FRP加固钢筋混凝土墩柱抗震性能研究综述

摘要

回顾并总结了纤维增强复合材料(FRP)片材和织物抗震加固钢筋混凝土(RC)结构的研究现状,介绍了FRP的加固方式,包括粘贴形式和锚固方法；对影响FRP抗震加固效果的原柱条件、加固参数和受力条件的试验研究现状进行了归纳,探讨了FRP加固墩柱的破坏模式及FRP加固结构的抗震性能理论研究进展.针对现有研究成果,提出了一些FRP加固结构抗震性能研究的建议和意见,为其后续研究提供了参考.%The state-of-the-art research on reinforced concrete (RC) structures seismicstrengthened with fiber reinforced polymer (FRP) laminates or cloth was summarized and reviewed.The strengthening methods including bonding configuration and anchorage method were introduced.The main parameters affecting seismic performance of strengthened RC structures strengthened with FRP,including building structures condition,strengthened parameters and loaded state,were summarized.Meanwhile,failure modes of RC columns strengthened with FRP and theory research of seismic performance of RC structures strengthened with FRP were discussed.In view of the obtained research results,some suggestions and opinions for seismic performance of structures strengthened with FRP were proposed,which provided beneficial references for the future investigation.
