The Torsional Warping (7 DOF) add-on allows you to consider the cross-section warping as an additional degree of freedom for a global calculation of members in RFEM and RSTAB. The input and result evaluation are completely integrated in the user interface of the structural FEA software RFEM and the frame & truss analysis software RSTAB.
This manual describes the Torsional Warping (7 DOF) add-on for the programs RFEM 6 and RSTAB 9.
This manual describes the topics of the webinar "Stability and Warping Torsion Analyses in RFEM 6 and RSTAB 9".
In the webinar, a stability analysis of a staircase tower is carried out. It explains when and why a warping torsion analysis with 7 degrees of freedom is necessary. Furthermore, special attention is given to how you can create and combine local imperfections in RFEM 6 and RSTAB 9.
In the manual, all steps are carried out in RFEM 6, but the same also applies to RSTAB 9.
