Abstract
— In recent years, FRP composites, which are made of reinforcing fibers and a thermosetting resin, have been widely used as advanced construction materials. The tapered FRP poles are currently considered attractive in the application of the light poles and electrical transmission tower element. A finite element (FE) program was used to perform a nonlinear numerical analysis to model the static flexural behavior of CFRP poles. A parametric study was carried out to study the effect of replacing glass fiber (GFRP) by carbon fiber (CFRP) on the FRP pole behaviors. The ultimate capacity, top deflection and stiffness increase are presented. The study demonstrates that replacing carbon fiber by glass fiber of the FRP poles a good improvement achieved. The total load capacity of the FRP poles and the stiffness increased with increasing the percentage of carbon fiber.
