摘要
CECS200-2006《建筑钢结构防火技术规范》采取等效作用力方法计算火灾下的结构内力,并给出了受火构件温度内力的计算公式。本文就规范中结构抗火计算方法和有限元数值计算方法,按不同结构抗火计算方法对算例进行对比计算研究。计算结果表明,规范中所给内力公式计算的结果较保守。
An equal method to calculate the internal force of the structure under fire condition is provided in the technical code for fire safety of steel structure in buildings （CECS200 - 2006）. The formulas are provided to get the inner force of the elements under high temperatures. The comparison analysis is provided between the ways in code and the other ways of finite dement analysis. According to calculation methods of the code and other ways of finite element analysis, some numerical examples are given. The numerical examples show that the equal method in the code is stricter than other finite element analysis ways.
