| Abstract: | Finite element method is used to analyse the temperature field of square and round concrete filled steel tubes with different cross section area, thickness of fire protective layer,ignoring the fact that when material's thermotechnical parameters changes with temperature,the temperature field of a component will be affected when on fire.A simple and straight forward method of showing the character of temperature field and relevant parameters is also given in this paper.The result through calculation matches those from experiments perfectly. |
