Abstract

AbstractTransmission towers have been playing an important role in the power sector. This study isfocused on optimizing the steel transmission towers using firefly algorithm. Metaheuristicshave been widely in use during the recent past. The design of cross sectional areas of themembers is modeled as a continuous variable to determine the optimal values. A newapproach is designed to perform optimization process. This study does not include using ISsteel sections from the steel tables. The planar linear static analysis of the steel tower isconducted first and the linear buckling analysis is conducted using Midas FEA. The maximumstresses and displacements in the tower are compared against the allowable stresses anddisplacements. The positive buckling load factors were determined and the mode shapes wereplotted. IS 800 code checks were performed and the results presented towards the end.Keywords: Transmission towers, firefly, structural optimization, bucklingCite this ArticleAnvesh Reddy A, Ch.
