“…Transient Heat Transfer Analysis is used to correspond analysis time to actual mechanical time. [3] A merge function is applied for boundary surfaces between different materials, and modeling in regards to RC columns using this method is shown as in Figure 3. In the finite element heat transfer analysis, consideration is taken to basic heat transfer mechanism, namely conduction, convection, radiation.…”

This study aims to assess heat transfer analysis of RC columns and unstressed test by applying 500°C isotherm method, which is the strength deterioration estimation method of Eurocode, inorder to use it as basic data for fire engineering design. According to the heat transfer analysis and fire resistance experiment, it was decided an appropriate axial ratio of RC columns that have cross sections of 300 and 350 can be anticipated as 0.49 and 0.59.
