Supports contributing to a load reduction only under compression or tension can be defined as nonlinear supports in RFEM and RSTAB. It is not always easy for the user to select the correct nonlinearity for "failure under tension" or "failure under compression".
Structures react differently to wind action depending on stiffness, mass, and damping.
- How does the "Orthotropic Plastic" material model work in RFEM?
- 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?
- 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?
- 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?
- 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?
