Structural Optimization of Microwave Antenna Tower Subjected to Wind Load
The microwave antenna towers are important in the telecom industry as they are used to broadcast microwave transmission from one location to another. These open-latticed steel towers are highly indeterminate structure. In this paper, a 50 m microwave antenna tower mounted with a hollow hemispherical dome of 2 m diameter is considered. It is subjected to a multiple combination of wind, dead loads, and the self-weight of microwave antenna. The tower is designed optimally for least weight. It is having a base width of 6 m and is located in Bhubaneswar City having a basic wind speed of 50 m/s. The various sections chosen are angle, pipe, and tube section with tower having X-type bracing. Weight is considered as an objective parameter which is function of independent variables (base width, number of panel, and panel height ratio). The design wind force on each panel of the tower has been calculated according to IS 875 (Part 3): 1987. It has been seen that with angle section X bracing there is a reduction in weight of about 14% than the weight before optimization. The results show that angle sections are best suited for the design of microwave antenna as compared to pipe and tube sections.
