Numerical analysis of structures with a GFRP application in a transmission line tower

Resumo

This work aims to investigate through numerical simulations the mechanical behavior of the glass fiber
reinforced polymeric (GFRP) line post structures. It is presented a numerical validation of the mechanical
properties of the composite material, in order to ensure the representativeness of the model. Additionally, in order
to understand the impact of parameters change, such as fibers orientation, layer thickness, and resin type in the
structure model, the structure mechanical response curves is evaluated. Therefore, a parametric analysis is made
to provide an understanding on the structure response characteristics such as load versus displacement, stress
versus deformation, buckling modes, as well as the cause and effect relationship in the results obtained. The
orientation of the fibers showed to be the most important parameter on the mechanical behavior of the structure,
as well as the number of layers, a factor observed as being one of the most relevant in the verifications of the
buckling modes.
