ABSTRACT
The period of the National Revival in Bulgaria in the 18th and 19th century gave rise to a wide array of traditional constructive systems. The system known as posts-and-planks has not yet been thoroughly researched, specifically in its aspects of structural behavior. This paper hypothesizes the origin of the posts-and-planks houses in the region and presents two specific tectonic features of these buildings – tilting of the enclosing walls and T-shaped junctions of the walls. The article describes the tectonic repercussions of these constructive particularities. The article raises the question of the danger of losing tectonic authenticity during restoration works connected with the future reuse of post-and-planks buildings due to the specific “invisible tectonics” of the two presented constructive features.
