Comparison of Two Medieval Trusses from the Viewpoint of Geometric and Static Analysis

Abstract:

The subject of article is a comparison of two load bearing structures of medieval trusses in terms of their original design, based on the geometrical concept, as well as from the perspective of their current static analysis, based on modern, standardized calculation procedures. It is a roof above the sanctuary of the Roman Catholic Church in the village of Bela-Dulice from 1409d, and a roof above the sanctuary of the Church of St. Peter of Alcantara in the Franciscan monastery in Okolicne from 1499d. From a typological point of view, both the trusses have a similar rafter collar-beam construction with longitudinal stiffening frame truss and with approximately the same span. In the case of the monastery church in Okolicne, the construction of main cross truss is supplemented by the spike struts. From the geometric analysis of trusses there are obvious different geometric proportional relationships that have been applied in the original design. The aim of static analysis of the load bearing structures using current advanced computing resources is to clarify and compare the static behaviour of the both roof structures.
