The behaviour of CFT columns exposed to fire is dependent on the thermal and mechanical properties of CFT materials. In this research, the Korean test's thermal properties model of the CFT materials(steel and concrete) is compared with the four model(Eurocode model, AIJ model, T.T. Lie model, J. Yin model) of the outside the country to estimate the thermal properties of the Korea test's model. Using the thermal properties, the numerical analysis was performed to estimate the fire resistance of the CFT structures. We evaluated the actual effect by the thermal and mechanical characteristics of the materials. Through this research, the temperature calculated from test model was overestimated than other models. It is because the thermal diffusivity of domestic concrete test model is the highest. Also, test model was suddenly collapse without sufficient axial deformation. It is because the thermal diffusivity of test model is higher than the other models. And it is because stress-strain curves decreased suddenly after yielding |
