This study aimed at investigating the seismic performance of hollow FRP piles compared to traditional piles in fine sand and soft clay deposits using shaking table tests. A laminar shear box with a dimension of 1.0 m × 1.0 m and a depth of 1.0 m was employed to contain the soil medium and allow the soil to respond in the same fashion as the free field. Two types of composite group piles (2×2) made of Carbon Fibre-Reinforced Polymer (CFRP) and Glass Fibre-Reinforced Polymer (GFRP) along with a series of Aluminium piles were manufactured and embedded as frictional and end-bearing piles within the soil. Several monitoring instruments were used to observe the soil-pile response under variety of ground motions adopted from the 2010 Val-des-Bois Earthquake in Canada and the 1995 Kobe Earthquake.Seismic response of the foundation was strongly dependent on the stiffness provided by the soil, which was a function of the degree of softening and intensity of shaking.
