摘要
本文结合我国现行钢结构设计规范，提出了一套钢梁抗火计算和设计的实用方法。本文首先给出了火灾下钢构件内部升温的计算公式，然后导出了高温下钢梁的承载力验算公式和钢梁临界温度的计算方法，最后通过计算示例说明了本文方法的实际应用．
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.
