Abstract
In this study, we propose a method of optimizing a tree-type support structure, considering the aesthetic effect, to evolve the structure to a rationalized form. The initial shape is generated using the fractal geometry, and the B-spline curve is used to generate the boundaries and cave of the free-form shell. It is shown in the numerical examples that the strain energy of overall structure can be reduced by optimizing the shape of the tree-type structure.
