Development of a Novel Pole Using Spun-Cast Concrete Inside Glass-Fiber-Reinforced Polymer Tubes

Poles are used in a variety of structural applications including utility, transmission, and distribution lines; telecommunications towers; street lighting; highway signage supports; rail electrification; and wind turbine supports. The traditional material used for manufacturing poles is wood, but alternatives have been sought as wood is becoming scarce and is susceptible to rotting or damage. Steel poles can also be used but are more expensive and need corrosion protection. Reinforced and prestressed concrete poles are now commonly used. This paper introduces a spun-cast concrete pole that uses a glass-fiber reinforced polymer (GFRP) tube to replace steel reinforcement. This new pole emerged after 2 types of poles were studied: a hollow GFRP tube that failed prematurely by local buckling and a completely filled GFRP tube that was greater in strength but heavier than the hollow tube. The feasibility of fabrication as well as the equivalent steel reinforcement required to match the strength of the GFRP tubes is demonstrated.
