摘　　要：火灾是最经常、最普遍地威胁人类生命财产安全和社会发展的主要灾害,而建筑火灾一般要占火灾总数的60%左右。就火灾而言,建筑物结构构件均会遭到不同程度、不同形式的损害,有的需要简单修复或拆掉重建,大多数经过有效加固便可以重新投入使用。本文针对钢筋混凝土结构在遭受火灾破坏后的不同破坏形态及不同破坏程度,以结构加固理论为基础,研究使用不同加固材料、工艺、加固方法及新型加固技术对该类建筑物进行加固处理,以确保其正常安全使用。The fire disaster, witch is the main threaten of the public safety and social development, is the most common disasters. Building fire disasters generally accounted for about 60% of the total. On fire disaster, the structural components of buildings are damaged in varying degrees and different forms. Some needs for a simple repair or reconstruction, the majority can be reinforced through effective reinforcement and can be used again. In this paper, aiming at the fire damage in the different failure modes and different degree of the reinforced concrete structure, based on the structural reinforcement theory, the study on different materials, techniques, reinforcement methods and new reinforcement technology for the damaged buildings is carried out to ensure the safe and normal use of them.
