Flexural Behavior of FRP Composite Pole Structures: Nonlinear Finite Element Analysis

摘要

This paper presents a finite element modeling of the nonlinear behaviour of laterally loaded, fullscale tapered fibre reinforced polymer (FRP) pole structures. Parameters considered were the fibreorientations of longitudinal and circumferential layers, number of circumferential layers and the effect ofreplacing glass fibre by carbon fibre on the FRP pole behaviours. The GFRP poles are fabricated usingfilament winding technique; E-glass fibre and Epoxy resin are utilized for manufacturing these poles. Theresult to data indicated a good agreement between the results of the finite element analysis and theexperimental data. The results indicate that the flexural behaviour is highly dependent on the fibreorientation. The study demonstrate the benefits of using circumferential layers, and showed that a higherstrength can be achieved by providing outer and inner circumferential layers with longitudinal layers. It isfound that replacing carbon fibre by glass fibre of the FRP poles a good improvement achieved. The totalload capacity of the FRP poles and the stiffness are increased with increasing the percentage of carbonfibres.
