Concrete
Glossary Term

By adding concrete admixtures and additives to a concrete mixture, the workability and other concrete properties can be influenced.
The concrete building material is processed after mixing in the 'liquid' state and can take any shape by using a concrete formwork. This is referred to as the installation of fresh concrete, which consists of liquid cement paste and solid aggregate particles. In the course of concrete hardening, most of the water contained is chemically bonded. The result is a solid building material, which is also known as artificial stone.
The concrete classification is based on the dry hardened density of the concrete:
- Lightweight concrete γ < 2,000 kg/m3
- Normal concrete 2,000 kg/m3 < γ < 2,600 kg/m3
- Heavy concrete γ > 2,600 kg/m3

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.
Frequently Asked Questions (FAQ)
- How are the signs for the release results of a line release and line hinges interpreted?
- 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?
