Customer Projects Designed with Dlubal Products

Fascinating customer projects designed with the Dlubal structural analysis software.

Reinforced concrete is one of the most popular building materials.

Use the Concrete Design add-on to perform reinforced concrete design of surfaces (RFEM only), members, and member sets in the ultimate and serviceability limit states.



  • Automatic import of internal forces from RFEM/RSTAB
  • Ultimate limit state and serviceability limit state design checks
  • User-defined limit values and parameters based on the integrated National Annexes (NA)
  • 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 output of results integrated in RFEM/RSTAB; for example, design check ratios or required reinforcement
  • Numerical results clearly arranged in tables and graphical display of the results in the model
  • Integration of the output into the RFEM/RSTAB printout report

Member Design

  • 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

  • Considering tension stiffening
  • Considering creep and shrinkage
  • Fatigue design according to EN 1992‑1‑1, Section 6.8 (see this Product Feature)
  • Simplified fire resistance design according to EN 1992‑1‑2 for Columns (Section 5.3.2) and Beams (Section 5.6) (see this Product Feature)
  • Seismic design according to EC 8 (see this Product Feature)
  • Precise breakdown of reasons for failed design
  • Design details of all design locations for better traceability of reinforcement determination
  • Optional cross-section optimization
  • Visualization of concrete section with reinforcement in 3D rendering
  • Creation of 2D interaction diagrams; for example, M-N diagram
  • Visualization of section resistance in 3D interaction diagram
  • Output of moment-curvature diagram

Surface Design

  • Free definition of two reinforcement layers
  • 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
  • Free definition of provided surface reinforcement
  • Result output in points of any selected grid
  • Design with design moments at column edges
  • Determination of deformation in state II; for example, according to EN 1992‑1‑1, 7.4.3, and ACI 318‑19 24.2.3, Table
  • Considering tension stiffening
  • Considering creep and shrinkage
  • Fatigue design according to EN 1992‑1‑1, Chapter 6.8 (see this Product Feature)
  • Design of a shear joint between the web and flange of ribs
  • Optional pure slab or wall design of surfaces for a 2D model type
  • Precise breakdown of reasons for failed design
  • Design details of all design locations for better traceability of reinforcement determination


Dlubal Software makes many of your work steps easier to support you. Thus, the surfaces, members, member sets, materials, surface thicknesses, and sections defined in RFEM/RSTAB are preset to facilitate the data input. You can use the [Select] function at many places of the program to select the elements graphically. Furthermore, you have an access to the global material and cross-section libraries.

You can group surfaces or members into "Configurations", each with different design parameters. This way, it is possible for you to efficiently calculate design alternatives with different boundary conditions or modified cross-sections, for example. You will be amazed how much faster everything works with RFEM/RSTAB.



Is the design completed? Then you can lean back. The design ratios of the individual design checks (for example, ultimate limit state, serviceability limit state, or compliance with the construction rules) are displayed for you in a table. You can also find the required reinforcement listed in clearly arranged output tables. The program shows you all intermediate values in a comprehensible manner.

You can display the results of members as result diagrams on the respective member. Furthermore, you have the option to document the inserted reinforcement for longitudinal and stirrup reinforcement, including sketches, in accordance with current practice.

Select whether you want to display the results of surfaces as isolines, isosurfaces, or numerical values. In addition to the design check ratios, you can display the longitudinal reinforcement according to required, provided, and not covered reinforcement.
