Database of Foundation Templates
In RFEM 5 as well as RSTAB 8 in RF-/FOUNDATION Pro, you can save the foundation dimensions for all five foundation types as foundation templates in a user-defined database and use them later in other models.
Separate Load Entry for Structure or Foundation Design
In RF-/FOUNDATION Pro, the foundation design requires the definition of the corresponding loading (load cases, load combinations, or result combinations) for different design situations (STR, GEO, UPL, or EQU).
Factor for Taking into Account Unloading of Soil Pressure
In RF-/FOUNDATION Pro, the user can freely select the proportion of the relieving soil pressure by means of the factor kred.
Displaying Specific Results
In RF‑/FOUNDATION Pro, you now have the option to design a foundation at one or several nodes of the model.

Product Features
Material model Anisotropic | Damage, nonlinear behavior, concrete and reinforced concrete

The "Nonlinear Material Behavior" add-on includes the Anistropic | Damage material model for concrete structural components. This material model allows you to consider concrete damage for members, surfaces, and solids.

You can define an individual stress-strain diagram via a table, use the parametric input to generate the stress-strain diagram, or use the predefined parameters from the standards. Furthermore, it is possible to consider the tension stiffening effect.

For the reinforcement, both nonlinear material models "Isotropic | Plastic (Members)" and "Isotropic | Nonlinear Elastic (Members)" are available.

It is possible to consider the long-term effects due to creep and shrinkage using the "Static Analysis | Creep & Shrinkage (Linear)" analysis type that has been recently released. Creep is taken into account by stretching the stress-strain diagram of the concrete using the factor (1+phi), and shrinkage is taken into account as the pre-strain of the concrete. More detailed time step analyses are possible using the "Time-Dependent Analysis (TDA)" add-on.

Feature 002918 | Determination of Required Longitudinal Reinforcement for Direct Crack Analysis

In the Concrete Design add-on, you can determine the required longitudinal reinforcement for the direct crack width analysis (w k).

Feature 002920 | Automatic Function of Longitudinal Reinforcement for Members

For the design of reinforced concrete members, there is the option to automatically determine the number or diameter of rebars.

Feature 002916 | Joint-Structure Interaction for Steel Joints

Want to automatically consider steel joint stiffness in your global RFEM model? Utilize the Steel Joints add-on!

Activate joint-structure interaction in the stiffness analysis of your steel joints. Hinges with springs are then automatically generated in the global model and included in subsequent calculations.

Frequently Asked Questions (FAQ)
Are the models and presentations from Info Day 2018 freely available, and can you send them to me?
How can I display the internal forces in the global coordinate system and not in the principal coordinate system of the cross-section?
I want to create a mapped mesh for a circular hole plate. Is it possible to generate such a meshing in RFEM?
Is it possible to divide a free surface load by the existing lines in RFEM?
How do I display some results of all load cases in the printout report but other results of selected load cases only?
RF‑STEEL AISC add-module shows non-designable results for general cross-sections because of shear buckling checks according to Chapter G. How do I solve this?
