Abstract text:
This paper presents the organization of an experimental study on the efficiency of near surface mounted (NSM) carbon fibre reinforced polymer (CFRP) reinforcement for the flexural strengthening of reinforced concrete (RC) beams. Four series of three beams each, having the same cross section and longitudinal tensile steel reinforcement, are investigated. The shear reinforcement is designed so that flexural failure will prevail. First and second series are strengthened with CFRP bars. For the third and the fourth series CFRP strips are used for strengthening. One reference beam is realized without any strengthening. The experiment setup of the RC beams allows determining the overall stiffness and flexural capacity of the strengthened specimens in comparison to the reference one.
Key Words:
near surface mounted; carbon fibre reinforced polymer; reinforced concrete; composite strips.
