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.
The Concrete Design add-on allows you to design reinforced concrete members and surfaces according to various design standards. It is possible to perform the ultimate limit state 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 Concrete Design add-on for RFEM 6 and RSTAB 9. In RSTAB, you can only design members and member sets, not surfaces.
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 was carried out. The second part deals with the concrete design of the slabs, walls, beams, and the column according to EN 1992‑1‑1 with the CEN settings.
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 was carried out. Now, the second part deals with the concrete design of slabs, walls, beams, and the column. ACI 318-19 is used as a standard.
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.

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.
For some structures, the long-term effects, such as creep, shrinkage, and aging, can influence the distribution of internal forces. This time-dependent material behavior can be determined using the Time-Dependent Analysis (TDA) add-on, which is available in the RFEM 6 program.
The influence of the time-dependent material behavior is currently only taken into account for member elements, and creep effects for the material concrete.
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 Building Model add-on allows you to define and manipulate a building by means of stories. The stories can be adjusted in many ways. Information about the stories and also the entire model (a center of gravity) is displayed in tables and graphics.
This manual describes the Building Model add-on for the RFEM 6 program.
The Geotechnical Analysis add-on allows for a finite element analysis of soil solids with the suitable material laws in RFEM 6. By integrating Geotechnical Analysis into the FEA software, the soil-structure interaction can be represented computationally completely in the overall model.
With the Geotechnical Analysis, it is possible to determine the stresses and deformations of a soil solid. The input and result evaluation are integrated in the user interface of the RFEM 6 program.
This manual describes the Geotechnical Analysis add-on for the RFEM 6 program.
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 Reinforced Concrete Structures in RFEM 6 and RSTAB 9".
Using an example of a building ceiling, we explain how to perform reinforced concrete design according to Eurocode 2. Furthermore, the result documentation in the printout report is explained.
In the manual for the Concrete Design add-on, you can find detailed explanations of all the add-on options.
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.
