This paper presents a numerical analysis method for shape optimization problems of cross section in three dimensional frame structures made of thin plate. The beam theory was applied for frame segments. Cross section was assumed as rectangle with height and width. The distribution functions of the height and the width defined on frame structures were chosen as design variables. With respect to stiffness maximization problem, numerical analysis method of shape gradient function was presented by applying the adjoint variable method. Using the shape gradient function, a program for three dimensional frame structures based on the gradient method was developed. The performance was demonstrated with some numerical results for three dimensional frame structures.
