Calibration of Load Factors for LFRD Bridge Evaluation
INTRODUCTION
This report presents the derivations of the live load factors
and associated checking criteria incorporated in the proposed
Manual for Condition Evaluation and Load and Resistance
Factor Rating of Highway Bridges prepared for NCHRP Project 12-
46 (hereafter referred to as the Evaluation Manual). A
final draft of this Evaluation Manual was submitted early in
2000 to the project panel and to appropriate AASHTO
committees. In addition, there is a companion project report
(prepared by Lichtenstein Consulting Engineers, Inc.), which
contains trial ratings, numerous bridge examples, and comparisons
of proposed and existing rating results.
