Confinement of FRP-jacketed reinforced concrete columns

摘要

There has been a worldwide increase in the use of fibre-reinforced polymer (FRP) composite materials for strengthening reinforced concrete structures in recent years. One important application of composite retrofitting technology is the use of FRP jackets to provide external confinement to reinforced concrete columns when the existing internal transverse reinforcement is inadequate or where there is a higher demand on the structure.
