내화피복 강재의 내화성능 평가 예측에 관한 연구

With a rapid development of economy, more high-rise buildings are being constructed in large cities than before. As a result steel members such as beams, columns make a great role of the building construction, and the need of them to be protected to have enough fire resistance is in-creasing . But conducting a real fire test to all the members is almost impossible. So prior to do conduct a real fire test of the protected steel members, evaluating the fire resistant rating of them by means of their specific properties might be economical things. This study is aimed to introduce the fire resistant rating of protected steel members without a real fire test through the related studies and data.
