Abstract
This paper presents the characteristics of flexural behavior of RC beam strengthened with CFRP(Carbon Fiber Reinforced Polymer Plate). Experimental variables included the strengthening length, width, reinforcement ratio, end anchorage and preloading corresponding to 75 percent of ultimate capacity and the effects according to each experimental variables were analyzed. To study, a total 21 RC beams were constructed, tested and the response of the beams in terms of ultimate load, deflection, strain of CFRP, failure mode were examined.
