摘要: 为更全面地反映火灾对工业厂房可靠性的影响,确保火灾后结构安全性评级的准确性,结合我国火灾后工业厂房可靠性评级的特点,加入抗火性这一特殊指标,将耐火等级、火灾裂缝和变形3个因素作为抗火性的评级指标,并确定抗火性等级划分标准。建立基于Vague集相似度量理论的、考虑抗火性的火灾后工业厂房结构可靠性综合评级模型。将模型应用于5个工程实例。结果表明,评级结果与规范评级法的结果一致;与未考虑抗火性的规范评级法相比,量化后的评级指标不仅评级过程清晰,而且能有效避免人为因素导致评级结果出现的误差。

Abstract: In order to more fully reflect the influence of fire on industrial workshop reliability, and ensure the accuracy of rating of structure safety after fire ,the existing reliability rating practice was examined ,and the fire resistance was introduced as a new rating indicator, including the refractory grade, fire crack and deformation .Fire resistance rating classification standard was established. A structural reliability comprehensive rating model was bulit for industrial buildings after fire,which considers the fire resistance and is based on Vague set similarity measurement theory. The model was applied to five engineering examples. The results show that the rating results obtained by using the model agree with the results obtained by using the standard rating methods,and that using the model can avoid errors resulted in by human factors.

Key words: fire, industrial building, fire resistance, Vague theory, structure security rating
