Evaluation of the Performance of a Press-Lam Timber Bridge. Interim Report Number 2. Bridge Performance and Load Test After One Year

摘要

The report describes the installation of the wearing surface, the results of the second load test, and the status of the collection of data on the dimensional changes and moisture content of the press-lam members and the number and types of vehicles using the bridge. The results of the load test suggest that the AASHTO load distribution is conservative and that the steel dowels adequately provide for load transfer between panels. With the exception of the rails and wheel guards, which are exhibiting a high moisture content and showing signs of delamination, the bridge is structurally sound and in excellent condition after one year of service.
