The Nonlinear Material Behavior add-on allows you to consider material nonlinearities in RFEM (e.g. isotropic plastic, orthotropic plastic, isotropic damage).
The Structure Stability add-on analyzes the stability of structures. It determines critical load factors and the corresponding stability modes.
With the Construction Stages Analysis (CSA) add-on, the construction process of structures (member, surface, and solid structures) can be considered in RFEM.
Neglecting the influence of the construction process can lead to errors in the calculation of overall models. With the Construction Stages Analysis (CSA) add-on, you can analyze these influences and consider them up to the point of the structural design.
Time-Dependent Analysis (TDA) add-on allows you to consider time-dependent material behavior of members. 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 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 Torsional Warping (7 DOF) add-on allows you to consider the cross-section warping as an additional degree of freedom when calculating members in RFEM and RSTAB.
In RFEM, the Geotechnical Analysis add-on uses the properties from soil samples to determine the soil body to be analyzed. The realistic determination of the soil conditions significantly influences the quality of the structural analysis of buildings.
