Nonlinear Material Behavior for RFEM 6

The Nonlinear Material Behavior add-on for RFEM 6 allows you to consider nonlinear material behavior in RFEM (for example, isotropic plastic, orthotropic plastic, isotropic damage).

Structure Stability for RFEM 6 / RSTAB 9

The Structure Stability add-on allows you to carry out stability analyses. It determines critical load factors and the corresponding stability modes – making your work significantly easier, if you deal with this area.

Construction Stages Analysis (CSA) for RFEM 6

Have you already heard of the Construction Stages Analysis (CSA) add-on? It allows you to consider the construction process of structures (member, surface, and solid structures) in RFEM.

If the influence of the construction process is neglected, errors may arise in the calculation of entire models. You can avoid this problem by using the Construction Stages Analysis (CSA) add-on. Use it to analyze the influences with minimum effort and consider them right up to the structural design.

Time-Dependent Analysis (TDA) for RFEM 6

The ravages of time gnaw at every building and is often difficult to estimate. The Time-Dependent Analysis (TDA) add-on allows you to consider the time-dependent material behavior of members. Long-term effects, such as creep, shrinkage, and aging, can influence the distribution of internal forces, depending on the structure. Use this add-on, to take such effects into account.

Form-Finding for RFEM 6

Does form-finding mean anything to you? If it's an important part of your job, you've come to the right place. The Form-Finding add-on searches for the optimal shape of members subjected to axial forces and surface models subjected to tension. The shape is determined by the equilibrium between the member axial force or the membrane stress and the existing boundary conditions.

Torsional Warping (7 DOF) for RFEM 6 / RSTAB 9

The Torsional Warping (7 DOF) add-on expands your options in RFEM and RSTAB. It allows you to consider cross-section warping as an additional degree of freedom when calculating members.

Geotechnical Analysis for RFEM 6

The Geotechnical Analysis add-on is a useful addition for working on your project. In RFEM, it uses the properties from soil samples to determine the soil body to be analyzed. This is of particular importance for your project. For a realistic determination of the soil conditions significantly influences the quality of your structural analysis of buildings.
