Corner effects in CFRP-wrapped square columns Available to Purchase

An experimental investigation of the corner sharpness effect in square columns with carbon fibre-reinforced polymer (CFRP) wraps is presented using traditional compressive testing of short square columns as well as an innovative set-up that allows testing directly for the CFRP strength when wrapped around the corner of a flat slab. Both types of test confirmed the observation that the confinement efficiency decreases as the corner sharpness increases, owing to stress concentrations that cause localised failure of the CFRP.
