| Abstract: | Heat transfer models of a compartment fire have been established in this paper,a combination method of finite element and finite-difference was used to analyze the temperature distribution in steel reinforced concrete columns,and based on this procedure,a corresponding program was composed.The effectiveness and reliability of the approach are validated by the good agreement between the theoretical results and the experimental data at elevated temperature. |
