The presented work deals with the field of optimization of steel bar towers with the use of topological evolutionary structural optimization. The problem is fully addressed in the work, first using the pre-processor for determining the basic construction or the initial design space, within which the proposed optimization method is then used to search for the optimal distribution in the size of the elements. The pre-processor represents the implementation of an expert system and its development of the assessment of an engineering - acceptable initial construction, taking into account the impacts of the environmental loads on the design. Its use determines the design area, which, in the case of columns handling is limited by basis dimensions. The initial distribution of elements within the tower is determined according to the altitudinal cuts of the structure, which depend upon the loading. The optimization approach ensures the appropriate distribution of size of the elements inside the structure. Own developed computer program enables numerical analysis, optimization, and 3D visualization of topologically optimized steel bar towers.
