Evaluation of Load Rating by Load and Resistance Factor Rating
Michael Baker, Jr., Inc.
NCHRP Report 700 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, AASHTO legal loads, and eight additional permit/legal vehicles. The report includes recommended revisions to the AASHTO Manual for Bridge Evaluation based on a review of the analysis results. The material in this report will be of immediate interest to bridge engineers.
