Standard Parameters

For some standards, the Standard parameter tab of the 'Ultimate configuration' or 'Strength configuration' dialog box is available. All coefficients that are relevant for the designs are listed here.

The 'Design settings' are aligned with the sections of the respective standard. The following sections describe the parameters of these standards:

1. EN 1995
2. NDS
3. CSA O86

EN 1995

Tab “Standard Parameters” for Timber Design According to EN 1995

All coefficients relevant for the selected national annex are listed. The default setting corresponds to the standard specification or the recommendation. The 'Note' column shows the section of the standard to which a parameter refers. Reduction factors are automatically taken into account by default, whereas increase factors are not activated. You can activate the corresponding coefficients by ticking the check boxes if the requirements are fulfilled. In this way, for example, favorable factors for laminated veneer lumber can be taken into account in the designs.

If it is necessary to adjust a coefficient, you can also define it user-defined. The stress distribution factor k_dis plays a particularly important role for duopitch roof beams in order to take into account effects of tensile stress perpendicular to the grain for curved cross-section distributions.

NDS

Tab 'Code Parameters' for Timber Design According to NDS

All coefficients relevant for the design according to NDS are listed. The default setting corresponds to the standard specification. The 'Note' column shows the section of the standard to which a parameter refers.

CSA O86

Register 'Standard parameter' for Timber design according to CSA

All coefficients relevant for the design according to CSA are listed. The default setting corresponds to the standard specification. The 'Note' column shows the section of the standard to which a parameter refers.
