Abstract

The use of High Performance Fibre Reinforced Cementitious Composite (FRCC) systems as a repair/strengthening of RC columns is an innovative technique for increasing their capacity and preventing brittle failures when a seismic event occurs. This study presents and discusses the results of an experimental program carried out on nine scaled RC columns under compressive axial load. In particular, six columns were strengthened with FRCC, two columns were confined with uniaxial carbon fibres (CFRP) and one unstrengthened coloumn was used as control specimen. The strengthening with FRCC consisted of the total replacing of the existing concrete cover with a thin layer of FRCC for the entire length of the specimen. The behaviour of columns strengthened with FRCC is compared with the two columns confined by using CFRP. The effectiveness of the FRCC repair/strengthening technique was investigated by means of comparisons with the response of the control specimen and columns confined with CFRP. The specimens’ response has been analysed in terms of failure modes and strength/deformation capacity.
