| Abstract: | Based on the temperature distribution of CFST and the stress-strain relations of steel,bars and core concrete of bar-reinforced concrete filled steel tubes,theoretical model for the analysis of fire resistance of bar-reinforced concrete filled steel tubes with circular or square has been put forward in the paper.The model has been verified by experimental results and good agreement has been reached.The method presented in this paper may be referenced for the practical design and code writing. |
