In RFEM, it is possible to modify stiffnesses for materials, cross -sections, members, load cases, and load combinations in many places.
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.
- When I create a user-defined result value, the RFEM solver window opens briefly and the calculation is apparently performed again. Why? I have already performed the calculation before.
- 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?
- Why is the deflection of the reinforced concrete floor sometimes greater when selecting a larger basic reinforcement?
- I have a question about message no.47 in the RFEM program. 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 get the value X as additionally required reinforcement. If I enter this value X as the existing 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?
- How can I get the member end forces to design the connections?
