In this tutorial, we would like to inform you about the essential features of the RFEM program. The first part shows how to create the structural objects and loads, combine the loads, perform a structural analysis, check the results, and prepare the data for printing. Eurocodes with the CEN settings are used as standards.

The Form-Finding add-on finds the optimal shape of members subjected to axial forces and tension-loaded surface models. The shape is determined by the equilibrium between the member axial force or the membrane stress and the existing boundary conditions.
The resulting new model shape with impressed force conditions is made available as a universally applicable initial state for further calculation of the entire structure.
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 modeling of a stadium roof made of membranes in RFEM 6. Since the model consists of several segments, the creation of the individual segments is shown. Each segment consists of a main structure (a column, a stiffening element, cables) and a secondary structure (a membrane).
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.
