Abstract
This thesis explores the challenges faced by engineers when presented with a highly complex and fixed volume to support and fill with structure. This situation may arise in the design of free-form architecture, around existing buildings or within large-scale sculptures.An interactive software application based on a particle simulation moving between matter states from gas to liquid to solid was developed. Combinations of simulated Brownian motion, inter-particle and environmental forces were used to imitate each state. Various algorithms, including a real-time adapted Delaunay tetrahedralisation and a recursive bounce routine, were implemented and used to create stable space frames that fit within any imported volume.
A novel technique called freeze-thaw optimisation is introduced and initial tests that produced a reduction in deflection for a range of space frame support conditions are presented.
The technology was successfully implemented as a case study to design a roof structure for the upcoming Tallinn Town Hall project by BIG architects and Ramboll UK.
This research has significance beyond structural space frame design, including finite-element meshing, optimised cellular or foam metals, bespoke furniture design and computer animation.
