Bearing displacement in non-linear bearings

Hi,

I have created a model of a barrel vault (geometry + loads in Grasshopper). I encountered a problem while modeling the support displacements. The following boundary conditions apply:

The arch supports have a nonlinearity (failure in tension), so they can only transfer compressive forces.

When I apply the line displacement constraint (divided into x and z components according to the inclination of the supports), I get the error message that the line is not sufficiently supported.

My question is: How can I model a support displacement and, at the same time, a gap opening in the joint?

Wehrbau.rf6 (1.3 MB)

And one more question: I was told that it is possible to display the result distributions directly in the model – that would be great in my case, as it would allow me to estimate the compressive zone height directly! Does this option exist?

Thank you very much for answering!

Hi lennart,

To enter a forced displacement along a line, it is necessary that the line is supported in the direction of the forced displacement accordingly.

Please note: Nonlinearities in this direction are not supported and therefore cannot be used; more information: Line forced displacements in RFEM 6

:backhand_index_pointing_right: To display result distributions along lines, proceed as follows:

  1. Select line
  2. Click button Result distributions for selected lines

A detailed description can be found here: Result distributions in RFEM 6

Hello Marco,

Thanks a lot in advance. Again regarding the bearings: Do you have any idea how I can "bypass" the problem and both shift my bearing and represent the gap between the bearing and the first stone?

I appreciate any help :)
