Download or read book Live Load Rating of Short Span Highway Bridges as Controlled by the Exterior Girder written by H. L. Kinnier and published by . This book was released on 1977 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1973 AASHTO Standard Specifications for Highway Bridge introduced the requirement that "In no case shall an exterior stringer have less carrying capacity than an interior stringer." This statement resulted from the concern that many original exterior stringers became interior stringers when bridges were widened. Since current specifications are used when rating live load capacity of existing bridges, this newly introduced requirement has in some cases resulted in an unnecessary reduction in live load ratings. This study examines a number of cases in which exterior stringers are lighter than the interior ones and illustrates the effects of the new provision. The report concludes with a recommendation from an exemption provision from this requirement in the appropriate article of the Manual for Inspection Maintenance of bridges, 1974, 2nd ed., AASHTO.

Book excerpt: 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
Download or read book Methods for Increasing Live Load Capacity of Existing Highway Bridges written by Roger A. Dorton and published by Transportation Research Board. This book was released on 1997 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Bridge Traffic Loading written by Eugene OBrien and published by CRC Press. This book was released on 2021-12-03 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is considerable uncertainty about what level of traffic loading bridges should be designed for. Codes specify notional load models, generally to represent extreme levels of normal traffic, but these are often crude and have inconsistent levels of safety for different load effects. Over the past few decades, increasing quantities of reliable truck weight data has become available and it is now possible to calculate appropriate levels of bridge traffic loading, both for specific bridges and for a road network. Bridge Traffic Loading brings together experts from all over the world to deliver not just the state-of-the-art of vertical loading, but also to provide recommendations of best-practice for all the major challenges in the field – short-span, single and multi-lane bridge loading, dynamic allowance and long-span bridges. It reviews issues that continue to be debated, such as which statistical distribution is most appropriate, whether free-flowing or congested traffic governs and dealing with future traffic growth. Specialist consultants and bridge owners should find this invaluable, as will regulators.

This book was released on 2002 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: There exists in the state of Ohio a large inventory of short span reinforced concrete bridges, particularly on rural secondary highways, whose actual structural reliability cannot be accurately ascertained. Quite often little or no documentation exists to assist the responsible local jurisdictions in assessing the ability of these bridges to safely carry modern truck loading.

Available in PDF, EPUB and Kindle. Book excerpt: A mean stress range histogram and corresponding frequency distribution function for single truck crossings over short-span highway bridges, derived from 106 published histograms, is proposed. A major portion of this load history was applied to a welded transverse stiffener detail in blocks varying from 100 cycles to 100 000 cycles. When the number of cycles in the block was 1000 cycles or less, the block size had no significant effect on the total number of cycles to failure. Block loading simulated then random loading, and the root-mean-cube stress range provided a reasonable transfer function between block loading and constant amplitude cycling.

Available in PDF, EPUB and Kindle. Book excerpt: Load Testing of Bridges, featuring contributions from almost fifty authors from around the world across two interrelated volumes, deals with the practical aspects, the scientific developments, and the international views on the topic of load testing of bridges. Volume 12, Load Testing of Bridges: Current practice and Diagnostic Load Testing, starts with a background to bridge load testing, including the historical perspectives and evolutions, and the current codes and guidelines that are governing in countries around the world. The second part of the book deals with preparation, execution, and post-processing of load tests on bridges. The third part focuses on diagnostic load testing of bridges. Volume 13, Load Testing of Bridges: Proof Load Testing and the Future of Load Testing, focuses first on proof load testing of bridges. It discusses the specific aspects of proof load testing during the preparation, execution, and post-processing of such a test (Part 1). The second part covers the testing of buildings. The third part discusses novel ideas regarding measurement techniques used for load testing. Methods using non-contact sensors, such as photography- and video-based measurement techniques are discussed. The fourth part discusses load testing in the framework of reliability-based decision-making and in the framework of a bridge management program. The final part of the book summarizes the knowledge presented across the two volumes, as well as the remaining open questions for research, and provides practical recommendations for engineers carrying out load tests. This work will be of interest to researchers and academics in the field of civil/structural engineering, practicing engineers and road authorities worldwide.
