用外部粘结纤维增强聚合物(FRP)板,来加固和修复原有的钢筋混凝土结构,最近已引起土木工程界的极大关注。许多试验也已证明了纤维增强聚合物的优点,但是在寒冷地区的性能尚需要更多的数据来验证。本文介绍了国外科技界在这方面的一些研究成果。
The use of externally bonded fiber reinforced polymer (FRP) panels to reinforce and repair existing reinforced concrete structures has drawn great interest recently in the civil engineering community. Many tests have also proven the benefits of fiber-reinforced polymers, but more data are needed to verify the performance in cold regions. This article introduces some foreign scientific and technological achievements in this area.
