Sammanfattning
This thesis investigates, develops and proposes finite-element modelling strategies
for timber shear walls constructed as timber frame walls and cross-laminated timber
walls. The thesis recommends various techniques to reach reliable results and at
the same time reduce the modelling efforts. Studies are made on the effects of
scaling the structure to multiple floors as well as the influence of the length of
the individual wall elements. Discussions are made on the behaviour of the different
modes of deformation and it is found that there is a significant potential to reduce the
calculated deformation of timber shear walls by taking into account the friction to the
foundation or floor as well as considering the weak axis strength of shear and tension
connectors. Further a discussion is held concerning modelling strategies suitable for
linear dynamic analysis and recommendations are made to take precautions of how
the non-linearities in the model are linearized in the analysis.
