Using Modified Stiffnesses for Dynamic Calculations
In RFEM, it is possible to modify stiffnesses for materials, cross -sections, members, load cases, and load combinations in many places.

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.
- In connection with the analytical SLS calculation, I get implausibly large values for the crack width and deformation in the RF‑CONCRETE add-on modules. What is the cause and how can I fix the problem?
- Is it possible to export the results from RF‑CONCRETE Surfaces to Excel? For example, I would need the steel stress of serviceability design.
- Is it possible to adjust the initial values of the temperature courses entered for the fire resistance design? For example, I would like to adjust the initial value of the moisture content.
- How can I change the size of reinforcement bars from the American code (#3,#4, and so on) to millimeters in RF‑CONCRETE Members while using ACI?
- Is it possible in RF‑CONCRETE Surfaces to model a prefabricated slab or an element slab with different reinforcement layouts, for example, a reinforcement layer in a precast element and another reinforcement layer in the cast-in-place concrete extension?
- How do you perform the fatigue design for reinforced concrete and prestressed concrete? I have found a result combination of the type fatigue, but cannot find the design in the add-on modules.
- How can I create a curved or arched section?
- How are the signs for the release results of a line release and line hinges interpreted?
- Is it possible to manually specify a longitudinal reinforcement for design in RF‑PUNCH Pro?
- Can I simulate the cracked state of a concrete cross -section for a bending beam with the "Isotropic Nonlinear Elastic 1D" material model?
