This paper studies the structural optimization with robustness for buckling of FRP laminated circular cylindrical shells. For this purpose, the buckling equation under axial compression is derived based on the classical lamination theory, and multi-objective optimization problem is defined by taking a critical buckling load and a sensitivity of the load as objective functions, and the bucking load and the sensitivity would be maximized and minimized simultaneously, respectively, by optimizing the stacking sequence of the shell. In optimization, a vector evaluated genetic algorithm is employed to solve the optimization problem. In numerical calculations, the pareto optimal solutions are obtained for the present problem, and the applicability of the GA employed is also studied from numerical results obtained.
