| 요약1 |
본 연구에서는 고강도 콘크리트를 충전한 CFT기둥의 내화성능 개선을 위한 연구의 일환으로서 충전콘크리트의 강도, 강관의 폭-두께비, 섬유 혼입 및 내화피복 등의 요인에 따라 CFT시험체를 제작후 ISO-834 표준가열곡선에 준하여 내화실험을 실시함으로써, 화재시 CFT기둥의 거동해석 및 내화설계를 위한 기초적 데이터를 축적하고자 한다. |
| 요약2 |
Recently, it increases in use of CFT(Concrete filled steel tube, below CFT) that is an excellent internal force and deformation capacity because material and method are required to be diversification and High-Performance according to increase the super-high structure. But, CFT column lose bearing capacity under fire because steel tube is exposed to outside. As a result, structure is collapsed and then it cause much damage. In case of the Europe, Japan and America, they have studied the fire-resistance performance of CFT under fire for a long time. However, it would have hardly studied it in domestic because it is much difficulty about experiment machine and cost. So it is needed base on fire-resist performance of CFT under fire. Therefore, this study made seven CFT specimen that determine the four factor(which is strength of concrete, slenderness ratio of steel tube, fiber using, Fire Protective Coating etc.) and then CFT column was exposed to heating controlled as closely as possible the ISO-834 standard five curve during 3 hours. The purpose of this study is to suggest a basic data for structure regulation enactments of the fire-resist design of CFT. |
