Reinforced concrete structures are often required repair and strengthening because of various external factors. Recently, fiber reinforced polymer or plastic (FRP) in the form of sheet or plate is often used in repair and strengthening RC structures. Many of previous researches have conducted theoretical examinations and experiments on repair and strengthening with FRP and supplied materials necessary in construction sites, but few of them are about the effects of strengthening quantities on the strengthening effect. Thus, this study purposed to analyze through experiment, the flexural strengthening effect of section increment method using carbon fiber reinforced polymer(CFRP) strengthening RC structures.
