| 摘 要： | 随着CFRP在混凝土结构加固中的广泛应用,其防火问题引起关注。但是目前关于高温下CFRP加固构件的防火性能研究成果相对较少。以当前国内外相关研究成果为基础,用有限元程序对加固构件进行高温下的传热分析和力学分析,运用有限元程序在计算机上再现了防火试验的全过程。研究荷载比、CFRP加固量、防火材料厚度以及混凝土保护层厚度等因素对采用硅酸钙防火板保护的CFRP加固梁耐火极限的影响规律,并得到了不同工况下的CFRP加固钢筋混凝土梁的耐火极限,为CFRP加固混凝土梁的防火设计提供了依据。

| Abstract: | With the popularity of structure repairing and strengthening by bonding CFRP sheets,fire endurance problems of CFRP strengthened structures have also attracted much attention.But the researches on the fire resistance of CFRP strengthened structures are still scarce relatively for the moment.Based on the latest researches summarized,and by mean of software,thermal and mechanical analyses are carried out by numerical analysis in this paper,and the whole fire procedure is repeated on computer.And in this way,m... |
