A study on Heat transfer analysis and Experiment of Reinforced concrete columns using 500°C Isotherm method

摘要

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.
