Evaluation of Bond Strength of a Fire-Damaged Reinforced Concrete Structure

화재로 인해 손상 받은 철근콘크리트 구조물의 콘크리트 부착강도 평가

Evaluation of bond strength of a fire-damaged reinforced concrete structure for determining whether to reuse, reinforced, or abandon the structure is very important. Recently, calculating method for changes in bond strength of rebars is proposed by C. Chiang. The equation is relating the ratio of residual bond strength, R, to temperature, T, and exposure time, t. This study presented and verified a general process for evaluating damage to bond strength of RC structure arising from high temperature.
