Using finite element methods to analyze ancient architecture: an example from the North American Arctic

Developing theories of vernacular architecture in archaeology has been hindered by the lack of a defined methodology for studying ancient buildings, and the absence of information on the mechanical properties of construction materials uncommon in today's building practices. In this paper we use Finite Element Methods and recent research on the structural properties of whalebone to analyze the architecture of Thule semi-subterranean houses. These unique dwellings were constructed and used by the ancestors of Inuit/Eskimo peoples in the Canadian Arctic and Greenland. Little is known about how they were designed and constructed because few have ever been discovered intact. The substantial weight of whalebone roof frames suggests that some designs would have performed better than others. Poorly planned houses, or the use of whalebone in a symbolic rather than strictly utilitarian capacity, may have resulted in higher maintenance costs, thereby shortening their anticipated use life. In extreme cases, errors in design, or the failure of materials may have caused dwellings to collapse, resulting in injuries or possibly even death. We demonstrate through this case study that Finite Element Methods constitutes an effective methodology for studying ancient buildings, with the proviso that more research is needed on the mechanical properties of building materials used in the past.
