Abstract:

The Load and Resistance Factor Rating (LRFR) code for load rating bridges is based on factors calibrated from structural ; load and resistance statistics to achieve a more uniform level of reliability for all bridges. The liveload factors in the ; LRFR code are based on load data thought to be representative of heavy truck traffic nationwide. However, the code ; allows for recalibrating liveload factors for a jurisdiction if weigh-in-motion data of sufficient quality and quantity are ; available. The Oregon Department of Transportation is implementing customized liveload factors based on the analysis ; described in this report. The relatively low liveload factors obtained in the Oregon calibration are a logical outcome of the ; regulatory and enforcement environment in Oregon.
