Abstract
Poles have an important purpose in the distribution of electrical energy. Other sectors such as the telephone and internet also use this means to bring their services to homes. Currently, the poles are made of wood, reinforced concrete, and steel. However, these materials are subject to problems such as rapid wood degradation, high weight and difficult positioning for reinforced concrete poles and corrosion in steel. Some alternatives are adopted to minimize these problems, such as wood treatment, optimization of concrete structures and protection of steel surfaces. Another alternative is to look for new types of materials to supply all pole requirements. Composite materials, such as glass fiber-reinforced polymer (GFRP), have great advantages because they are resistant, light and insulating. Monocoque and semi-monocoque structures, commonly used in aircraft fuselages, allow reduction in final mass, which combined with the use of composite materials generate even lighter structures (in the case of poles, up to seven times lighter). In this work, monocoque and semi-monocoque structures configurations were analyzed, using longitudinal stiffeners and transverse rings, in different combinations. The finite difference method was used for the calculation of the maximum deflection for the purpose of evaluatingthe stiffness adequately. Global and local buckling and failure were also evaluated. Abaqus™ commercial finite element software was used to obtain the results.
