Abstract
Metaheuristic evolutionary methods are powerful tools for solving non-linear, many dimensional optimisation problems. In this article, one of these methods is combined with finite element method for optimising truss like structure. The advantages of the combined method are presented through a real engineering task, optimisation of transmission line tower. The design of the latter can take a variety of shapes, so in the present case, only the lower part can be optimised. For optimisation, we use the adaptive differential evolution (SaDE) technique. The objective function of the optimisation is the mass of the structure. Finite element analysis is used to determine the stresses. The overall and local buckling constraints have also been considered.
