| Description
| - The Assessment and design of mechanical behavior of joints used in historical timber constructions such as churches, castles etc., is currently paid a big attention in the Czech Republic. The reasons are a) a high number of such structures in the area central Europe; b) missing information about how certain types of historical joints respond to mechanical loads and how to design them from structural point of view. During reconstructions of valuable timber structures there are requirements for very sensitive approach with respect to cultural value, specific environment conditions and preservation of most of original material. The way to fulfill these requirements is to replace damaged parts of beam members by insertion of a new wooden element with the use of traditional all-wooden joints for joining to original structure. Such approaches call for complex mechanical analysis of structure including joints. This article presents one of the numerical approaches that can be used for assessment of historical structures and all-wood joints used in historical structures – reduction analysis using finite element analysis. Using this approach a part of historical structure is analyzed as truss and the joint part is solved as 3D solid body. The FE model in ANSYS software assumes orthotropic material properties of wood (Norway spruce) and elastic behavior, the contact in joint is flexible-to-flexible and symmetric. Results of the FE analyses show the reduction technique efficiently determines global mechanical behavior of the roof structure of gothic St. James's Church in Brno, Czech Republic as well as detailed stress state of the joint reflecting boundary conditions from truss.
