Evaluation of the Performance of a Press-lam Timber Bridge: Bridge Performance and Load Test After Five Years
Michael M. Sprinkel
Year: 1982
VTRC No.: 82-R56
Abstract: The report describes the results of the load tests and summarizes the collection of data on the dimensional changes and moisture content of the press-lain members and the number and types of vehicles using the bridge. The results of the load tests suggest that the AASHTO load distribution is conservative. Although the rails, wheel guards and posts are exhibiting a high moisture content and areas of delamination, the bridge is structurally sound and in excellent condition after five years of service.
