Abstract: This paper provides test data on seismic behaviour of SFRC piles.
Four large-scale specimens are subjected to a combination of constant axial load and alternating cyclic flexure.
A similar number of specimens are subjected to alternating cyclic flexure without axial load.
Twin-cone fibres and new twin-crimped fibres in weight fraction between 40 kg/m(3) and 50 kg/m(3) are used.
The structural ductility and Energy Absorption Capability of SFRC piles are compared with that of reference RC piles.
These results and previous ones are used to assess the efficiency of fibres to reinforce concrete piles in seismically active regions.
When an axial load is applied,SFRC piles present behaviour similar to that of RC piles.
Fibres are then able to substitute for classical reinforcement.
Without axial load a simple cage of bars is needed at the head of the pile.
