Frequently Asked Questions (FAQ)

AnswerWhen 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.
