Structure in Architecture is appearing in diverse forms composed of diverse materials, constructed by diverse methods, and exposed to diverse impacts. If we could compose a single structural design method and morphology for those complicated targets, we would be able to design more material oriented forms based on shape of elements, nonlinear phenomenon, geometry, craftsmanship and energy consumption. It would also be valuable for us to make engineering decisions in design situations including unknown phenomena, or in instances where we attempt to design and construct forms that are so complicated, they are even difficult to draw.
