Analysis and Design of Guyed Tower using ANSYS

Abstract

A Guyed tower structure is a tall and thin vertical formation that depends on guy wires for its stability. The mast of the tower itself has its compressive strength to support own weight, but it does not has the shear strength to stand upright, and because of which it requires guy wires to resist the lateral forces such as wind, earthquake loads etc., to keep it upright. Guyed towers are frequently used to mount radio antennas, telecommunication satellite and in case of emergency situations as well. Currently, the simple design methods are available for greater heights in the respective design codes. Hence, the objective of the this study is to thoroughly compare and design towers using different codal provisions and under various combination of design load using ANSYS software. Our approach will be to use different steel sections for the upper and lower parts of the Guyed tower which will serve two purposes. Firstly, Making the structure lighter so that it can withstand the forces and does not collapse under its own weight and secondly, making it cost effective. The main advantage of guyed tower is its height which helps to cover a much larger area for communication purposes as compared to the large number of towers working in that particular area. Also if a single guyed tower is used it will automatically reduce the overall cost of installation as well as future maintenance cost is significantly reduced. The final results are provided along with the cost estimation of installation of single guyed tower instead of providing several towers for the same purpose.
