 Hierarchal Structure Lucy Zuo Nature holds many lessons for creating extremely light-weight but strong structures. The natural hierarchical structure refers to the use of geometrical structure instead of material for strength and elasticity, significantly reducing the amount of material needed to address the functional challenge. Unlike man-made structures, wood, tendon, bamboo and bones all share inherent heterogeneity of biological materials and hierarchical composition, which are known to enhance material properties such as elasticity, damage tolerance and toughness. Giant Danish water lilies are known for their thin structures, but can support the weight of a child. The rigidity is provided by the radiating rib structures and furrow configuration.
