“…Conversely, for partially anchored framed walls, the mechanism of 'separation' between studs and beams, due to the overturning moment, must be taken into account. Such a separation mechanism can be modelled by using pairs of horizontal and vertical springs at each stud-to-beam connection [15] in which the corresponding load-slip curves describe connection behaviour under horizontal (i.e. shear) and vertical (i.e.…”

A new method to assess the raking performance of Platform timber framed walls, is provided in this study: each component of the unit wall assembly is assumed as rigid, hence allowing to drastically reduce the overall number of DoFs involved within the model. The timber frame in particular, is modelled as a mechanism, having only two DoFs (regardless of the number of studs) corresponding to the horizontal and rotational displacements of the header beam. For a given imposed horizontal displacement ∆ h , the corresponding racking load P (∆ h ) is computed by numerical relaxation, allowing to consider a continuous function to represent the load-slip curves of the connections. A comparison of the numerical analysis against laboratory test results is provided, showing the method's capability in predicting the raking strength of the wall, despite the assumed reduced number of DoFs.
