I have modeled a continuous beam. One of the supports should only act as of the deformation of 10 mm. How can I set such a nonlinearity?

Answer

In this case, it is recommended to use the definition of slippage. For this, select Partial Activity as a "Nonlinearity" in the "Edit Nodal Support" dialog box. In the "Nonlinearity - Partial Activity" dialog box, you can define the slippage in the respective zone. For checking purposes, there is a diagram, see Figure 01.
