| Abstract: | Considering the surface thermal resistance and nonlinear changing temperature distribution in protected steel member, this paper establishes differential equation on the basis of heat transfer principles to calculate the section temperature distribution. At the same time the article modifies the present calculating-models. It makes the accounted results match the experimental data better. |
