Longitudinal Reinforcement
Glossary Term
Concrete components can be reinforced and unreinforced. If the reinforcement is required, it may consist of members or mats. The reinforcement is generally used to make the component more resistant, since concrete can only absorb very limited tensile forces.
The main purpose of the longitudinal reinforcement (also called main reinforcement) is the absorption of bending tensile stresses in the longitudinal direction of the main support direction of the structural component. The cross-section of the reinforcement steel ensures that the tensile forces due to bending are absorbed with or without the longitudinal force and possibly torsion.
The longitudinal reinforcement is placed on the top and bottom sides of the plates or downstand beams. For columns, the symmetrical or radial arrangement is the rule.

If the geometry of a surface, for which you must remove some of the existing boundary lines, changes subsequently, you don't need to redefine the surface.

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.

-
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?
- How can I perform the design of the tension resistance of a smooth column in a smooth bucket column base, that is, the design against pulling out the column?
