Load Carrying Capacity of Hybrid FRP-Concrete Composite Pile

Abstract:

In the study, in order to enhance the durability and constructability of the pile foundation, hybrid FRP-concrete composite pile is developed and its applicability considering construction is discussed. Existing FRP-concrete composite pile is consisted of concrete pile and filament winding FRP wound outside of the pile. To improve the axial and transverse load carrying capacities longitudinal reinforcement is also needed additionally, and hence a new type hybrid FRP-concrete composite pile (HCFFT) is suggested. A new type HCFFT which is composed of pultruded FRP, filament winding FRP, and concrete filled inside of the FRP tube is proposed to improve compressive strength as well as flexural strength of the HCFFT pile. The load carrying capacity of proposed HCFFT pile is evaluated and discussed based on the result of experimental and theoretical investigations.
