Description of the research topic:
Gothic architecture applies several geometrical construction rules that regulate the relations of the different dimensions of the structure to each other: length of the pointed arc is related to the thickness of its supporting pillars; height of buttresses is related to its width etc. These geometric rules formulate a complex system, and the individual rules can be interpreted only in harmony with each other. (This explains the usual experience why cathedrals built on the same geographic region around the same time are rather similar to each other in appearance: the same set of rules were applied in their construction.)
Though these rules were originally based probably on aesthetic and philosophical principles and on trial-and-error experiences, only those rules could survive the centuries which led to structures that turned out to be stable under the usual effects like selfweight, meteorological loads and at least minor soil movements. However, the mechanical background of these sets of rules is still unrevealed today. The PhD research should interpret these rules in the frame of modern mechanics, and reveal the statics principles and probable experiences that are hidden behind these rules. Particularly vulnerable parts of Gothic structures could also be indentified this way.
The first step of this research is to collect the gothic construction rules that can be found in the literature. Their statical background is to be understood and criticized. Then modern numerical techniques should be applied to simulate the mechanical behaviour of Gothic structures or structural members under the typical loads of masonry structures, in order to assess the reliability of the considered rules.
3DEC discrete element code, and if needed, ANSYS finite element code are available for performing the research. Demonstrated previous experience in using a discrete element code with polyhedral elements is indispensable.
