建筑物遭受火灾后,必须对其结构性能进行检测,依据检测结果,确定合理的加固方案。为此本文分析了混凝土结构火灾后损坏的机理和破坏作用,介绍了钢筋混凝土结构火灾检测的一般方法以及受损构件加固的处理措施。 After a building is subjected to a fire, its structural performance must be tested, and based on the test results, a reasonable reinforcement plan should be established. Therefore, this paper analyzes the damage mechanism and destructive effect of concrete structure after fire, and introduces the general method of fire detection of reinforced concrete structure and the treatment measures to reinforce the damaged structure.
