ABSTRACT
This work focuses on the structural analysis and response of an innovative design of a guyed mast for the telecom industry in which the power is supplied mainly by attaching a wind turbine on the top. For this purpose a numerical model based on the finite element method (FEM) was developed. The FEM model was validated with experiments conducted on one modular section of the mast, which was loaded in torsion. The model showed good agreement with the experimental results and revealed that failure in the modular section loaded in torsion is governed by non-linear buckling. The entire 57 m guyed mast structure was then modeled using the validated modeling procedure with applied loads corresponding to wind conditions resembling typical African landscape. The design wind loads were determined according to the Telecommunications Industry Association (TIA-22-G-1). Several structural design criteria were stipulated and the current design of the mast met all the requirements with a good margin of safety and hence making it a suitable product for the African market.
