Abstract
To carry power lines from one place to another place at sufficient and safe distance from ground level transmission towers are constructed. This paper presents the most economical and efficient section as per Indian standard IS 800 for design of tower. The present work describes about analysis and design of four legged self-supporting transmission tower with different sections such as angular and tubular sections. The transmission tower has a height of 35m and base width of 10m. The wind force plays an important role on the tower elements besides the self-weight. This study shows that the tower with the angular section is most effective and economical section compared to tubular section for different bracing such as X, K and W.
