Bending of concrete columns reinforced with FRP bars

Concrete poles for power distribution manufactured by centrifugation and prestressed with fibre-reinforced polymer reinforcement have proven to be efficient and economical in situations of accelerated deterioration of conventional poles in the coastal environment. The lack of standardized calculation procedures for the dimensioning of such elements, the modest base of experimental research, especially when it comes to the use of concrete with a reduced carbon footprint, along with the necessary condition of making a national technical assessment for placing it on the market, make greater commercial use difficult. Evaluating all column types of one manufacturer with different load capacities and heights in the process of attestation of conformity is near impossible and time-consuming procedure and would be replaced by the proposed numerical methods. The topic of paper contributes to the theoretical and experimental research of the described construction product.
