열 하중을 고려한 합성기둥의 내화성능설계 도표 제안

Most of the studies carried out in the domestic fire-resistant structure is carried out in furnace. For the experiment with a heating method is constrained due to the absence size and equipment performance limits. Some overseas, and promote design conveniences to offer a fire resistance design style without having to experimental verification. Fire resistance structural design variables included in the function expression has been noted in a reasonable way to design a comprehensive way. In this paper, fire-resistant design fire resistance design equations propose a graph of composite columns. Cross-sectional size by the proposed design graph, the length, the fire resistance can be predicted, regardless of the material strength.
