Abstract

The response of FRP (Fiber Reinforced Polymer) reinforced concrete beam has been the topic of previous research, because of use of modern FRP composite materials in the building industry as concrete reinforcement. The behavior of FRP reinforced member is different from the one reinforced with regular steel reinforcement. This difference is caused by order of magnitude different moduli of elasticity of the respective materials and results in the fact that conventional design methods used for years in the field of reinforced concrete structures give poor results if used with FRP reinforced structural members. Results of conventional methods tend to overestimate load capacity of the member and underestimate deformations – both resulting in unsafe predictions. This paper points to formulating easy to use and comprehensible method of predicting moment capacity of FRP reinforced concrete beams subjected to bending loading, utilizing the bond-slip relation of the FRP reinforcement and validation of the proposed method via set of experiments.
