A brief history of the structural optimization is given. The developed system of minimum cost design is described. In 1970’s a school has been found for structural optimization in the University of Miskolc. The advantages and disadvantages are compared for the design by routine and those of optimum design. The problem of interaction of two instabilities is treated with the conclusion that the optimum design is safe when the used stability constraints take into account the effect of initial imperfections and residual stresses. Some own results are detailed about the optimum design for different structural types such as compressed and bent columns, stiffened plates as well as wind turbine towers. A literature survey is given for optimum design of trusses, frames and industrial applications.
