Re-evaluation of Weight Limits for Six Bridges in Montgomery County Maryland

摘要

Montgomery County, Maryland, owns and maintains 279 bridges. As a pilot program for re-evaluating weight postings, six of the 74 weight restricted bridges were selected for an advanced analysis through combined field load testing and finite element analysis. The project was successfully completed in 2005 and the work procedure and results are summarized in this paper. As a result of this project, weight postings of all six bridges have been removed.
