火灾后混凝土损伤具有随机性和非线性的特点,对其进行评估和加固修复具有极大的挑战性,关系重大且难度甚高,是近年来研究的热点。综合分析近年来火灾后钢筋混凝土结构损伤检测与加固修复方法的若干研究成果,包括各种火灾温度的检测和评定方法以及各种火灾后混凝土的材料强度与损伤深度检测方法等。在论述研究成果的同时,对若干成果的应用状况做了简要的评述。对火灾后钢筋混凝土结构损伤检测的未来发展趋势做出了一些预测和展望。
The damage of concrete after fire is characterized by randomness and non-linearity. It is very challenging and challenging to evaluate and reinforce concrete. It is a hot topic in recent years. This paper comprehensively analyzes some research results of damage detection and reinforcement and repair methods of reinforced concrete structures after fire in recent years, including the detection and assessment methods of various fire temperatures, as well as the testing of material strength and depth of damage of concrete after various fires. While discussing the research results, this article briefly reviews the application of some achievements. After the fire damage detection of reinforced concrete structures to make the future trend of development made some forecasts and prospects.
