In RF-PUNCH Pro, you have different options to determine the punching loads on wall corners and wall ends on the basis of the RFEM surface internal forces.
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- Is it possible to apply the minimum bending moments according to DIN EN 1992‑1‑1 in RF‑PUNCH Pro?
- In RF‑PUNCH Pro, I get the message No. 58 saying that the surface load inside the critical perimeter cannot be determined for result combinations. Why is this message displayed? How can I avoid it?
- How is the collapse reinforcement considered in RF‑PUNCH Pro?
- Is the punching load in RF‑PUNCH Pro taken from the support forces of line supports in the case of the design on a wall corner? Which lengths are decisive for applying the support forces?
- In RF‑PUNCH Pro, the "1.4 Longitudinal Reinforcement" dialog box shows all surfaces connected to the nodes selected for design. So in the case of punching shear design on a wall corner, for example, it shows the surfaces that actually represent the walls. I can also define longitudinal reinforcement for these surfaces. Is this somehow recognized? Why do I see these surfaces in the dialog box 1.4?
- How is the minimum shear reinforcement according to DIN EN 1992‑1‑1 determined in RF‑PUNCH Pro?
- In RF-PUNCH Pro, I use the sector model to determine the load increasing factor ß. However, due to singularities in the surface internal forces, the ß-values are sometimes set too high. How can I handle this?
- When should the punching load be determined with the (un)smoothed distribution of the shear forces at the critical perimeter?
- I would like to perform the punching shear design on a column with connected downstand beams as a wall corner or Perform wall end. However, the module applies an internal column. Is it possible to adjust it?
- I am getting the message that my material does not meet the requirements of the current standard. How can I correct this?
