The presence of flying buttresses exposes the obvious structural skeleton of a large Gothic cathedral, but any masonry structure hides a skeleton of some sort. This engineering structure may be determined by very simple statics, and the whole analysis can be interpreted by the use of the “safe theorem” of plastic theory.

Until his retirement Jacques Heyman was Professor and Head of the Department of Engineering at the University of Cambridge. He is the author of sixteen books and co-author of two others, and has written numerous articles on the plastic design of steel structures, masonry construction, general structural theory, and the history of structural engineering. He is a Fellow of the Society of Antiquaries, of the Institution of Civil Engineers and of the Royal Academy of Engineering. He has been the Consulting Engineer for the repair of a large number of English cathedrals and churches. Professor Heyman was for many years a member of the Architectural Advisory Panel for Westminster Abbey, and of the Cathedrals Fabric Commission for England.
