This study is devoted to the optimal design of compressed columns with a circular cross section under axial compressive forces and exposed to a corrosive environment. The initial volume of the structure is taken as an optimality parameter. The main constraint is the buckling of a loaded column at the final time of its operation. Gutman-Zaynullin’s exponential stress corrosion model is adopted for the analysis. Analytical and numerical results are derived for optimal variation of the cross-sectional area of the bar along its axis.
