| Abstract: |
This paper presents results of a theoretical study to evaluate the ductility of reinforced concrete beams strengthened in flexure with externally bonded carbon fibre reinforced polymers (CFRPs). Research into the design of flexural strengthening of concrete structures with carbon fibre composites (CFC) is well known, but understanding of the beams’ ductility behaviour has yet to reach the same level. The main objective of this investigation is to discover a new and consistent approach towards the ductility of reinforced concrete beams flexurally strengthened by carbon fibre composites. The need to clarify the behaviour of CRFP strengthened beams is defined as a new energetic index based on the strain energy of the deformed beam. The ductility is evaluated by using the energy indexes obtained from the curves for load vs. Deflection, and bending moment vs. Curvature. |
