Design and evaluation of large scale pultruded fiberglas tubular structures
Large solid wood structures have been used in structural applications such as utility poles and marine piling for a long time. A pultruded fiberglass reinforced polymer composite utility pole has been designed by the Composite Power Corparation of Las Vegas, Nevada, which meets or exceeds the wood pole strength standards. This type of pole has many advantages over traditional wood, metal or concrete poles including: lighter weight, easier to climb and service, better dielectric and fire resistance properties, and it is more environmentally sound than treated wood poles. Utility crossarms, other attachments, and climbing devices are secured to grooves which run the entire length of the pole so there is no need to drill holes or wear spiked boots which would compromise the strength of the pole. Bending and torsion experiments have been conducted to determine if the present design meets the strength requirements of a forty foot Class one wood pole. Initial results of the composite pole tests showed a 17 percent advantage in bending strength, a 449 percent advantage in strength due to a vertical load applied to a crossarm, and a 43 percent advantage in twisting strength. Plans for futher material characerization experiments and detailed stress and failure analysis are discussed.
