Scaffolding Nodal Support – Diagram with Gap

The advantage of the RFEM 6 Steel Joints add-on is that you can analyze steel connections using an FE model for which the modeling runs fully automatically in the background. The input of the steel joint components that control the modeling can be done by defining the components manually, or by using the available templates in the library. The latter method is included in a previous Knowledge Base article titled “Defining Steel Joint Components Using the Library". The definition of parameters for the design of steel joints is the topic of the Knowledge Base article “Designing Steel Joints in RFEM 6".

Steel connections in RFEM 6 are defined as an assembly of components. In the new Steel Joints add-on, universally applicable basic components (plates, welds, auxiliary planes) are available for entering complex connection situations. The methods with which connections can be defined are considered in two previous Knowledge Base articles: “A Novel Approach to Designing Steel Joints in RFEM 6" and “Defining Steel Joint Components Using the Library".

You can use the Steel Joints add-on in RFEM 6 to create and analyze steel connections using an FE model. You can control the modeling of the connections via a simple and familiar input of components. Steel joint components can be defined manually, or by using the available templates in the library. The former method is included in a previous Knowledge Base article titled “A Novel Approach to Designing Steel Joints in RFEM 6". This article will focus on the latter method; that is, it will show you how to define steel joint components using the available templates in the program’s library.

You can now insert a cap plate in steel joints with only a few clicks. You can enter the data using the known definition types "Offsets" or "Dimensions and Position". By specifying a reference member and the cutting plane, it is also possible to omit the Member Section component.

This component allows you to easily model cap plates on column ends, for example.

You can use the "Plate Cut" component to cut plates (for example, gusset plates, fin plates, and so on). There are various cutting methods available:

• Plane: The cut is performed on the closest surface to the reference plate.
• Surface: Only the intersecting parts of plates are cut.
• Bounding Box: The outermost dimension consisting of width and height is cut out of the plate as a rectangle.
• Convex Envelope: The outer hull of the cross-section is used for the plate cut. If there are fillets at the corner nodes of the cross-section, the cut is adapted to them.

In the Steel Joints add-on, you can perform precise cuts on plates and structural components using the "Auxiliary Solid" component. Within this component, you can use the shapes of a box, a cylinder, or any cross-section as a guide object.
