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.
