In this paper, there are two objectives in the optimisation of thin-walled structure, one of these is to reduce the total mass of the structure, and the other is to ensure the carrying capacity of the structure. The secondary objective, i.e. carrying capacity, is transformed into the optimisation constraints by Constraining Method. The structure is optimized by modifying the thickness of the plate. The finite model is created using ABAQUS/CAE in the visual environment. Then the maximum carrying capacity is calculated by buckling analysis, and used as the applied load in the static analysis. The optimisation software is written by VC ++, which can automatic read the output of ABAQUS data file and use the maximum stress in each plate as a critical stress to calculate the corresponding thickness. Then a new ABAQUS input file with the new plate thicknesses is created by the software. The structure described in the example of this paper finally obtained a minimum mass with great carrying capacity, after six times of optimisation
