Abstract


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. Metaheuristics
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
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. 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.
Keywords: Transmission towers, firefly, structural optimization, buckling
