RFEM 5 Add-on Module
RF-CONCRETE

The RF‑CONCRETE add-on module performs the required ultimate and serviceability limit state design checks of reinforced concrete members and surfaces. Moreover, it is possible to perform the fire resistance design for rectangular and circular cross-sections.

The add-on module provides detailed design options, an integrated graphical output of the results, and a clear numerical result output. Additional features include fire resistance design and the option to optimize cross-sections.

Flexibility due to detailed setting options for basis and extent of calculations
Fast and clear results output for an immediate overview of the result distribution after the design
Graphical results output integrated in RFEM; for example, required reinforcement
Numerical results clearly arranged in tables and graphical display of the results in the model

Features of RF-CONCRETE Members

Determination of longitudinal, shear, and torsional reinforcement
Representation of minimum and compression reinforcement
Determination of neutral axis depth, concrete and steel strains
Design of member sections affected by bending about two axes
Design of tapered members
Determination of deformation in state II, for example according to EN 1992-1-1, 7.4.3
Considering tension stiffening
Considering creep and shrinkage
Precise breakdown of reasons for failed design
Design details of all design locations for better traceability of reinforcement determination
Options to optimize cross‑sections
Visualization of concrete section with reinforcement in 3D rendering
Output of complete steel schedule
Fire resistance design according to the simplified method (zone method) according to EN 1992‑1‑2 for rectangular and circular cross‑sections
Optional extension of the RF‑CONCRETE Members add‑on module with a nonlinear calculation of frameworks for the ultimate and serviceability limit states. The extension enables the design of potentially unstable structural components by means of a nonlinear calculation, or a nonlinear deformation analysis of 3D frameworks. Find more information under the product description of the RF-CONCRETE NL add‑on module.

Features of RF-CONCRETE Surfaces

Free definition of two or three reinforcement layers in the ultimate limit state
Vectorial representation of the main stress directions of internal forces allowing optimal orientation adjustment of the third reinforcement layer to the actions
Design alternatives to avoid compression or shear reinforcement
Design of surfaces as deep beams (theory of membranes)
Option to define basic reinforcements for top and bottom reinforcement layers
Definition of designed reinforcement for serviceability limit state design
Result output in points of any selected grid
Optional extension of the module with nonlinear deformation analysis. The calculation is performed in RF‑CONCRETE Deflect by reducing the stiffness according to the standard, or in RF‑CONCRETE NL by the general nonlinear calculation determining the stiffness reduction in an iterative process.
Design with design moments at column edges
Precise breakdown of reasons for failed design
Design details of all design locations for better traceability of reinforcement determination
Export of isolines for the longitudinal reinforcement in a DXF file for further use in CAD programs as a basis for reinforcement drawings

RF-CONCRETE | Input

In order to facilitate the data input, surfaces, members, sets of members, materials, surface thicknesses, and cross-sections are preset in RFEM. It is possible to select the elements graphically using the [Select] function. The program provides access to the global material and section libraries. Load cases, load combinations, and result combinations can be combined in various design cases. You can enter all geometric and standard-specific reinforcement settings for the reinforced concrete design in a segmented window. The geometry entries in both RF‑CONCRETE modules differ from each other.

In the RF-CONCRETE Members add-on module, for example, This includes, for example, specifications for the curtailment of rebars, number of layers, cutting ability of links, and anchorage type. For the fire resistance design of reinforced concrete members, you have to define the fire resistance class, the fire‑related material properties, and the cross‑section sides exposed to fire.
In the RF‑CONCRETE Surfaces add‑on module, it is necessary to specify, for example, the concrete cover, the reinforcement direction, the minimum and the maximum reinforcement, the basic reinforcement to be applied, or the designed longitudinal reinforcement, as well as the rebar diameter.

Surfaces or members can be summarized in special "reinforcement groups", each defined by different design parameters. This way, it is possible to efficiently calculate alternative designs with different boundary conditions or modified cross‑sections.

RF-CONCRETE Surfaces - Graphical Results Output for Complete Structural Model

RF-CONCRETE | Results

After the calculation, the module shows clearly arranged tables listing the required reinforcement and the results of the serviceability limit state design. All intermediate values are included in a comprehensible manner.

The results of RF‑CONCRETE Members are displayed as result diagrams of each member. The reinforcement proposals of the longitudinal and the shear reinforcement, including sketches, are documented in accordance with current practice. It is possible to edit the reinforcement proposal and to adjust, for example, the number of members and the anchorage. The modifications will be updated automatically. A concrete cross‑section, including reinforcement, can be visualized in a 3D rendering. This way, the program provides an optimal documentation option to create reinforcement drawings, including steel schedule.

The results of RF-CONCRETE Surfaces can be displayed graphically as isolines, isosurfaces, or numeric values. It is possible to sort the longitudinal reinforcement display by required reinforcement, required additional reinforcement, provided basic or additional reinforcement, and provided total reinforcement. The isolines of the longitudinal reinforcement can be exported as a DXF file for further use in CAD programs as a basis for reinforcement drawings.
