摘要
提出了钢筋混凝土结构的过火特点,分析了火灾时混凝土和钢筋的损伤程度、握裹力的变化、持续时间及灭火方式的影响;对桥梁各部件的过火损伤进行了探讨,并通过工程实例分析了火灾病害对桥梁结构造成的危害,为灾后检查提供参考。
The fire characteristics of reinforced concrete structures are proposed and the influence of damage degree of concrete, the steel bar on the change duration of holding force, and the way of extinguishing fire are analyzed thereafter. The fire damage of bridge parts is discussed to analyze the damage of fire hazard to bridge structure through engineering examples, which provides a reference for post-disaster inspection.
