maintenance, Safety, Management, Life-Cycle Sustainability and Innovations


Book Description

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.













Load Factors for Evaluating Permit Vehicles


Book Description

In recent years, requests to move heavy vehicles across bridges have risen dramatically. Highway agencies find it necessary to calculate safety margins under loads significantly above legal levels. For some regions of the U.S., permits have effectively raised the legal vehicle weight. Reliability analysis is used in this study to model live load uncertainties (using bridge weigh-in-motion data) and other dead load and resistance variables. Target safety indices are introduced by calibration with existing bridge rating and posting practices. Simulation of the expected maximum load effects of permit vehicles plus alongside vehicles has been carried out for both frequent permits, for different traffic classifications including volume and traffic enforcement levels, and single passage permits. Load factors are calibrated to achieve the target safety indices for different simple and continuous spans. A checking format for permit vehicles is proposed for possible inclusion in a bridge evaluation code. For the covering abstract of the Conference see IRRD Abstract No. 807839.
