  1. Consideration of Effects From Second Order Theory

    In RFEM and RSTAB, the internal forces of individual load combinations are determined according to the second‑order analysis by default. If you use the RF‑CONCRETE add‑on module for stability analysis of reinforced concrete columns, you can change the calculation method of LCs to the linear static analysis, since the effects of the second‑order analysis are already considered in the calculation according to the model column method in RF‑CONCRETE Columns (nominal curvature method).

  2. Considering Imperfections

    In the world of construction engineering, the word “imperfections” has a specific meaning. It describes the imperfections of a structure or the deviation of a structural component from its ideal form due to manufacturing.
