RF-CONCRETE NL Add-on Module for RFEM | Nonlinear reinforced concrete calculation for the serviceability limit state
Window "1.1 General Data" for Serviceability Limit State with Settings for Nonlinear Calculation According to 
- When converting from the manual definition of reinforcement areas to the automatic arrangement of reinforcement according to Window 1.4, the result of the deformation calculation differs, although the basic reinforcement has not been modified. What is the reason for this change?
- I obtain different results when comparing the deformation analysis in the RF‑CONCRETE add-on modules and another calculation program. What could be the reason for this?
- What information is transferred when exporting the nonlinear stiffness? Can I display the exported values graphically?
- Is it also possible to perform a deformation analysis in cracked state for a 2D model in RF‑CONCRETE Surfaces?
- I have a roof structure resting on a steel column that runs to the foundations. The column runs through a perimeter wall that supports the false ceiling. A considerable part of the load from the roof is transferred to the wall. I want the steel column to carry all the vertical loads from the roof. How can I do it?
- Are the models and presentations from Info Day 2018 freely available, and can you send them to me?
- In RF‑CONCRETE Surfaces, I obtain a high amount of reinforcement in relation to a lever arm that is almost zero. How is such a small lever arm of internal forces created?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
- Does the program check the lap length of the vertical stirrups of a block foundation with smooth bucket sides?
- Why do I get a discontinuous area in the distribution of internal forces? In the area of the supported line, the shear force VEd shows a jump, which does not seems to be plausible.
