The goal of this study is to evaluate the effectiveness of using more than one material for unit element flange of Archigird. The flange is optimized using the solution of multi-material topology optimization. In this topic, multi-material minimum structural compliance topology optimization problems is solved basedon the classical optimality criteria method. Three different types of steel material are used: SS400, SM570, UL700. The distribution of these three materials is considered by changing the participating volume of materials in the given shape. Material distribution is implemented with the use of 2 materials and 3 materials. The strain energy and the price of three steel types are used for comparison.
