Substructure elements are more influenced by earthquakes than superstructure elements. This is due to the lack of extensive investigation for the selected type of foundation. High rise building and towers usually require the use of piles or piled raft foundation to rigidly support building loads against earthquakes, in addition to, the severity of the environmental condition governs the materials selection of pile foundations. The usual traditional materials used in piling, such as concrete, steel and timber cannot withstand aggressive and marine environments as they suffer from strength degradation and highly effective rehabilitation cost. A relatively new trend in the piling industry is to use FRP as a substitute material. FRP material can be presented in several forms of piling, such as internal reinforcement in concrete piles, closed tubes and open tubes filled with concrete, etc. From the literature, very limited studies have investigated the use of FRP materials as pile under dynamic conditions. Thus, this paper studied the dynamic response of confined FRP pile behavior in sandy soil using the commercial finite element package, ABAQUS. The pile is made of FRP tubes filled with concrete. These FRP tubes had different orientation laminates and type of fiber (i.e. Glass: GFRP; Carbon: CFRP) with an outer diameter, 60 cm. The soil surrounding the pile is sandy soil. The influence of damping, FRP orientation, Young’s modulus of soil, FRP pile to soil interface and finally sand dilation angle were considered. The results show that damping, orientation of fibers and Young’s modulus of sand all have a significant influence on pile-displacement response under dynamic loading condition.
