Field Applications of Concrete-Filled FRP Tubes for Marine Piles

Abstract

The paper discusses an innovative composite pile composed of concrete filled fiber reinforced polymer (CFFT) circular tubes. Also describes is an experimental program that has been conducted over the past six years to study the structural performance of CFFT under axial compression, bending and combined loading in marine environment. Eight field applications of the composite pile are briefly described, along with test results of the experimental program and the design charts.
