Experimental investigation on behaviour of hybrid fibre reinforced concrete column under axial loading

Ductility and energy absorption capacity are the main requirement of earth quake resistant structures. Concrete can be modified to perform in a more ductile form by the addition of randomly distributed discrete fibres in the concrete matrix. This study presents the structural behaviour of hybrid fibre reinforced concrete column made with the combination of steel and glass fibres under axial loading. The various parameters like load carrying capacity, ductility, energy absorption capacity and toughness index of hybrid fibre reinforced concrete column are compared with that of conventional reinforced concrete column and steel fibre reinforced concrete column. It has been observed from the experimental investigation that the behaviour of HFRC column is relatively better than conventional reinforced concrete column and steel fibre reinforced concrete column in all respects.
