Loading composite utility poles to failure to understand failure modes
New and aged composite poles from each manufacturer were loaded to failure to compare how their mechanical properties change over time, and the types of failure characteristics experienced. It should be noted that poles from the various manufacturers were not selected based on equivalent performance. Video shows testing of poles in their new condition. Equivalent poles were subjected to accelerated aging for 3 years and then subjected to identical testing to identify any changes in ultimate load and deflection.
