Additional Analysis 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.
