Recently the requirements of the buildings built with structural steel were increased in terms of structural stabilities and fire resistance at severe fire conditions. To meet the building regulations of fire resistance, a fire design is needed. This is of a prescriptive method and a performance engineering based method. Recently a simple calculation method as one of performance based engineering method is very popular because of its ease for an application in building built with structural steel. But, in Korea the performance based engineering method is not allowed yet. Thus it is needed to make a guideline for the performance based engineering method. The purpose of this study is to establish the limit temperature derived from structural beams made with both a H-section and a H-section filled with concrete at the web and derived the limit temperatures from beams made with H-sections and found out that the limit temperatures from two kinds of specimens depended on the applied loads and the specimens filled with the concrete represented 3 hour fire resistance in the range of 80%, 60%, and 50% of the maximum load.

This study, to develop the technology of the fire resistance design of CFT structure based on fire resistance performance design, was suppose to use as basic data for performance design through a measure of temperature and deformation of the CFT specimen as parameter is the concrete compressive strength and load ratio. In accordance with KS F 2257-1 and 7, 24 MPa and 40 MPa and the load ratio of 0.9, 0.6 and 0.2 were imposed on a square column and as a result of evaluating in accordance with the fire resistance criteria, in case of 24 MPa, the fire resistance performance was improved by 73 minutes when the load ratio was reduced by 0.3. And when it comes to 40 MPa, the fire resistance was 31 minutes and 180 minutes when a load ratio was 0.6 and 0.2, respectively. As a result of evaluating fire resistant performance depending on variation of internal concrete strength, it proved that the higher the strength the lower the fire resistance.

최근 초고층구조물 및 대공간구조물등에 대한 소방법의 성능설계등이 법제화되어 시행될 예정으로 있으나 화재성상예측등에 대한 기초적인 연구등이 매우 부족한 실정이며 이에따라 성능설계를 실시하기 위한 기반여건이 매우 취약한 조건이다. 특히 강구조건축물의 경우 초고층구조물의 전형적인 구조형식으로서 성능설계에 대한 연구기반이 조속히 필요한 실정이다. 따라서 본고는 전보에 이어 화재하중등과 밀접한 관련이 있는 가연물조사등과 더불어 이에 대한 이웃 일본건축학회의 강구조건축에 대한 성능적 내화설계방법론중 하중편을 조사하여 향후 국내의 화재하중선정을 위한 기초자료로 사용될수 있도록 하였다.

급속한 산업의 발달과 기술의 향상으로 건물은 점점 고층화, 다양화되고 있지만 이러한 건물에서 화재 시 대응방안은 아직 미흡한 실정이다. 건물이 다양해짐에 따라, 그에 따른 건물의 화재거동 또한 건물 내의 가연물의 양, 종류 및 건물의 용도 등에 따라 다른 양상을 띠고 있기 때문에 화재에 영향을 미치는 여러 가지 요소들을 충분히 고려하여 건물의 내화성능을 충족하여야 한다. 따라서 본 연구는 화재로 인한 인명과 구조적 피해를 줄이고 보다 안전한 건축물을 설계하기 위하여 미국의 건축물 내화설계 절차에 관한 연구를 통하여 우리나라에 적합한 성능적 내화설계법을 도입하기 위한 기반자료를 도출한다.

This study, to evaluate the technology of the fire resistance design of Reinforced Concrete columns based on fire resistance performance design, was suppose to use as basic data for performance design through a measure of temperature and deformation using heat transfer analysis and Heat-load test of the Reinforced Concrete columns as parameter is the axial load ratio. In accordance with axial load without eccentricity, the load ratio of 0.30, 0.35, 0.40 and 0.47 were imposed on columns. As a result of this study, 0.40 or more of axial load ratio can be ensured that the fire resistance performance was considered satisfactory.

Concrete filled steel tubes(CFST) is considered as a column having better structural stability and better performance of fire resistance than that made with H-section and hollow section in itself. To get the fire resistance of the CFST, two kinds of concrete strength were used, 21 MPa, 40 MPa and 4 sorts of the applied loads were calculated and used to the specimens such as 3.5 m long, round and rectangular section. After various fire tests under 4 sorts of load ratios, the fire resistance of the CFST is not possible to get over 1 hour because of the rapid decrease of concrete strength. The below 50% of the applied load is recommended to obtain over 1 hour fire resistance of the CFST.

In the Building Act, performance-based fire safety design is being promoted for institutionalization. The behavior of the structure against fire conditions can be predicted by using the advanced numerical analysis method based on the FEM (Finite Element Method) to predict the entire structural behavior including the behavior of the structure, but there is a limit to expressing the fire properties of the space and predicting the fire properties It is difficult to determine the variables to be transmitted to the FEM (Finite Element Method) model from the fire simulation results using FDS (Fire Dynamics Simulator). Accordingly, the purpose of this study is to introduce the code user's manual for FDS and FEM unidirectional coupling analysis.
