This connection is a purlin-truss or purlin-steel beam connection . When purlins are defined, the program makes these connections automatically. However, the connection made automatically can be deleted and a new one can be made.

Location of the Purlin Connection Command

You can access it under the Ribbon menu, Connection tab, Experimentals title.

Usage Steps

  • From the Connection menu, click the Purlin Connection icon.

  • Click the beam or truss, then the beam, respectively, from the 3D perspective view.

  • The connection will occur with default settings.

Location of the Purlin Connection Settings Dialog

Select the connection and click the right mouse button. Click the Properties line from the right click menu that opens.

Welds Tab

Specifications

Welds

The thickness, type and angle values ​​of the welds to be made at the connections are given. The information on whether it will be done on the construction site or not is entered.

Weld electrode

The strengths of the welding electrodes are defined in the design inputs. The strength of the main element in the weld joint is controlled under the condition that it has less strength than the weld strength.

If necessary, click the list and define "Create New…". To create the welding electrode, give the information "Name" and "Weld metal tensile strength" in the dialog that opens after clicking "Create New".

Welding geometry is determined automatically by the program. These properties can be changed to easily determine the connection properties. Geometry features are in accordance with industry standards and in the form specified in AISC.
