Guide manual for condition evaluation and load and resistance factor rating

Evaluation of Bridges and the Guide Manual for Condition Evaluation and Load and Resistance Factor Rating of Highway Bridges (LRFR Manual), we believe that it is necessary to accommodate and support Load and Resistance Factor Rating (LRFR), while continuing to accept Load Factor Rating (LFR) for the large inventory of in-service bridges that have been designed by another method other .  · This paper introduces the American Association of State Highway Officials’ (AASHTO) new Guide Manual for Condition Evaluation and Load and Resistance Factor Rating of Highway Bridges that was completed in March under a National Cooperative Highway Research Program research project and adopted as a Guide Manual by the . Manual for Condition Evaluation and Load and Resistance Factor Rating of Highway Bridges. This report also contains the details of the project history; this includes the testing phase that was part of the project and comments by the States and responses by the Research Team (in section 3).

The new Manual is a companion document to the AASHTO Load and Resistance Factor Design (LRFD) Bridge Design Specifications in the same manner that the current Manual for Condition Evaluation of Bridges is to the AASHTO Standard Specifications. The new Manual is consistent with the LRFD Specifications in using a reliability based limit states philosophy and extends the provisions of the LRFD Specifications to the areas of inspection, load rating, posting and permit rules, fatigue evaluation. The Draft Manual for the Condition Evaluation and Load and Resistance Factor Rating of Highway Bridges was developed under NCHRP Project The Manual, and in particular the section on load rating have been extensively reviewed by Technical Committee T, Bridge Management Evaluation and Rehabilitation. Evaluation of Bridges and the Guide Manual for Condition Evaluation and Load and Resistance Factor Rating of Highway Bridges (LRFR Manual), we believe that it is necessary to accommodate and support Load and Resistance Factor Rating (LRFR), while continuing to accept Load Factor Rating (LFR) for the large inventory of in-service bridges that have been designed by another method other than LRFD.
