Study of strength and stability of a composite transmission tower Available to Purchase

This research study reports a finite-element (FE) analysis undertaken to determine the strength and stability of a transmission tower constructed with a carbon-fibre-reinforced epoxy composite under different loading conditions. The loading conditions such as wind, weight of wires and self-weight of structures were calculated manually and applied in the FE model. Different loading conditions including the broken wire condition (BWC) were innovatively considered in this paper. The results showed that at the transmission tower, the components near to the base of the structure had much less  longitudinal stress. At different loading conditions, including BWC, the composite material was found to be competent. An innovative design approach incorporating stability analysis was found to be appropriate for determining the stability and structural safety of the tower.
