Author: Mlynarski, Mark | Size: 0.99 MB | Format: PDF | Quality: Original preprint | Publisher: Transportation Research Board | Year: 2011 | pages: 101 | ISBN: 9780309213448

This report documents an analysis of 1,500 bridges that represent various material types and configurations using AASHTOWare™ 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 proposed 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.
