doi:10.3969/j.issn.1674-0696.2011.02.07

Abstract

Abstract: Basic thoughts and contents of risk based fire resistance countermeasures for bridges were discussed, including the relations between fire resistance level and fire resistance perform ance of bridges, the determination of fire resistance grade for bridges and the objective of fire resistance performance; fire resistance methods for bridges were proposed which could be achieved by varying grade parameters.Anactual engineering was used to illustrate the applicability of the proposed method.

Key words: bridge engineering, fire resistance countermeasures, risk assessment, decision making

摘要： 阐述了基于风险的桥梁防火措施的基本思想与基本内容,包括桥梁防火水准和防火性能之间的关系、桥梁防火等级划分以及防火性能目标；提出了考虑风险的桥梁防火措施选择方法,这只需简单改变等级参数即可；通过一个算例来说明该方法的应用过程。
