Available in PDF, EPUB and Kindle. Book excerpt: The ever increasing demands on the national infrastructure, along with the age, neglect, and misuse of many bridges throughout the country, have placed a great deal of strain on the States Departments of Transportation to maintain the country's bridges. While the current visual inspection process is able to access more obvious maintenance and repair needs, a more quantitative inspection will allow for a better understanding of bridge behavior and a more uniform inspection process. The In-Service Bridge Monitoring System (ISBMS) developed at the University of Delaware was designed with this process in mind. In this research, the ISBMS is used to gather strain data for up to two weeks on bridges throughout the state of Delaware. The in-service data is then used to project the maximum strain expected for a given return period. Rating factors based on the projected values are then calculated. Weigh-in-Motion (WIM) data is also collected for a number of the bridges in this study. The WIM data is used to find a correlation between truck weights and measured strain. After a correlation is found, rating factors based on the WIM data are then calculated. The in-service and WIM rating factors are finally compared to the rating factors used by the Delaware Department of Transportation and calculated in Bridge Rating and Analysis of Structural Systems (BRASS). The analysis in this study proves the usefulness of implementing the ISBMS into the routine biennial inspection process. The data gained from the system is invaluable in evaluating the overall safety of bridges. The conservative nature of the current rating factor equations is also revealed. By collecting in-service data, states will have a better understanding of their bridges under site-specific loading. This will allow for a better allocation of the limited time and funds available for bridge maintenance and repair. By implementing in-service monitoring into the current inspection process overall bridge safety and infrastructure reliability will be improved.

This book was released on 2017 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis is dealing with the influence of number and quality of weigh-in-motion (WIM) data to calculate load effects on bridges. Weighing in motion is the only method that provides continuous and unbiased information on traffic loads, but the data contains errors as a result of environmental influences and measurements that can not be constantly monitored. Presented are improvements of bridge WIM technology, which replaces the weighing sensors in the road surface with instrumented bridge superstructures. The system had many advantages, but also shortcomings that prevented its long-term installations. Proposed are a new installation procedure for the sensors that detect axles of the vehicles, a new way of calculating the influence lines, which is based on the responses of crossing vehicles, a method that deals with measurement errors caused by cracks in concrete, and a procedure that takes into account the impact of temperature on the behaviour of bridges. Also shown is the procedure to determine the dynamic loads that the commercial vehicles induce, and their impact on the measurement results. The following chapter elaborates quality control of bridge WIM data. The proposed procedures check and correct typical errors that occur during the measurements, assess quality and reliability of data and significantly shorten the time needed for its verification. Simulation procedures, which are predominantly used for calculating the traffic load effects on bridges, are complex and time intensive. The convolution method, a less demanding procedure appropriate for short to medium-span bridges, was thoroughly investigated. The results were compared with the ones obtained by comprehensive simulations. Convolution method has facilitated the detailed analysis of the impact of quantity and quality of WIM data on calculated moments and shear forces, for simply supported bridges with spans between 5 and 45 meters, which represent the vast majority of all bridges. The size of data samples was varied to investigate its influence on the load effects. Then, various data sources, with respect to quality of data (measured, electronically corrected, visually verified), were examined. The results give clear indications about the required number and quality of WIM data for effective modelling of traffic loads on bridges.

This book was released on 2010-05 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weigh-in-Motion (WIM) data can be used to predict future traffic volumes and weights for the planning of new infrastructure, the management of maintenance activities, the identification/reduction of overloading problems and the evaluation of the performance of pavements and bridges. Most WIM systems are based on sensors placed in or on the pavement that measure the wheel force applied over them during a very short time. The value of this force varies as a result of road roughness and vehicle dynamics leading to limited accuracy for estimating static weights. Additionally, these systems experience durability problems due to traffic and environmental conditions. An alternative approach to WIM that addresses these limitations is the use of an instrumented bridge to weigh vehicles (B-WIM). This approach is the subject of research in this book. Inaccuracies derived from discrepancies between theoretical B-WIM algorithms and bridge measurements are investigated both theoretically and experimentally. The text also describes the development of a B-WIM system in Ireland, including all aspects of installation, calibration, data collection and its processing into useful traffic information.

This book was released on 2018-05-08 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the development in global economic and transportation engineering, the traffic loads on brides have been growing steadily, which become potential safety hazards for existing bridges. In particular, long-span suspension bridges support heavy traffic volumes and simultaneous truck loads on the bridge deck, and thus the safety and serviceability of the bridge deserves investigation. In this book, a multiscale reliability method is presented for the safety assessment of long-span bridges. The multiscale failure condition of stiffness girders is the first-passage criteria for the large-scale model and the fatigue damage criteria for the small-scale model. It is the objective of this book to provide a more in-depth understanding of the vehicle-bridge interaction from the random vibration perspective. This book is suitable for adoption as a text book or a reference book in an advanced structural reliability analysis course. Furthermore, this book also provides a theoretical foundation for better understanding of the safety assessment, operation management, maintenance and reinforcement for long-span bridges and motivates further research and development for more advanced reliability and serviceability assessment techniques for long-span bridges.

Available in PDF, EPUB and Kindle. Book excerpt: Weigh-in-motion data collected in Australia and Canada have been analysed to obtain the distributions of midspan moment in simply supported beams with spans between 10 and 40 m. these moments are used to demonstrate the concept of a bridge site index. This concept enables moments for a particular recurrence interval to be predicted with reasonable accuracy from a single number, the bridge site index. A relationship is developed between this bridge site index and the Ontario legal limits which are based on the Ontario equivalent base length concept. Applications such as data summary, site ranking, bridge evaluation, fatigue, and bridge management are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
