Probabilistic assessment of FRP-confined reinforced concrete columns

This paper presents a reliability study on reinforced concrete (RC) columns retrofitted by Fibre Reinforced Polymers (FRP) confinement. First, variability of the compressive resistance of FRP-confined RC columns considering uncertainty in the model error, material properties, section dimensions, FRP strain efficiency factor and minimum load eccentricity as well as any existing correlation among random variables was studied. Then, reliability of...
