Additional Analysis for RFEM 6

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.

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.
