Repair of fire damaged circular reinforced concrete columns with FRP composites

Behavior of Fire Exposed Concrete-Filled Double Skin Steel Tubular (CFDST) Columns under Concentric Axial Loads

“…Therefore, it can still carry load until the ends of fire course. Secant stiffness of CFDST columns can be calculated by dividing ultimate load with displacement at ultimate load [9]. As can be seen in Table 2 and Fig.…”

Experimental and numerical study of the behaviour of heat-damaged RC circular columns confined with CFRP fabric

“…No unloaded specimens were tested as there is sufficient data in the literature to give the residual behaviour of concrete. In terms of the repair of post-heated RC circular concrete columns, only one study has been reported by Yaqub and Bailey [34] in the literature. However, this investigation was limited to unstressed columns and furnace temperature exposure up to 500°C only.…”

Fibre Reinforced Cementitious Matrix confined concrete elements

“…A decade's worth of experimental studies and theoretical analysis as well as multiple engineering applications have established the FRP technology as a proven reinforcement for compressed concrete elements [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Concurrently with the experimental studies, the r-e model of FRP and FRCM confined concrete elements is being developed [26][27][28][29].…”
