Abstract
철근콘크리트 구조물은 사용기간 안에 과다 하중, 반복하중 등 여러 가지 요인으로 인하여 손상을 입게 되는데, 철근 부식된 철근콘크리트 구조물에 대한 정적거동에 관한 실험은 활발하게 실시되고 있으나, 아직까지 동적거동 파악을 위한 실험 및 해석은 미흡한 실정이다. 이에 피로 실험을 통하여 철근이 부식된 철근콘크리트 구조부재의 거동을 검토하는데 목적이다. To study the influence of reinforcing bar corrosion on the fatigue properties of reinforced concrete structures, beams reinforced with four different corrosion grades of reinforcing bars were tested. These corrosion grades have been achieved by impressing direct current for increasing periods on the reinforcing bar embedded in beam specimen located in water ; the current is so arranged that the reinforcing bar serves as the anode while a copper plate is located in the water to act as cathode. deflection, strain, and crack width increased in reinforced concrete beams with corroding reinforcement at maximum load approximately in proportion to log N.
