| 摘 要： | 火灾对建筑物的破坏主要是高温作用,要确定遭受火灾后钢筋混凝土构件的受损伤程度必须确定构件的受火温度。该文介绍了火灾后混凝土结构的检测,采用了岩相分析等方法准确地判定受火温度,并通过多种手段结合对结构受火后混凝土和钢筋的强度进行推定,评定结构受损程度。

| Abstract: | The damage from a fire to the structure is mainly caused by the fire temperature.To conclude the degree of damage,it is necessary to estimate the temperature first.This paper describes the detection of a firedamaged concrete structure.The lithofacies analysis method is adopted to determine the site temperature.To get the strength of concrete and steel bars after fire,several methods are used,and then the degree of damage is evaluated. |
