Abstract
This paper presents the results of static and fatigue tests of RC beams strengthened with tensioned CFRP plate. This plate was fabricated by Pultrusion method with carbon fiber, which has a guaranteed tensile capacity of 234kN and elastic modulus of 150kN/mm2. From this investigation, it is evident that the flexural capacity of RC beams strengthened with tensioned CFRP plate increased, when compared with that of the reference beam without strengthening, no matter how the beam was deteriorated. This was further enhanced by installing the intermediate anchoring device in the shear span of the beam, because the peeling of the plate was delayed. It is also evident that the fatigue life of RC beams was increased by using tensioned CRRP plates.
