All Add-ons for RFEM 6

The "Nonlinear Material Behavior" add-on allows you to take material nonlinearities in RFEM into account. If you use nonlinear material models in RFEM, the program always performs an iterative calculation. Depending on the material model, it defines a different relationship between stresses and strains. The stiffness of the finite elements is repeatedly adjusted during the iterations until the stress-strain relationship is complied with.

The Structure Stability add-on performs stability analysis of structures. It determines critical load factors and the corresponding stability modes.

The Construction Stages Analysis (CSA) add-on allows for considering the construction process of structures (member, surface, and solid structures) in RFEM.

The Time-Dependent Analysis (TDA) add-on allows you to consider the time-dependent material behavior of members and surfaces. The long-term effects, such as creep, shrinkage, and aging, can influence the distribution of internal forces, depending on the structure.

The form-finding add-on determines the optimal shape of axially loaded members (cables) and tension-loaded surface models (membrane structures).

The Torsional Warping (7 DOF) add-on allows you to consider cross-section warping as an additional degree of freedom.

In RFEM, the Geotechnical Analysis add-on uses the properties from soil samples to determine a soil body to be analyzed.

The Modal Analysis add-on allows for the calculation of eigenvalues, natural frequencies, and natural periods for member, surface, and solid models.

The Response Spectrum Analysis add-on performs seismic analysis using multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or can be user-defined. The equivalent static forces are generated from them. The add-on includes an extensive library of accelerograms from seismic zones that can be used to generate the response spectra.

The Time History Analysis add-on supports dynamic structural analyzes with external excitations, where the excitation functions can be defined as time functions or accelerogram.

Using the Pushover Analysis add-on, you can analyze the seismic actions on a particular building, and thus assess whether the building can withstand an earthquake.

The add-on uses particle swarm optimization (PSO) to determine optimal parameters for parameterized models based on weight, cost, or CO₂ emissions.

The "Building Model" add-on simplifies the modeling and analysis of reinforced concrete buildings. It expedites the creation of building models and automates load generation, making it ideal for demanding reinforced concrete projects.

The Multilayer Surfaces add-on allows you to define multilayer surface structures. The calculation can be carried out with or without the shear coupling.

The Stress-Strain Analysis add-on performs general stress analysis by calculating the existing stresses and comparing them with the limit stresses.

The Concrete Design add-on allows for various design checks according to international standards. You can design members, surfaces, and columns, as well as perform punching and deformation analyses.

The Steel Design add-on performs the ultimate and serviceability limit state design checks of steel members according to various standards.

The Timber Design add-on performs the ultimate, serviceability, and fire resistance limit state design checks of timber members according to various standards.

The Masonry Design add-on uses the finite element method and an elastic-plastic material model specially developed for masonry for the design.

The Aluminum Design add-on performs the ultimate and serviceability limit state design checks of aluminum members according to various standards.

The Concrete Foundations add-on for RFEM 6 allows you to calculate and design reinforced and unreinforced foundation plates as well as bucket and block foundations.

This powerful tool simplifies the dimensioning of glass structures, from single panels to complex laminated systems, ensuring you can tackle any design challenge with ease.

The "Tendons" add-on enables realistic modeling of prestressed and post-tensioned tendons. With flexible 3D geometry definition and full integration into FEM analysis, it provides an accurate and efficient solution for demanding concrete structures.

The Steel Joints add-on for RFEM allows you to analyze steel connections using an FE model. The FE model is generated automatically in the background and can be controlled via the simple and familiar input of components.

The “Cutting Pattern” add-on was developed to divide multiaxially curved net surface geometries into production-ready, planar part segments. This program is typically used to process data from a form-finding analysis performed by the Form-Finding add-on.
