Carbon FRP 보강 RC기둥의 전단성능 평가 = Shear Capacity Evaluation of RC Columns Strengthened by Carbon FRP

다국어 초록 (Multilingual Abstract)

When the RC frame structures subjected to the seismic load, brittle shear failure of vertical members may induce brittle collapse of systems. These failure mechanism is not desirable and will be make a whole structure collapse. So shear strengthening method to avoid this failure mechanism is needed. Recently, strengthening method using carbon FRP sheet is used widely which have high elastic and high strength characteristics. In this study, RC columns which is strengthened by carbon fiber sheet in the form of tape or whole sheet were tested under the cyclic load. The parameter of this test is the strengthening amount. As the strengthening amount increases, strength, ductility and energy capacity also increase. The failure mechanism was changed to bond-splitting shape from brittle failure shape. By using the proposed shear strength estimation methods, the shear strength of carbon FRP reinforced RC columns could be approximately estimate.
