Structural Hierarchy in Spider Webs and Spiderweb-Type Systems

The orb-web of Araneus diadematus exhibits three forms of hierarchy in its structural design: relative stifiess, prestress, and geometric stiffness. These experiments showed that all forms have the potential to influence the flow of internal forces through this natural tension structure, but relative stiffness is unquestionably the dominant factor. The lightness and eficiency of a spider web appear to be related to its structural hierarchy. L.H. Lin and Professor Dr-Ing. W. Sobek
