고온을 받은 철근콘크리트 보 부재의 휨 거동에 관한 실험적 연구

The purpose of this study is to experimentally investigate the flexural behaviors of reinforced concrete beam members after exposed at high temperature. In order to investigate the flexural behaviors, we have tested fifteen reinforced concrete beam members with various reinforcement ratios (ρ_(max), 0.5ρ_(max), ρ_(min)) and heating conditions (non heating, 400℃-2hr/4hr and 800℃-2hr/4hr). The results show that failure mode, load-displacement relationship, initial stiffness and moment-strain relationship are affected by the parameters.

The purpose of this study is to investigate the flexural behaviors of reinforced concrete beam members exposed to high temperature. In order to investigate on the flexural behaviors, we have tested fifteen reinforced concrete beam members with various reinforcement ratios(ρ_(max), 0.5ρ_(max), ρ_(min)) and temperature(400℃, 700℃) include load-bearing heating. The results show that failure mode, load-displacement relation, initial stiffness as loading conditions.
