Improved Ratings for Covered Bridges by Load Testing

This study will develop and establish new load-rating procedures (based upon live-load vehicle testing) for reliably determining safe load-carrying capacity of historic covered bridges.

A comprehensive final report will document recommended procedures for live-load testing and enhanced load rating of historic covered bridges. The final report will include recommendations for (a) setting the maximum experimental load that can be safely applied to the structure; (b) methods of loading the bridge; (c) selection and placement of instrumentation; (d) procedures for ensuring quality data; and (e) procedures to analyze collected data and establish load ratings. These recommendations will be prepared in a format similar to existing rating guides.
