Question

What information is transferred when exporting the nonlinear stiffness? Can I display the exported values graphically?


Answer:
When exporting the nonlinear stiffness from the RF‑CONCRETE Members add-on module or from the RF‑CONCRETE Surfaces add-on module, only the stiffness values are exported.

The following results or effects are not exported:

  • Shrinkage: The influence of shrinkage is not exported directly because the shrinkage referring to the load side and not to the stiffness side is considered. If a change in stiffness (cracking) occurs when considering the shrinkage, the effect is exported, of course.
  • Results from the NL calculation: Further results from the nonlinear calculation, such as crack width or steel and concrete stress, are not exported.
It is currently not possible to display the exported stiffness graphically in RFEM.
