An Experimental Comparison Study on the Strength and Earthquake-resistant Capacity of Reinforced Concrete Columns Retrofitted with Fiber-Steel Composite Plate

복합플레이트로 보강된 RC 기둥의 내진성능에 대한 연구

The purpose of this study is to investigate the strength and ductility improvement of columns retrofitted with Fiber-Steel Composite Plate, compared with Steel Plate, and Carbon Fiber Sheet. Test specimens strengthened with 3 different materials--- carbon fiber sheet, steel plate and fiber-steel composite plate --- were tested under cyclic lateral force and a constant axial load equal to $20\%$ of the column's axial load capacity. The hypothetical equivalent value of the strengthening among three materials is introduced to evaluate.
