Deactivation of Nonlinear Effects
If nonlinear effects are used in the model, it is possible to deactivate them in the global calculation parameters.

Depending on stiffness, mass, and damping, structures react differently to wind action.
- How can I incrementally apply the load of a load case to the model?
- After importing an .stp file, my model is unstable. What can be the reason for this?
- Are the models and presentations from Info Day 2017 freely available, and can you send them to me?
- Can I define nonlinear supports by using tables?
- In the case of a nonlinear calculation for the serviceability limit state designs, I get implausibly large values for the crack width and deformation in the RF‑CONCRETE modules (see Figure 01). What is the cause and how can I fix the problem?
- Is it also possible to use nonlinear material behavior in a time history analysis?
- In a nonlinear structural system, some load cases do not converge. However, load combinations can be calculated without any problems. What could be the reason for this?
- I obtain different results when comparing the deformation analysis in the RF‑CONCRETE add-on modules and another calculation program. What could be the reason for this?
- I would like to define a line support with ineffective tension and apply the tension force on this line by using a nodal support instead. Why does the line support still receive a tension force?
- There are two different add-on modules for a response spectrum analysis in RF‑/DYNAM Pro. What can be the reasons for the different results of both add-on modules?
