Chapter 2.8 Arches, Vaults and Domes
Compression structures are ubiquitous as traditional bridges, cathedrals and viaducts. They have been adopted in modern forms using steel, concrete and timber. Traditional forms of vault and arch are reviewed, leading from a simple bridge with a single arch to multiple arches and to a simplified analysis of a cathedral buttressed section. Finally, the reader is invited to try out the methods of simple analysis to size a steel arch structure (based on a real stadium roof). By way of this example step by step conceptual design short cuts are followed to illustrate the way that a practising engineer might conceive a design without the use of a computer.
