Geometric and Static Analysis of the Historical Truss above Presbytery of the Saint Peter of Alcantara Monastery Church in Okolicne

Abstract

The truss of the Franciscan monastery church of Saint Peter of Alcantara in Okoličné represents one of the few well-preserved medieval structures in this region. The geometrical analysis of the main roof truss as well as the central longitudinal truss is based on logical dependencies and a description of a process in the truss design, pointing to evaluative relations resulting especially from the Pythagorean Geometry. On the basis of the mutual interdependence of the transverse links and central geometrical frame stool we can determine the sequence of key points and reciprocal relationships. Consequently, a spatial numerical model of the roof structure was created in order to perform a static analysis of the roof structure in accordance with present standards. With regard to the structural analysis results, it can be said that the original design of the structure based on geometrical principles satisfy the reliability conditions defined by current European standards for structural design.
