Material Model Orthotropic Masonry 2D
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.
The total strain tensor 𝜺 is additively divided into the elastic and inelastic parts 𝜺 = 𝜺el + 𝜺p. It is assumed that the damage follows a smeared crack if the material remains a continuum even after the damage.
To use the material model Orthotropic Masonry 2D, the RF-MAT NL add-on module is required.
In RFEM, it is possible to modify stiffnesses for materials, cross -sections, members, load cases, and load combinations in many places.

- I have a question about the message No. 47 in RFEM. What is the exact meaning of the word "integrate"? What is the resulting effect?
If I do not specify any basic reinforcement in RF‑CONCRETE Surfaces, I obtain the value X as an additionally required reinforcement. If I enter this value X as the provided basic reinforcement, I correctly do not get any additional required reinforcement.
However, if I enter a lower value than the determined required total reinforcement as the basic reinforcement, the additionally required reinforcement is increased in such a way that the originally required reinforcement content is exceeded. Why?
- Why does the RF‑CONCRETE Surfaces add-on module not increase the amount of reinforcement until the SLS designs have a design ratio of 1.0?
