For some standards, the Beam panels | Connectors tab of the 'Ultimate configuration' or 'Strength configuration' dialog is available. Here you make basic settings for the design of the fasteners and sheathing of beam panels.
The 'Design parameters' are divided into several subcategories, which differ depending on the design standard. The following sections describe the parameters of these standards:
EN 1995
Surfaces | Beam panels | Sheathing-Rib-Connector
By default, no smoothing of the connector forces is applied, so that each fastener is designed with its share of the force. If the shear flow is to be "smoothed" over the length of the line hinges, select a linear or constant distribution of the forces.
The other subcategories offer setting options for design-relevant parameters of the connectors. The corresponding sections of the standard are given in each case.
You can reduce the thickness of the sheathing by 2 mm if there is a weakening due to the penetration depth of nail heads or staple backs. This option is described in the German Annex NCI to 8.3.1.1 (NA.14) or NCI to 8.4 (NA.11). Furthermore, you can take additional stresses into account in a simplified way in the sheathing design using factors kv2 for single- or double-sided sheathing, for example for purlin joints.

By default, no smoothing of the connector forces is applied, so that each fastener is designed with its share of the force. If the shear flow is to be "smoothed" over the length of the line hinges, select a linear or constant distribution of the forces.
The other subcategories offer setting options for the factors for shear resistance for ASD and LRFD. There you can define, for example, correction factors for load duration and time effects, reduction factors for earthquake or wind, and other drag coefficients.
