“…Composite materials have also been used to a certain extent in the field of power transmission towers. Traditional cement poles or metal transmission towers generally have problems such as high weight and short service life [76,77]. The use of composite materials to replace traditional transmission towers can effectively improve the level of lightning protection, and anti-fouling ability, and reduce line operation and maintenance costs.…”

“…They also performed a transient dynamic analysis of a GFRP pole [ 17 ]. Urgessa and Mohamadi [ 18 ] conducted further studies on such poles using ABAQUS software. This study concluded that the maximum stress in the FRP composite column increases with fibre orientation up to 45° from the axial direction and then decreases when increasing the fibre orientation to 60°.…”

Utility poles made of glass fibre-reinforced polymer (GFRP) are becoming increasingly common in European countries. Therefore, it is necessary to accurately examine their structural properties to ensure the integrity and safety of the poles. The purpose of this article is to compare the bending resistance of GFRP composite lighting columns obtained using European standard procedures with full-scale experimental tests. Several composite lighting columns were tested as part of the research study, and coupon tests were performed to assess the material properties required to calculate their bending resistance according to European Standard (EN) 40-3-3. The results obtained differed significantly. Furthermore, it was observed that the current standard rules for obtaining the resistance of GFRP poles based on the limit state method show a higher load capacity of the column in comparison to the capacity obtained from the tests.

“…Urgessa and Mohamadi [ 23 ] also numerically analyzed FRP poles using a finite element method algorithm. In their study, FEM parametric analyses were presented to ascertain the effects of the geometric properties, fiber orientation, number of layers, and lamina thickness on tapered FRP poles As a result of the tests, it was found that the maximum stresses in the FRP composite pole increased with the increase in fiber orientation angle to 45° (relative to the axial direction), and then decreased with a further increase in fiber orientation angle to 60°.…”

Glass fiber-reinforced polymer (GFRP) utility poles are becoming more widespread in European countries. To ensure the integrity and safety of poles, it is necessary to carefully examine their structural features. The purpose of this paper is to present the numerical model of a column made with the engineering simulation software ANSYS and to compare the experimentally determined values of the stresses that lead to column failure close to the inspection hole with the results obtained using the numerical model. The critical buckling and failure loads for GFRP poles, as well as the associated modes of failure, were correctly predicted by the finite element method used in this study. Failure occurred in the middle of the inspection hole’s longer edge at a stress level of 220–250 MPa. A comparison of the stress using the ANSYS simulation software that led to the destruction of the column with those measured experimentally using strain gauges revealed a good agreement between their values.
