The Timber Tie Beam: The Analysis of Spatial Framework Joint

The popularity of timber buildings is increasing at the moment. Timber is used as a main material for constructions of buildings, bridges and towers. Especially halls or office buildings need a construction of roof made by tie beams. Using of steel fasteners is quick, cheap and secure solution of joints in timber frame construction. There was a requirement for visible tie beam. For this reason the special joints by nogs were created, to design aesthetical and secure construction. This work studies a spatial frame work of unique timber tie beams. Their construction is engineered by four beams in two mainstreams. The critical point in the construction is a spatial joint in the cross of the beams. Therefore the FEM models have been created. The FEM results are compared with a real load test, performed on a real timber model. That way, we were able to monitor the critical spatial joint.
