摘要
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 characteristics of randomness and structures. It is a challenging task and tough mission engineering. Many ways of the diagnosis and repair for nonlinearity is possessed by fire damaged concrete to diagnose and repair the structural damage in civil concrete structures were discussed in details. Therefore an overview was given on several key issues and related research progress made in detection and repair for fire damaged concrete structures. The research topics include the detection methods and the repair technology. The detection methods contain a variety of fire detection and evaluation and a variety of fire damaged concrete strength and the damaged depth. In addition, research achievements on the mentioned topics were discussed and several examples were included as the case studies. Finally, recommendations were proposed for the future development of detection and repair for fire damaged concrete structures.
