LRFR Methodology for Missouri Bridges
| 项目名称： | LRFR Methodology for Missouri Bridges |
| 摘要： | Load and Resistance Factor Rating, also referred to as LRFR, is an American Association of State Highway and Transportation Officials (AASHTO)-adopted guide manual for the condition evaluation of bridge structures. Missouri Department of Transportation (MoDOT) has recently updated their load rating policy to better reflect the wide range of heavier vehicles legally travelling along Missouri roads. These updated rating practices are predominately based on the Load Factor Rating (LFR) methodology, with the allowance for the allowable stress rating methodology in special situations (example is timber bridges). The updated rating practices also includes the LRFR methodology for general load ratings, but not for load posting determinations. MoDOT would like to implement load posting policy with the LRFR methodology that is consistent with their current policy using LFR and provides similar results in terms of the number of bridges requiring load postings. The Research Team will provide MoDOT with recommendations of LRFR adoption. |
