The transition from experimental studies to the realm of numerical simulations is often\nnecessary for further studies, but very difficult at the same time. This is especially the case for\nextended seismic analysis and earthquake-resistant design. This paper describes an approach to\nmoving from the experimental testing of an elementary part of a wood-frame building structure to\na numerical model, with the use of a commercial engineering analysis software. In the presented\napproach, a timber-frame structure with polyurethane (PU)-foam insulation and OSB (oriented\nstrand board) sheathing was exposed to dynamic excitation. The results were then used to generate\na numerical 3D model of the wooden frame element. The process of creating the 3D model is\nexplained with the necessary steps to reach validation. The details of the model, material properties,\nboundary conditions, and used elements are presented. Furthermore, the authors explain the technical\npossibilities for simplifying the numerical model in used software. Simplifying the model leads to a\nsubstantial reduction of calculation time without the loss of accuracy of results. Such a simplification\nis especially useful when conducting advanced numerical calculations in the field of seismic and\ndynamic resistant object design.
