Abstract
This study explores an innovative method in structural morphogenesis. It is based on the self-adapting function of a net-shaped mechanism system. A net-shaped mechanism system was developed first by adopting B-spline curves for the member geometry, followed by an equation of the control points motions which constrains the length of each member within the net-shaped system so they remain unchanged as the shape is adapted. This equation is solved using the generalized inverse matrix theory together with a principle of maximized gradient of potential energy increment with the system shape variation. An iterative process is used to find the final shape of the mechanism system, which corresponds to an optimized structural shape featuring a predominant axial force and a small bending moment under the specific loading pattern applied to the mechanism system.
