Abstract
This paper describes generation of a spatial frame structure from 2dimensional frame that is spread by irregular hexagons. The method to generate the frame structure is shown by operation of nodal point in the frame. First, when vertical load is imposed to the frame in plane, displacements occur in every nodal point. The node where max displacement occurred is raised in the upward direction by a unit length. Thereby the shape will have a convex out of the plane, and displacement will be reduced. Repeatedly, the shape will have an irregularity and complexity, and will be deformed hardly gradually. Finally, although the volume of members increased, the displacement of nodal point is reduced very much. It seems a new structure that has an irregularity and complexity that can be seen in nature.
