Simplified Bridge Load Rating Methodology Using the National Bridge Inventory File. Volume 1. Users Manual
The purpose of the research was to develop a computerized system to determine the adequacy of a bridge or group of bridges to carry specified overload vehicles. The system utilizes two levels of analysis. The Level 1 analysis is the basic rating system for the Arizona Department of Transportation. The analysis computes the overload capacity with a limited amount of data. A Level 2 evaluation, which conducts a more detailed evaluation, uses an enhanced NBIF database, Standard Plans, or a more detailed analysis similar to Brass. A Special Level 2 analysis was also developed to analyze continuous slab bridges by utilizing data from standard slab plans. Detailed case studies were conducted on twenty-five typical Arizona bridges to verify the methodology used in the Level 1 procedure and to correlate the bridge plans with data in the NBIF. The Level 1 procedure gives ratings which are within 10% of the Level 2 procedure for bridges which satisfy the level one assumptions. Similarly, the Special Level 2 analysis for reinforced concrete continuous bridges gives ratings within 10% of the Level 2 analysis. The NBIF compared well with general bridge plans and is applicable to Level 1 analysis for typical bridges.
