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 Masonry Design add-on activates special material models that have been developed for calculating masonry structures. This allows you to consider the masonry material in an FEM analysis.
In the calculation, internal forces and deformations are determined on the basis of stress-strain lines derived from the standardization. This means that the design is based on the standard.
This manual describes the Masonry Design add-on for the RFEM 6 program.
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.
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.

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 AISC 360-22.
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.
The Multilayer Surfaces Add-on allows you to define the layer structure of any material models. In the case of orthotropic materials, the individual layers can be rotated by an angle β, and thus it is possible to consider different stiffnesses by direction. The Multilayer Surfaces add-on is completely integrated in the user interface of the FEA program RFEM.
This manual describes the Multilayer Surfaces add-on for the RFEM 6 program.
