Title: PROOF LOAD FORMULA FOR HIGHWAY BRIDGE RATING
Accession Number: 00627150
Record Type: Component
Availability: Find a library where document is available Abstract: A proof load formula is proposed for highway bridge evaluation through proof load testing to determine target proof load and load rating. This formula is based on a target structural safety index of 2.3, which is consistent with current bridge evaluation practice and also with an evaluation method of load and resistance factors under development. It is demonstrated that the proposed formula will ensure a relatively uniform level of bridge structural safety and that possible changes in input data and probability distribution assumptions in the reliability models will not affect the results obtained. This formula can be applied to highway bridge evaluation by proof load testing, and the resulting rating can be directly input to the current national bridge rating inventory. The formula may be included in specifications for highway bridge evaluation by proof testing.
