On the design of a kinetic adaptive structural surface with reference to nature, form and simplicity

Abstract

The central thrust of this thesis is that there is much to learn from Nature. What surrounds us, and has been with us from the beginning of time, still has many insights to offer, if we are only willing to look. In Nature, shape is cheaper than material. Forces and form are continuously linked and the concept of adaptability is central to survival. Many of our designs, in contrast, have been over-designed, unresponsive and unchangeable. This thesis covers how well thought through form can yield impressive benefits which, in combination with adaptability, can create structures that are efficient as well as beautiful. Specific forms in Nature are discussed as well relevant historical examples from the built environment; including new work in deployable structures. As an example of these concepts, a kinetic adaptive structural surface was designed and built. This responded to applied loads by actively changing its shape. The thesis concludes with a discussion on emergence as one of the ways ahead for structural design that involves distributed sensing and control.
