Abstract
In this paper, an improved ESO (Evolutionary Structural Optimization) method for topology optimization is applied to biomimetics in architecture. In the proposed method (hereinafter called IESO), the idea of BESO method and the idea of extended ESO method are combined. However, IESO method is one-directional approach similar to the earlier ESO method, that is, it does not have the additional algorithm of elements. Therefore, this method is computationally efficient, and moreover more natural morphology can be obtained in comparison with SIMP method. Also, if a finishing algorithm is added to this method, it is possible to obtain the result which the objective function is better than SIMP method. Several numerical examples will be shown in order to demonstrate the effectiveness of the proposed method, and the effectiveness for the application to biomimetics.
