Design of Single, Bucket and Block Foundations

The RF-/FOUNDATION Pro add‑on module designs single, bucket and block foundations for all support forces arising in the RFEM/RSTAB model. The design of reinforced concrete foundations is performed according to:

EN 1992‑1‑1:2004 + A1:2014

The geotechnical designs are performed according to the standard:

EN 1997‑1

In addition to the support forces from RFEM/RSTAB, the module allows you to specify loads to be integrated into the design of a foundation. RF‑/FOUNDATION Pro provides a reinforcement concept for the upper and lower plate reinforcement, which is individually adjustable at any time.

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 concept for bottom and top reinforcement considering the most favorable combination of mat and rebars
- Individual adjustment of reinforcement concept
- Results of foundation reinforcement in detailed reinforcement drawings
- Results displayed in tables and graphics
- Visualization of foundation, columns and reinforcement in 3D rendering
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 quickly and easily define all other foundation details 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
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 manually edit the determined reinforcement. In this case, the designs are automatically updated.
Results
The program creates a reinforcement concept for the top and the bottom plate reinforcement by searching for the most favorable combination of a mat and added rebars. If required, the rebars are distributed across two reinforcement areas by curtailment. It is possible to individually modify the reinforcement concept:
- 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 on-site construction, the module provides solution proposal for bucket design. It is possible to modify number, position, diameter, and spacing of used rebars as well. You can also determine the shape of applied links.

Dimensions of foundation plate and bucket can be determined by the add-on module or user-defined. Clearly arranged windows display results of each performed design including all intermediate values. They are covered in a reduced printout report providing a verifiable structural analysis.
