Nonlinear Material Behavior
The Nonlinear Material Behavior add-on allows you to consider material nonlinearities in RFEM. If you use nonlinear material models in RFEM, the program always performs an iterative calculation. Depending on the material model, it defines a different relation between the stresses and strains. The stiffness of the finite elements is adjusted again and again in the course of the iterations until the stress-strain relation is met.
Construction Stages
The Construction Stages Analysis (CSA) add-on allows for considering the construction process of structures (member, surface, and solid structures) in RFEM.
Lateral-Torsional Buckling with Warping Torsion
The Torsional Warping (7 DOF) add-on allows you to consider cross-section warping as an additional degree of freedom.
Geotechnical Analysis
In RFEM, the Geotechnical Analysis add-on uses properties from soil samples to determine the soil body to be analyzed. The accurate determination of soil conditions significantly affects the quality of the structural analysis of buildings.
Response Spectrum Analysis
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.
Optimization of Model Parameters
The add-on uses particle swarm optimization (PSO) to determine optimal parameters for parameterized models based on weight, cost, or CO2 emissions.

Definition of Multilayer Surfaces, such as Laminate Surfaces or Cross-Laminated Timber (CLT)
The Multilayer Surfaces add-on allows you to define multilayer surface structures. The calculation can be carried out with or without the shear coupling.
