Book Description
The statistical study considered real bridges in Ohio with a rating factor (RF) ≥ 1.35 whose section properties may vary along the length of the bridge. A sample of these bridge was examined. The sample included a minimum of thirty bridges of the each of the six common types studied. No actual bridge was found to have an SHV RF

Book Description
The purpose of this project is to validate the draft New York State Department of Transportation LRFR Engineering Instruction developed to provide guidance on application of the LRFR methodology as specified in the AASHTO Manual for Bridge Evaluation to the evaluation of bridges in New York State through the testing of Level II and Level I ratings to support LRFR implementation. This report documents the Level I ratings of 23 complex bridges and culverts using 2D and 3D finite element (FE) analysis methods. Ratings and load posting evaluations were determined based on both EI 05-034 and the Draft LRFR EI to compare the results of the Load Factor Rating (LFR) and LRFR methodologies. The impact of LRFR ratings on load postings and R-postings for NYS bridges is evaluated. The report provides guidance in load rating and posting requirements of AASHTO Specialized Hauling Vehicles (SHVs) for both LFR and LRFR methodologies, proposes updates to the LFR based EI 05-034 “Load Rating/Posting Guidelines for State Owned Highway Bridges,” documents suggested “Load and Resistance Factor Rating (LRFR) Blue Pages,” describes an approach to derive LRFR Condition Factors using AASHTO element inspection data, and documents recommended revisions to the draft LRFR EI. In addition, a statewide bridge inventory screening for SHV and the FAST Act Emergency Vehicles (EV) is performed and the results are presented.

Book Description
TRB’s National Cooperative Highway Research Program (NCHRP) Report 700: A Comparison of AASHTO Bridge Load Rating Methods documents an analysis of 1,500 bridges that represent various material types and configurations using AASHTOWareTM Virtis® to compare the load factor rating to load and resistance factor rating for both moment and shear induced by design vehicles, American Association of State Highway and Transportation Officials (AASHTO) legal loads, and eight additional permit/legal vehicles.

Book Description
A load rating states the load in tons which a vehicle can impose on a bridge. Changes in guidelines, standards, and customary uses of bridges require analyses of bridges to be updated and reevaluated.
