Since structural topology optimization using the homogenization method was introduced by Bendsoe and Kikuchi in 1988, this method has been applied to the various kind of problem and also become one of the CAE tool at the begining of conceptual design in many industries. However, the result of optimal topology calculated has unclear part such as gray zone or checker-board type density distribution. Many researchers studied various kinds of methodology to obtain the clear configuration from the result of topology optimization. In this paper, we introduce the new type of unit-cell so called 'Frame based unit-cell' to improve the result of optimized topology. Some examples resulting from the proposed method are presented and compared with the density approach and the homogenization method which are widely used in the structural topology optimization.
