KB 001623 | Nonlinear Calculation of a Floor Slab Made of Steel Fiber Reinforced Concrete in the Ultimate Limit State with RFEM
Video
First Steps with RFEM
Description
Steel fiber reinforced concrete is nowadays mainly used for industrial floors or hall floors, for foundation plates with low loads, basement walls and basement floors. Since the publication of the first guideline by the German Committee for Reinforced Concrete (DAfStb) about steel fiber reinforced concrete in 2010, the structural engineer can use standards for the design of the composite material steel fiber reinforced concrete, which makes the use of fiber reinforced concrete increasingly popular in construction. This article describes the nonlinear calculation of a foundation plate made of steel fiber reinforced concrete in the ultimate limit state with the FEA software RFEM.

General method for stability designs according to EN 1993-1-1 and buckling in the main bearing plane
In EN 1993-1-1, the General Method was introduced as a design format for stability designs, which can be used for planar systems with any boundary conditions and variable structural height.

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.

- How can I create a curved or arched section?
- 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 the message No. 47 in RFEM. What is the exact meaning of the word "integrate"? What is the resulting effect?
- How can I view the depth of the concrete compression zone in RF‑/CONCRETE?
-
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?
- How can I get the member end forces to design the connections?
