ABSTRACT
In this study, an attempt is made that 220kV Transmission line tower is modeled using STADD Pro 2006. The towers are designed in two wind zones I & V with three different base widths 1/4, 1/5 &1/6 of total height of tower. Towers are modeled using parameters such as constant height, bracing system, angle sections and variable parameters of different Base widths and Wind zones. The loads are calculated from IS: 802(1995). After completing the analysis, the comparative study is done with respect to deflections, stresses, axial forces and weight of tower for all 6 different towers.
