Structural Behaviour of Transmission Tower with Different Bracings under Wind Loading

Abstract

Abstract: India has a sizable population that is dispersed throughout the nation, and this population's high need for energy production results in the need for a sizable transmission and distribution system. The present work for the design of transmission towers with foundations for two distinct zones, each with a different basic wind speed and kind of terrain. The requirement of the members has also been optimised. With the aid of Staad.pro and MS Excel's VBA, this present work has completed. Three distinct bracing systems were contrasted based on a number of factors, including deflection, weight, the quantity of joints, and cost. STAAD.pro has used to analyse the tower under various loading conditions, and Excel-VBA interface has used to construct the connections and base. The technological analysis and economic design of transmission line tower constructions have been the main aims of the present work. Under the specified loading conditions scenarios for both zones, the K bracing tower showed the least deflection in terms of the deflection criterion.
