Claim One:
1. A method for live load rating of pile-supported bridges with known or unknown embedment depth using a hybrid analytical system, comprised of: determining a pile embedment of a pile supported bridge; using at least one of displacement gauges, stress sensors or strain sensors on at least one of piles or other substructure elements to determine a substructure load rating as vehicular traffic loads the bridge; using at least one of strain sensors or load cells at measurement locations on bridge superstructure elements to determine a superstructure load rating as vehicular traffic loads the bridge, wherein determining superstructure load rating, comprises applying a factor related to monitoring duration and bridge span length and continuity to relate a measured response to a response caused by a rating vehicle; calculating an overall bridge load rating by combining the substructure and the superstructure load ratings; and outputting the overall bridge load rating.
