The main objectives of this research are to 1) determine correlations between structural monitoring data and bridge condition, 2) develop analytical methods for processing and interpreting structural monitoring data, and 3) develop a model for predicting the remaining service life of structural members based on strain responses and other monitoring data.

The intended outcome of the project is to demonstrate the effect of bridge aging and deterioration on structural behavior and live load distribution. This knowledge will enable a more accurate estimation of demands experienced by girders which will lead to a more accurate evaluation of bridge load-carrying performance and may provide evidence for a revision of load distribution methods for design analysis.
