3.2. Numerical modelling Numerical models were created to take into account the boundary conditions and the real geometry of the tested wall panels and the auxiliary external steel structure. The numerical model also incorporates the anchorage of the wall panel to the lower reinforced concrete beam using the LVL plank, steel connectors with screws, and anchors. The connections between elements were modelled with eccentricities and slips (Carcamo et al. 2018, Vogrinec et al. 2016). The following figures illustrate the horizontal deformation of the panel with horizontally oriented OSB boards and unglued tongue-and-groove joints A01 (see Fig. 7). The deformations correspond to a load of approximately 21 kN.

The graph in Fig. 8 shows a comparison of the load-deformation diagrams obtained experimentally and from numerical analysis for the wall panel with horizontally oriented OSB boards with unglued tongue-and-groove joints
