The University Transportation Research Center (UTRC) Publishes the Final Report: "Load and Resistance Factor Rating in New York State", a NYSDOT Funded Project

UTRC has released a set of two volumes final report on the research titled: "Load and Resistance Factor Rating in New York State" funded by the New York State Department of Transportation (NYSDOT) and the Research and Innovative Technology Administration (RITA/USDOT). The principal investigators were Dr. Anil Agrawal, Ph.D., and Dr. Michel Ghosn, Ph.D. from the Civil Engineering Department at the City College of New York.

The report develops a Load and Resistance Factor Rating (NYS-LRFR) methodology for New York bridges. The methodology is applicable for the rating of existing bridges, the posting of under-strength bridges, and checking Permit trucks. The proposed LRFR methodology is calibrated to provide uniform reliability index values for all applications. The reliability calibration of live load factors is based on live load models developed using Truck Weigh-In-Motion (WIM) data collected from several representative New York sites. The live load models provide statistical projections of the maximum live load effects expected on New York bridges.

The full report (two volumes) is available for a free download at the UTRC website:
