Saving and Importing Diagrams for Member Hinges

Technical Article on the Topic Structural Analysis Using Dlubal Software

Technical Article

In RFEM 5 and RSTAB 8, you can assign nonlinearities to member hinges. In addition to the nonlinearities "Fixed if" and "Partial activity", you can select "Diagram". If you select the "Diagram" option, you have to specify the appropriate settings for the activity of the member hinge. For the individual definition points, it is necessary to specify the abscissa and ordinate values (deformations or rotations and the according internal forces) that define the hinge.

Depending on the number of defined points of a diagram for the member hinge, the necessary input can be quite extensive. To reduce the time for specification, you can save the specified diagram. If you want to insert a new member hinge (also with the "Diagram" nonlinearity) at other member ends, you can import this saved diagram.

This functionality works across models, thus allowing you to import the defined diagrams in other RFEM and RSTAB models.
