Generally, buildings are not constructed in one go, but in stages. From a structural point of view, the individual structural parts are combined into a building during the construction. At the latest upon completion of the construction process, the structure designed for the final state is available. Before reaching the final state, the structure is going through the various construction stages.

The new generation of 3D FEA software is used for the structural analysis of members, surfaces, and solids.

The Aluminum Design add-on performs the ultimate and serviceability limit state design checks of aluminum members according to various standards.

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 Stress-Strain Analysis add-on performs general stress analysis by calculating the existing stresses and comparing them with the limit stresses.

The Torsional Warping (7 DOF) add-on allows you to consider cross-section warping as an additional degree of freedom.

The Steel Joints add-on for RFEM allows you to analyze steel connections using an FE model. The FE model is generated automatically in the background and can be controlled via the simple and familiar input of components.

The Steel Design add-on performs the ultimate and serviceability limit state design checks of steel members according to various standards.

The modern 3D structural analysis and design program is suitable for the structural and dynamic analysis of beam structures as well as the design of concrete, steel, timber, and other materials.

The Structure Stability add-on performs the stability analysis of structures. It determines critical load factors and the corresponding stability modes.

The Stress-Strain Analysis add-on performs a general stress analysis by calculating the existing stresses and comparing them to the limit stresses.

The Steel Design add-on performs the ultimate and serviceability limit state design checks of steel members according to various standards.

The Aluminum Design add-on performs the ultimate and serviceability limit state design checks of aluminum members according to various standards.
