You have to specify whether the joint is a Bracket or an End plate. Sikla refers to the latter as an "End Support". You can select the category by using the drop-down list or clicking the buttons with the connection icons.
The available options depend on the joint category.
The Bracket category provides the following design variants:
|
Cantilever bracket – type AK |
|
Beam bracket – type TKO |
The End plate category provides the following design variants:
|
End support – type STA |
|
End support – type WBD |
|
Corner bracket – type WD |
There are no setting options in this section. The connections are designed according to German Expert Opinion (GS) with Test Report No. K14-6005-3.
Sikla's installation guidelines for connections contain information about the permissable load capacity of typical Sikla structures for building equipment and industrial and plant construction. They are available for download on the manufacturer's website.
EN 1993 does not give any clear recommendations for scheduled torsion. The two check boxes allow you to completely Ignore the torsional stresses or neglect them up to a user-defined limit. 5% is preset as the maximum ratio of the existing torsional stress τt,Ed to the torsional shear resistance τt,Rd. If the value is exceeded during the design, a corresponding error message appears.
