• Abstract:
  The overall goal of this project is the experimental evaluation and design of unfilled and concrete-filled FRP ; composite piles for load-bearing in bridges. This report covers Task 3, FRP Composite Pile Flexural Testing. ; Hollow and concrete filled fiber reinforced polymer (FRP) piles were tested in four point bending to examine ; degradation in stiffness, ultimate strength, and loss of concrete‐FRP composite action due to pile driving and cyclic ; loading. Testing showed a high level of variability in the ultimate strength of the piles, but all driven and load-cycled ; samples broke within the upper and lower bounds of the control piles. This series of tests showed no degradation in ; stiffness during static tests in the piles due to driving or cyclic loading. However, driving and cyclic loading appear ; to affect composite action between the FRP shell and concrete
