In this paper, a ground structure approach for computational morphogenesis of building structure is shown. In this method, it is difficult to obtain exact solutions by general non-linear programming methods when the members of ground structure increase. In this paper, some examples that the solution dose not converge to exact solution are shown, and a method for solving this problem is proposed. In the proposed method, SLP or CONLIN method is used as solver of the optimization problem. Several numerical examples are presented to demonstrate the effectiveness of the proposed method. Also, it is shown that this method can be used for computational morphogenesis of building structure.
