Wooden utility poles provide safe, economic, easily obtainable means of delivering power, communications, and cable television to the masses of industrial and residential locations worldwide. However, when a pole has been in service for a substantial number of years, its failure becomes more likely. Hence, the proposed project focuses on the strength estimation of in-service utility poles using non-destructive technology (NDT). The advantage of using NDT is that no further damage is caused to the poles during the investigation, which can further lead to reduced service life.
