The initial question is answered using a parametric study. The methodical approach of the parameter study is based on finite element modeling, which is described in great detail and checked for plausibility. The necessary number of wall models for the parameter study is generated by programming a tool with a visual programming language. The evaluation of the parameter study allows for making correlations between the geometry of a timber panel wall with an opening, and the deformation of the wall under a constant load. In addition to the area of the opening and the geometry of the opening, it has been shown that the positioning of the opening in relation to the rib grid of the wall affects the stiffness. The opening height can also have a strong influence on the stiffness, although it is not included in the design according to Eurocode 5.
Finally, the individual wall structures are analyzed in more detail for possible reinforcement according to the North American construction model. The analysis showed that the reinforcement is particularly useful for walls with high loading. First hypotheses are made for a final evaluation of the significance and the question to which improvement the reinforcement leads. In addition to these hypotheses, data gaps in the field of fasteners that were uncovered during finite-element modeling also provide opportunities for research.
