In addition to the National Annexes (NA) listed above, you can also define a specific NA, applying user‑defined limit values and parameters.
- Automatic calculation of governing loading from load cases
- Specification of additional support forces
- Determination of the reinforcement proposal for the bottom and top plate reinforcement considering the most favorable combination of mat and rebars
- Individual adjustment of reinforcement proposal
- Results of foundation reinforcement in detailed reinforcement drawings
- Results displayed in tables and graphics
- Visualization of foundation, columns, and reinforcement in 3D rendering
RF-/FOUNDATION Pro | Input
Foundations are assigned graphically by selecting supports using the [Select] function in the graphical user interface of RFEM/RSTAB and by specifying the load cases to be designed. You can define all other foundation details quickly and easily in clearly arranged input windows.
In addition to all support forces from RFEM/RSTAB, you can specify further loads to be considered when dimensioning the foundations. The following additional loadings are available:
- Pemanent surface load due to earth covering
- Negative surface load; for example, due to traffic
- Ground water level for uplift consideration
- Concentrated loads in any position on the foundation plate
- Line loads with any distribution over the foundation plate
RF-/FOUNDATION Pro | Design
It is possible to perform the following designs:
- Equilibrium limit state design
- Uplift limit state design
- Ground failure (soil contact pressure) design
- Strong eccentric loads design
- Design of foundation torsion and limitation of gaping joint
- Sliding design
- Settlement calculation
- Bending failure design of the plate and bucket
- Punching shear design
Foundation and bucket dimensions can be user-defined or determined by the module. You can edit the determined reinforcement manually. In this case, the designs are updated automatically.
RF-/FOUNDATION Pro | Results
The program creates a reinforcement proposal for the top and the bottom plate reinforcement. The program searches automatically for the most favorable reinforcement combination, with a mat and added rebars. If required, the rebars are distributed across two reinforcement areas by curtailment. It is possible to modify the reinforcement proposal individually by:
- Application of another mat type
- Individual control of diameter and spacing of added rebars
- Free selection of reinforcement area widths
- Individual curtailment of reinforcements
You can display the foundation in excellent rendering quality, including reinforcement. In the rendering, as well as in up to seven different dimensioned reinforcement drawings ready for construction, the module provides a solution proposal for bucket design. It is possible to modify the number, position, diameter, and spacing of used rebars here as well. You can also determine the shape of the applied links.
The dimensions of the foundation plate and bucket can be determined by the add-on module, or can be user-defined. Clearly arranged windows display the results of each performed design, including all intermediate values. They are covered in a reduced printout report providing a verifiable structural analysis.
