Abstract

Transmission towers have been playing an important role in the power sector. This study is focused on optimizing the steel transmission towers using firefly algorithm. Metaheurisitcs have been widely in use during the recent past. The design of cross sectional areas of the members is modeled as a continuous variable to determine the optimal values. A new approach is designed to perform optimization process. This study does not include using IS (Indian Standard) steel sections from the steel tables. The planar linear static analysis of the steel tower is conducted first and the linear buckling analysis is conducted using Midas FEA (Finite Element Analysis). The maximum stresses and displacements in the tower are compared against the allowable stresses and displacements. The positive buckling load factors were determined and the mode shapes were plotted. IS 800 code checks were performed and the results presented towards the end.
