Strength and deflection behavior of spun concrete poles with CFRP reinforcement

Academic Article

Abstract

  • Prestressed spun concrete poles are used primarily for supporting electric power transmission lines and distribution and for area lighting.many applications they are placed directly in brackish water or saltwater, resulting in deterioration of the concrete pole due to steel corrosion. A new type of reinforcement that can provide the desired structural characteristics and at the same time address the issue of corrosion is needed. Carbon fiber-reinforced polymer (CFRP) composites show potential as a replacement for steel reinforcement because of their corrosion resistance, high strength, and light weight that enables easier handling and reduces the self-weight of structures. The main objective of the research was to study the strength and deflection behavior of spun concrete poles with CFRP reinforcing bars. The study showed that the performance of the poles reinforced with CFRP bars was satisfactory under bending loads, which are the primary governing loads in most applications.
