| الوصف: | The use of the tapered glass fiber-reinforced polymer (GFRP) poles are well recognized as an alternative for traditional materials such as wood, steel, and concrete, in overhead power lines and distribution aerial networks. The current research work aims to assess the general behaviors of lightweight GFRP poles structures. A nonlinear finite element (FE) analysis is carried out to address the nonlinear behavior of tapered GFRP poles under lateral loads. The numerical results of the program are verified with the experimental results conducted on full-scale GFRP poles. The GFRP poles are fabricated using the filament winding technique; E-glass fiber and Epoxy resin are utilized for manufacturing these poles. There is very satisfactory agreement between the numerical results and the experimental results in terms of load-deflection relationship and ultimate load carrying capacity. The FE model was used to detect the performance of GFRP poles having service openings (holes). Several FE simulations with different combinations of parameters, such as fiber orientation, number of layers and thickness of layers, were employed. Evaluation of the deflection and bending strength characteristics of GFRP Poles (20, 33, 35 and 40 ft height) are presented. Optimum new designs for three zones along the height of the GFRP poles are proposed, under equivalent wind load. The ultimate load carrying capacity and flexural stiffness are improved with a significant saving in the weight by utilizing this design. |
