Working with RF-/STEEL AS
First, you need to select load cases, load combinations, and result combinations for design.
In the next input windows, you can adjust preset definitions of lateral intermediate supports, buckling lengths, and other standard-specific design parameters. In the case of continuous members, it is possible to define individual support conditions and eccentricities for each intermediate node of single members. A special FEA tool determines critical loads and moments required for the stability analysis.
In connection with RFEM/RSTAB, it is possible to apply the Direct Analysis Method considering the influence of the general calculation according to the second-order analysis. This method allows you to avoid using special enlargement factors.
