Add-on Modules RF-CONCRETE RF-CONCRETE NL

To what extent does RFEM consider the inserted reinforcement in the determination of the stress or internal forces? Is the entered reinforcement only taken into account by the additional module RF-CONCRETE Surfaces?

Answer

When determining area tensions or section sizes in RFEM, the entered reinforcement is initially ignored.
RFEM uses an isotropic linear-elastic material model.

Optionally, you can use the RF-CONCRETE NL module to carry out a non-linear design in the serviceability limit state in the RF-CONCRETE Surfaces module. Here you can define an existing reinforcement before dimensioning.
The module determines a non-linear stiffness taking into account the inserted reinforcement and the cracked state.

You can then optionally export this non-linear stiffness to RFEM and activate it for the recalculation of the surface intersections for individual load cases and load combinations.
