The most fast, effective and simple method is external bonding. Traditionally steel plates bonding was done in Europe, USA and Japan. But there is requirement to find other method beside steel plates, because of corrosion and weaken heat-resisting property of steel. For this reason FRP(fiber reinforced polymer) composites have been used since 1980’s FRP composite materials has high resistance to corrosion, tensile strength and high fatigue strength rather than steel plate. Therefore this way to strength is known as suitable method. In addition, according to different reinforcing pattern, quite a few reinforced concrete structures using FRP reinforcement for reinforcing study show various result. Therefore, our purpose in this study is that analysis reinforcement effect according to various reinforcement patterns.
