Book Description
All states are required to load rate and post bridges in order to comply with federal standards. Load ratings are performed in order to determine the safe live load capacity of a bridge, considering the existing conditions of the bridge. Based on the load ratings, the bridge is evaluated for load posting or strengthening. The Indiana Department of Transportation (INDOT) was notified that their practice for load rating and posting did not satisfy 23 CFR 650.313. The purpose of this study was to summarize and compare load rating and posting procedures used in other states and to provide recommendations and information necessary to modify the load rating and posting procedures in INDOT's Bridge Inspection Manual (Part 3: Load Rating) in order to satisfy 23 CFR 650.313.In order to understand how load rating and posting is performed in other states, department of transportation (DOT) manuals were examined, questionnaires were sent to states, and additional states of interest were surveyed. The American Association of State Highway and Transportation Officials (AASHTO) The Manual for Bridge Evaluation, Second Edition, which is the current specification for load rating and posting bridges was reviewed, as well as older AASHTO bridge evaluation manuals. Based on this information, revisions were proposed to the INDOT Bridge Inspection Manual (Part 3: Load Rating) in order to eliminate current deficiencies.

Book Description
Evaluation, repair and rehabilitation of bridges are increasingly important topics in the effort to deal with the deteriorating infrastructure. For example, in the United States about 40 percent of the nation's 570,000 bridges are classified, according to the Federal Highway Administra tion's (FHW A) criteria, as deficient and in need of rehabilitation and replacement. In other countries the situation is similar. FHW A estimates the cost of a bridge replacement and reha bilitation program at 50 billion dollars. The major factors that have contributed to the present situation are: the age, inadequate maintenance, increasing load spectra and environmental contamination. The deficient bridges are posted, repaired or replaced. The disposition of bridges involves clear economical and safety implications. To avoid high costs of replacement or repair, the evaluation must accurately reveal the present load carrying capacity of the struc ture and predict loads and any further changes in the capacity (deterioration) in the applicable time span. Accuracy of bridge evaluation can be improved by using the recent developments in bridge diagnostics, structural tests, material tests, structural analysis and probabilistic methods. There is a need for an international exchange of advanced experience to increase the research effi ciency. The Workshop is organized on the premise that the exchange of existing American and European experience in the area of bridge evaluation, repair and rehabilitation is beneficial for both parties involved.

Book Description
This Manual has been developed to assist Bridge Owners by establishing inspection procedures And load rating practices that meet the National Bridge Inspection Standards (NBIS). The Manual has been divided into seven sections, with each section representing a distinct phase of an overall bridge inspection and load rating program. Section 1 contains introductory and background information on the maintenance inspection of bridges as well as definitions of general interest terms. Key components of a comprehensive bridge file are defined in Section 2. The record of each bridge in the file provides the foundation against which changes in physical condition can be measured. Changes in condition are determined by field inspections. The types and frequency of field inspections are discussed in Section 3 as well as specific inspection techniques and requirements. Conditions at a bridge site may require more elaborate material tests, and various testing methods are discussed in Section 4. Field load testing is a means of supplementing analytical procedures in determining the live load capacity of a bridge and for improving the confidence in the assumptions used in modeling the bridge. This is described in Section 5. Section 6 discusses the load rating of bridges and includes optional rating methods. The evaluation of fatigue and other special conditions are discussed in Section 7. The successful application of this Manual is directly related to the organizational structure established by the Bridge Owner. Such a structure should be both effective and responsive so that the unique characteristics and special problems of individual bridges are considered in developing an appropriate inspection plan and load capacity determination.

Book Description
This synthesis will be of interest to state department of transportation bridge design and structural engineers, bridge consultants, and others involved in applied and research methods for increasing the live load capacity of existing highway bridges. The synthesis describes the current state of the practice for the various methods used to increase the live load capacity of existing highway bridges. This is done predominantly for bridges in the short- to medium-span range. Information on the more common bridge material types is presented. There is an emphasis on superstructure rather than substructure strengthening.

Book Description
LOAD RATING HIGHWAY BRIDGES In accordance with Load and Resistance Factor Rating Method First Edition The first comprehensive text introducing the background theory along with the practical procedure of load rating highway bridges with the state-of-the-art Load and Resistance Factor Rating (LRFR) method. With its simplicity and complete contents on this subject, this is an indispensable text for both students and practicing engineers. The safety of bridges is essential to the traveling public. To ensure that bridges in our highway system function safely and serve properly, engineers need to inspect and assess the live load carrying capacity of the bridges. Based on the results of inspection and evaluation, decisions are made on load restriction, repair, retrofit or replacement. Load rating, one of the critical tasks in this decision-making process, uses either an analytical method or non-destructive load testing to determine the live load carrying capacity of a bridge. This is a book solely concentrated on bridge load rating by using analytical load rating methods, with a focus on the LRFR method. The primary purpose of this book is to provide the basic concept of load rating highway bridges in terms of the LRFR method. The target readers are practicing engineers who want to acquire fundamental knowledge of the LRFR method. Bearing that in mind, the author attempts to strike a balance between theory and how-to. Engineers who are conducting or will perform load ratings of bridges can use this text as a reference in supplement to the AASHTO Manual for Bridge Evaluation (MBE). This book can also serve as a textbook or supplemental material for a senior level undergraduate or graduate course in bridge design and load rating. This text is divided into three major sections. The first section contains a brief introduction to bridge load rating (Chapter 1) and fundamentals of structural failure and structural reliability theory (Chapter 2). After completing this section, re

Book Description
A succinct, real-world approach to complete bridge system design and evaluation Load and Resistance Factor Design (LRFD) and Load and Resistance Factor Rating (LRFR) are design and evaluation methods that have replaced or offered alternatives to other traditional methods as the new standards for designing and load-rating U.S. highway bridges. Bridge Design and Evaluation covers complete bridge systems (substructure and superstructure) in one succinct, manageable package. It presents real-world bridge examples demonstrating both their design and evaluation using LRFD and LRFR. Designed for a 3- to 4-credit undergraduate or graduate-level course, it presents the fundamentals of the topic without expanding needlessly into advanced or specialized topics. Important features include: Exclusive focus on LRFD and LRFR Hundreds of photographs and figures of real bridges to connect the theoretical with the practical Design and evaluation examples from real bridges including actual bridge plans and drawings and design methodologies Numerous exercise problems Specific design for a 3- to 4-credit course at the undergraduate or graduate level The only bridge engineering textbook to cover the important topics of bridge evaluation and rating Bridge Design and Evaluation is the most up-to-date and inclusive introduction available for students in civil engineering specializing in structural and transportation engineering.
