Abstract / Description of output

Extensive research has shown that fibre reinforced polymer (FRP) wraps are very effective for strengthening concrete columns for increased axial and flexural load and deformability, and this technique is now widely used around the world. The study reported in this paper extends the FRP confinement technique to strengthening fire damaged concrete columns. An experimental program was undertaken to study the compressive strength and stress-strain behaviour of both unconfined and FRP confined concrete cylinders after being heated to elevated temperatures for up to four hours and cooled to room temperature. The results show that FRP confinement is highly effective for enhancing the load carrying capacity of even severely fire damaged concrete columns.
