An Experimental Study on the Behaviors of RC Beams Strengthened in Shear by Thin Steel Plate and Carbon Fiber Sheet

강박판 및 탄소섬유판으로 전단보강된 철근 콘크리트 보의 거동에 관한 실험적 연구

Since the mid of 1970's, the construction of infrastructure has been booming and accelerating to keep up with rapid economic growth. Fast achievement of most construction activities has caused unfavorable effects of civil petitions associated with damages and nuisances due to last hasty works. it is well known that the falling down of Sungsoo bridge and the collapse of Sampoong department and other structures have occurred because of the construction not conforming with the specification, and thereby incurred enormous loss of life and property.
