각형CFT기둥 적용 건물에 대한 내화성능 평가

In foreign country, many studies about the fire resistance of concrete filled tube column and the structural design considering fire resistance have been progressed and, the performance design about members is standardized. In Korea, the structural design isn't considered to the performance of the members and the fire resistances of three times is only related to thickness of the protected materials. The purpose of this study is to be recognized on requirements of performance design considering fire resistance through investigation for the present condition and to propose the application methods of the performance design considering fire resistance for concrete filled tube columns in Korea.
