Background
After a short spell in industry, I joined the University of Warwick in 1986, where I am based to this day. I am a Professor in the School of Engineering, University of Warwick, a chartered civil engineer, a Fellow of the Institution of Civil Engineers, and the Royal Society of Arts. My 30+ years of research experience is reflected in the monograph 'Tension Structures: Form and Behaviour' (review)Link opens in a new window, numerous research and technical press articles, and international lectures. Having studied tension structures extensively, I learnt about the importance of structural form in response to load and a process of FORM-FINDING that implements natural principles in structural design. It is a process of shaping structures by applying, or controlling stresses developing in them under statistically prevalent load. Such structures comply with ‘form follows force’ principle observed in the formation of natural objects, such as trees, bones, shells. My work on structural forms shaped by biomimicry in form-finding is reflected in documentaries, podcasts, press releases and international lectures.
My work on computational form-finding of flexible fabric structures progressed to analytical form-finding that predicts optimal shapes of rigid structures, such as arch bridges, for example. This work challenges conventional design approaches that use imposed structural forms and rely on the limit state design philosophy alone.
I have led a number of national and European research projects in collaboration with industry (Arup, Jaguar, Roll-Royce, SL-Rach, Canobbio) as well as multi-disciplinary projects, such as 'Designing for the 21st Century' - in collaboration with the Courtauld Institute of Art, London.
Research Activities
My research is concerned with FORM-FINDING related to: Conceptual Design of Fabric StructuresLink opens in a new window, Minimal Structures and NatureLink opens in a new window, Structural Form in Engineering, Nature and Art.Link opens in a new window
The essence here is to achieve optimum structural forms by using nature’s own design principle that ensures minimal stress response to loading.
My work on natural structural forms progressed beyond flexible tension structuresLink opens in a new window and includes rigid-type objects, such as arch bridges (Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016, 472 (2190)Link opens in a new window).
Its results challenge established optimisation criteria and conventional design approaches that use imposed structural geometries in conjunction with ultimate load as part of Limit State Design philosophy
Biomedical work on shaping minimal scaffolds for bone replacement awaits potential application.
Past research relevant to the automotive and aerospace industries included the convertible roof for the Jaguar XK8Link opens in a new window, and, at a feasibility level, compressor blades (Engineering Structures 2011, 33, 9, 2612–2620).
