This study develops numerical model of mega composite columns in fire and investigates the residual areas below 500℃ after 3 hours. In order to perform heat transfer analysis, thermal properties of steels and concrete were adopted from Eurocodes. In addition to, the temperature distributions of composite columns with respect to fire tests were compared with numerical analysis results. As a result, the residual areas below 500℃ of mega composite columns were evaluated.
