Deflection of reinforced concrete beams strengthened with CFRP

Abstract

Abstract. This paper presents the results of an experimental study to investigate the deflection of reinforced concrete beams strengthened with external CFRP reinforcement. The influence of anchoring of external reinforcement was investigated. CFRP reinforcement was anchored in three different ways. Steel clamps, fibre wraps and steel pins were used for anchoring. Also different prepressing levels and different areas of steel clamps were used. The analysis of results of experimental research shows that anchoring of external reinforcement affects the performance and deflection of the strengthened reinforced concrete beams.
