| Abstract: | A practical approach, based on the up-to-date Chinese Code for the Design of Steel Structures, is proposed in this paper for fire-resistant calculation and design of steel beams. The formula for calculating the internal temperatures of steel members in fire situation is fistly presented. Theh, the equation and prooess for estimating the loadcarrying capacity of steel beams in high temperatures and critital temperatures of steel beams are derind. Finally, example calculations are conducted to show how to use the present approach in the engineering practice. |
