In addition to the National Annexes (NA) listed above, you can also define a specific NA, applying user‑defined limit values and parameters.

• Flexibility due to detailed setting options for basis and extent of calculations
• Quick and clear results output for an overview of the distribution of results immediately subsequent to the design
• Graphical results output integrated in RFEM; for example, required reinforcement
• Clearly arranged numerical results output displayed in tables and option to represent results graphically in the model
• Complete integration of data output in the RFEM printout report

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 cross-sections affected by bending about two axes
• Design of tapered members
• Determination of deformation in cracked sections (state II), for example according to EN 1992-1-1, 7.4.3
• Consideration of tension stiffening
• Consideration of creep and shrinkage
• Itemization of reasons for failed design
• Design details for all design locations for better traceability of reinforcement determination
• Options to optimize cross‑sections
• Visualization of concrete cross‑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

Freely applicable two- or three-lane reinforcement in the ultimate limit state

With the vectorial representation of the main stress directions of the internal forces, it is possible to optimally adapt the alignment of the third reinforcement path to the loading

Design variants to avoid bending pressure reinforcement or shear reinforcement

Design of surfaces as wall-like beams (disk theory)

Possibility to define basic reinforcements for the upper and lower reinforcement layers

Definition of the existing reinforcement for the serviceability limit state test

Result output in points of any selectable grid

Optional extension of the module with a nonlinear deformation calculation. This is possible on the one hand by a standard-compliant reduction of the stiffness through the module extension RF-CONCRETE Deflect or through a general nonlinear calculation in which the stiffness reduction is determined by an iterative process with RF-CONCRETE NL.

Design with column cutting moments

Precise breakdown of causes of unmeasurability

Design details for all design points for clear traceability of the reinforcement determination

The isolines for the longitudinal reinforcement can be exported as DXF files and used as the basis for reinforcement plans in CAD applications

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 cross-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, you can define, for example, the curtailment of rebars, the number of layers, the cutting ability of links, and the 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.

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 result 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.
