Book Synopsis Review of Load Rating and Posting Procedures and Requirements by : Mark Bowen
Download or read book Review of Load Rating and Posting Procedures and Requirements written by Mark Bowen and published by . This book was released on 2014-12-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Nondestructive Condition Assessment of a Posted Bridge written by and published by . This book was released on 1997 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are about five hundred steel-truss highway bridges in Ohio, as well as many thousands in the nation, which are more than seventy-five years old. Preservation of aged historic steel-truss bridges first requires a consideration of public safety issues. Bridges with certain structural attributes and materials are well established as having non desirable failure modes, which make them public safety hazards. These should be removed from service with the highest possible priority. If non-technical issues such as historic significance and functional adequacy are favorable, the question then becomes whether a given bridge can be preserved within the available financial and technical resources of the responsible government agency.

Book Synopsis Reliability-based Condition Assessment of Existing Highway Bridges by : Naiyu Wang
Download or read book Reliability-based Condition Assessment of Existing Highway Bridges written by Naiyu Wang and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Condition assessment and safety verification of existing bridges and decisions as to whether bridge posting is required are addressed through analysis, load testing, or a combination of methods. Bridge rating through structural analysis is by far the most common procedure for rating existing bridges. The American Association of State Highway and Transportation Officials (AASHTO) Manual for Bridge Evaluation (MBE), First Edition permits bridge capacity ratings to be determined through allowable stress rating (ASR), load factor rating (LFR) or load and resistance factor rating (LRFR); the latter method is keyed to the AASHTO LRFD Bridge Design Specifications, which is reliability-based and has been required for the design of new bridges built with federal findings since October, 2007. A survey of current bridge rating practices in the United States has revealed that these three methods may lead to different ratings and posting limits for the same bridge, a situation that carries serious implications with regard to the safety of the public and the economic well-being of communities that may be affected by bridge postings or closures. To address this issue, a research program has been conducted with the overall objective of providing recommendations for improving the process by which the condition of existing bridge structures is assessed. This research required a coordinated program of load testing and finite element analysis of selected bridges in the State of Georgia to gain perspectives on the behavior of older bridges under various load conditions. Structural system reliability assessments of these bridges were conducted and bridge fragilities were developed for purposes of comparison with component reliability benchmarks for new bridges. A reliability-based bridge rating framework was developed, along with a series of recommended improvements to the current bridge rating methods, which facilitate the incorporation of various in situ conditions of existing bridges into the bridge rating process at both component and system levels. This framework permits bridge ratings to be conducted at three levels of increasing complexity to achieve the performance objectives, expressed in the terms of reliability, that are embedded in the LRFR option of the AASHTO Manual of Bridge Evaluation. This research was sponsored by the Georgia Department of Transportation, and has led to a set of Recommended Guidelines for Condition Assessment and Evaluation of Existing Bridges in Georgia.

Book Synopsis Parametric Study for Assessment of Bridges to Meet Specialized Hauling Vehicle Requirements in Ohio by : Himal Gyawali
Download or read book Parametric Study for Assessment of Bridges to Meet Specialized Hauling Vehicle Requirements in Ohio written by Himal Gyawali and published by . This book was released on 2018 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the FHWA (Federal Highway Administration) memo dated November 15, 2013, state Departments of Transportation (DOTs) are required to incorporate SHVs (Special Hauling Vehicles) in their load rating scheme and, if necessary, post bridges. Ohio-DOT uses its own set of legal trucks (2F1, 3F1, F1 and 5C1) in place of AASHTO (American Association of State Highway and Transportation Officials) type 3, 3-S2, and 3-3 legal trucks for load rating. A comparison of moments produced by the AASHTO SHVs showed an increase of up to 25\% over the Ohio legal trucks. To reduce the population of total bridges to be load rated for SHVs, it was hypothesized that Ohio bridges with a span of less than 200 feet, and a rating factor (RF) greater than or equal to 1.35 for Ohio legal loads, will have a load rating factor greater than 1.00 under the new SHV loads. This thesis presents the research work to assist ODOT (Ohio Department of Transportation) in parametrically demonstrating the above-mentioned hypothesis. The parametric study examines theoretical single and multiple span bridges of uniform stiffness. For the parametric study of simple span bridges, the ratio of controlling RFs increased from fifteen to eighty feet, having 1.35 ratio at a span of seventy feet, and a maximum ratio of 1.36 for spans eighty feet followed by a decreasing trend. A ratio of 1.36 meant the controlling RF for SHV could fall to 0.99 for a bridge if its controlling RF for Ohio legal load is 1.35. Shear did not control in any of the cases The parametric study of multi-span bridges was done in two stages. Since thousands of span combinations were possible in the inventory, the first stage was to find the most conservative span configurations. It was found that two-span bridges are more conservative than other multi-span configurations, except for negative moment when the ratio of exterior to interior span is equal to or greater than 0.96. When the ratio of exterior to interior span is greater than or equal to 0.96, positive moment controls over negative moment. Therefore, a two-span bridge configuration always produces conservative load rating results. Analysis was performed only on a series of theoretical two-span bridges. The second stage of the parametric analysis was to evaluate the ratio of controlling RFs for the series of two span configurations. For multi-span bridges, none of the ratios of RF fall below 1.35 for positive moment and the critical configuration was eighty-five feet-fifty-five feet which had a rating factor of 1.35. The critical ratio of RF for negative moment was found to be 1.37 for a 30 feet-20 feet span.
