A novel retrofit technique for strengthening steel columns using FRP

Fiber reinforced polymers (FRP) are commonly used to repair and/or retrofit concrete and masonry structures. However, compared to concrete and masonry structures the use of FRP for retrofitting steel structures, particularly members such as steel columns and connections, has been limited. This paper investigates a novel retrofit technique to strengthen l-shaped steel columns, through a set of experimental tests on short columns. The proposed …
