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.
In this tutorial, we would like to inform you about the essential features of the RFEM program.

The US codes are used as standards.
The Stress-Strain Analysis add-on performs a general stress analysis by calculating the existing stresses and comparing them with the limit stresses. Strains for surfaces and solids can also be determined.
During the stress analysis, the maximum stresses of solids, surfaces, and line welds (RFEM only), as well as members are determined. The governing internal forces are also documented for each member and each surface. Furthermore, there is the option of an automatic section or thickness optimization including the update of the sections or surface thicknesses modified in RFEM/RSTAB.
This manual describes the Stress-Strain Analysis add-on for the programs RFEM 6 and RSTAB 9.
Dynamic analyses in RFEM 6 and RSTAB 9 can be performed in several add-ons.
- The Modal Analysis add-on is the basic add-on, performing natural vibration analyses for member, surface, and solid models. It is a prerequisite for all other dynamic add-ons.
- The Response Spectrum Analysis add-on allows you to perform a seismic analysis using the multi-modal response spectrum analysis.
- The Time History Analysis add-on allows for a dynamic structural analysis of external excitations that can be defined as a function of time.
- The Pushover Analysis add-on allows you to determine the maximum nonlinear response of a structure to seismic loads.
- The Harmonic Response Analysis add-on is still under development.
This manual describes the dynamic analysis add-ons for RFEM 6 and RSTAB 9.
The Timber Design add-on allows you to design timber members and surfaces according to various design standards. Cross-section resistance checks, stability analyses, and serviceability limit state design checks can also be performed. 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 Timber Design add-on for the RFEM 6 and RSTAB 9 programs.
The Aluminum Design add-on allows you to design aluminum members according to various design standards. It is possible to perform cross-section resistance checks, stability analyses, and serviceability limit state design checks. 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 Aluminum Design add-on for the RFEM 6 and RSTAB 9 programs.
The "Steel Joints" add-on allows for the analysis of connections on the basis of an FE model. The design checks are carried out for various connection types for rolled and welded cross-sections. The input and result evaluation are completely integrated in the user interface of the structural FEA software RFEM.
This manual describes the Steel Joints add-on for RFEM 6.
In this tutorial, we would like to inform you about the essential features of the RFEM program. In the first part, a model was defined and a structural analysis carried out. Then the concrete and steel designs were performed in the following parts. This part now deals with the design of the steel connections according to EN 1993-1-8 with the CEN settings.
The Construction Stages Analysis (CSA) add-on allows you to represent the construction process of the model in the RFEM 6 program. In this way, you can add, remove, or adjust structural objects to the individual construction phases. Furthermore, you can use the add-on can to determine the sequence of the load application and the way how the load cases are combined within the construction stages.
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.
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 Modeling and Design of Timber Structures in RFEM 6.
First, it shows how to model a hip rafter in RFEM 6 and how to apply loads, as well as how to perform timber design according to Eurocode 5. The creation of a printout report and the use of parameters and user-defined scripts are then discussed.
In the manual for the Timber Design add-on, you can find detailed explanations of all the add-on options.
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.
This manual describes the topics of the webinar "Modeling and Design of Solid Elements in RFEM 6".
In the webinar, a splice with bolts is modeled. It explains how you can define the contact between solids and perform a stress-strain analysis. Furthermore, the utilization of welds is also considered.
In this tutorial, we would like to inform you about the essential features of the RFEM program. In the first part, a model was defined and a structural analysis carried out. Then the concrete and steel designs were performed out in the following parts. This part now guides you through the dynamic analysis of the model according to EN 1998-1 with the CEN settings.
