The purpose of this study is to establish a computational morphogenesis method for unreinforced concrete shells. In this study, the morphogenesis method in which only body force such as gravity and seismic inertial forces act on the rectangular parallelepiped design domain is used. By such a method, various optimum shell morphologies can be created simply by giving the boundary shape that supports the shell. However, the method (IESO) proposed in Reference 7) did not accurately consider the effect of body force on the element sensitivity number. Therefore, in this paper, we improve the element sensitivity number of IESO method by adding the sensitivity of body force. In order to verify the effectiveness of the improved method, we show analysis examples in which the support boundary of the shell is square or rectangle.
