Automatic Calculation of Geometric Equivalent Imperfections

Automatic determination of geometric equivalent imperfections in RFEM and RSTAB.

Geometric equivalent imperfections are calculated automatically by determining the buckling mode using the Structure Stability add-on in RFEM and RSTAB. The calculated mode shapes form the basis for determining the imperfections. The initial bow can be specified as a relative value or according to EN 1993-1-1.
