| Abstract: | The temperature of joints of a certain variable cross-section portal rigid frame under local fire was simulated using finite element method. The corresponding contour maps and laws of the temperature field were obtained and compared with testing data. As a result, an effective finite element method to steel structure temperature under local fire was set up. |
