Field Load Testing And Modeling Of A Strengthened
Timber Trestle Railroad Bridge

Abstract
In the United States many existing timber trestle railroad bridges have been in
service for between 40 to over 100 years. During that time period, train loads have
increased significantly. This paper describes the load tests of such a bridge before
and after it was strengthened and selected results and findings. Static, ramp, and
rolling train loads were used before the strengthening and rolling train tests were
used afterward. The goal is to better understand load paths, examine behavior
under current load levels, and examine the benefits of strength
