You must specify if the connection is a Simple Joint or a Moment Resistant Joint. 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 Moment Resistant Joints category provides the following design variants:
|
End plate without column |
|
Beam joint |
|
Single-sided beam on column |
|
Double-sided beam on column |
|
Purlin joint |
The Simple Joints category provides the following design variants:
|
End plate |
|
Angle cleats |
|
Angle cleats and large gap |
|
|
Purlin splices |
The Perform ductility check check box is available for simple joints. You can use it to check whether the connection to the load-bearing components fulfills the ductility criterion according to the European Recommendations for the Design of Simple Joints in Steel Structures . This aims to prevent a premature and brittle failure before complete formation of the hinge in the connection.
TIP
It is only checked whether the design criterion for the bolts to the plate of the load-bearing structural component is fulfilled. The remaining components of the joint – angles, bolts on the connected structural component, and the connected component itself – are not checked, although they greatly influence the ductility as well!
