EXPERIMENTAL STUDY ON THE MECHANICAL PERFORMANCE OF FRP-CONFINED SOFTWOOD TIMBER POLES

This paper presents a study of using fibre reinforced polymer(FRP)composites as confinement system onto softwood timber poles for potential application as electrical distribution poles.The proposed FRP confinement method was a wet layup process using multiple layers of(Biaxial)90o/0o woven roving E-glass fibre sheets.A series of FRP confined timber pole specimens,with different confinement lengths ranging from 0%to 70%of the span length,were prepared and tested in threepoint bending to present two equivalent cantilevers.A timber/FRP composite section with full confinement length was also investigated.Results showed that the FRP confinement system provided a considerable improvement to the softwood poles in terms of the load carrying capacity and bending stiffness.Theoretical calculation was also conducted to estimate the bending stiffness showing good comparison to the experiments.
