摘要
现代建筑中多层钢筋混凝土框架厂房使用越来越普遍,火灾在部分工程中频频发生,严重影响到结构材料性能。灾后结构构件的承载力和可靠性大幅削弱,进而引起结构安全性及可靠性大大降低。因此灾后的结构检测鉴定及加固方法受到了工程人员和设计人员的越来越多关注。本文结合工程实例,通过火灾后的检测鉴定和加固设计方法两个方面进行了讨论,可为混凝土结构火灾加固检测鉴定、加固设计及施工提供借鉴。
With the using of reinforced concrete frame building as factories being more and more common currently, fires occur frequently in some projects which seriously affect the structural material properties. Bearing capacity and reliability of the structural elements are substantially weakened by fire, thereby causing structural safety and reliability greatly reduced. Therefore, appraisal and reinforcement structure method after the fire take the engineering and design staff of more and more attention. In this paper, combined with a practical engineer, it is discussed from two aspects of detection and appraisal methods and reinforcement design after fire. It can provide reference for design, detection appraisal and construction for concrete structure after fire.
