Analysis of the Effectiveness of Composite Longitudinal and Transverse Reinforcement to Increase the Strength and Rigidity of Flexible Non-centrally Compressed Reinforced Concrete Poles

The paper presents the results of studies to determine the effectiveness of composite longitudinal and transverse reinforcement in increasing the rigidity and strength of flexible non-centrally compressed reinforced concrete poles. Experimental data of strength, deflections and relative deformations of composite materials obtained by testing four reinforced concrete poles are presented. The effectiveness of composite reinforcement at ultimate strength and ultimate deflections has been evaluated. The relative deformations in composite materials were determined and the inclusion of the reinforcement system in the work of strengthened concrete reinforced specimens was evaluated. Based on the results obtained, the analysis was carried out and proposals for the design of reinforcement of flexible non-centrally compressed reinforced concrete poles operating with large eccentricities of the load application were developed.
