Considering Elastic Slip Modulus of Timber Connection
Tips & Tricks
For a timber connection, as shown in Figure, you can take into account the torsional spring rigidity (spring stiffness for rotation) of the connections. You can determine it by means of the slip modulus of the fastener and the polar moment of inertia of the connection. For the ultimate limit state design, you must use the design value of the slip modulus for calculation, and the mean value for the serviceability limit state design, and therefore you obtain two torsional spring rigidities.
To take into account both rigidities, activate the “Modify Stiffness” subtab (select the corresponding check box in the “Calculation Parameters” subtab of the “Load Combinations” tab in the “Edit Load Combinations and Calculations” dialog box). As in this example, this allows you to multiply the torsional spring rigidity for all SLS combinations by a factor (1.95). Thus, you can calculate with a torsional spring rigidity of 863 kNm/rad in all ULS combinations and with 1,684 kNm/rad in all SLS combinations. The elastic torsion of the foundation is not taken into account in this example.
