Recently Released Programs / Add-on Modules

New Add-on Modules

  1. Window 1.6 Reinforcement - tab CSA A23.3-14

    CSA A23.3 for RFEM/RSTAB

    CSA A23.3 for RFEM/RSTAB extends the range of standards for reinforced concrete design with the Canadian standard CSA A23.3 for various add‑on modules.

  2. Representation of cutting pattern on RFEM model


    RF-CUTTING-PATTERN calculates and organizes the cutting patterns for membrane structures.

  3. Cross-Section Properties Software SHAPE-THIN | Result distribution of plastic normal stresses


    The cross‑section properties software SHAPE‑THIN 8 includes many new features as well as the graphical user interface adjusted to RFEM/RSTAB.

  4. Graphical result of required punching shear reinforcement

    RF-PUNCH Pro

    RF-PUNCH Pro performs the design of punching shear resistance for singularly or linearly supported surfaces.

  5. Steel design in RFEM without (left) and with (right) RF-STEEL Plasticity

    RF-/STEEL Plasticity

    RF-/STEEL Plasticity is an extension of the RF‑/STEEL EC3 add‑on module.

    The module extension allows for plastic design of cross‑sections according to the Partial Internal Forces Method (PIFM) and Simplex Method in compliance with the second‑order analysis with 7 degrees of freedom including warping torsion (module extension RF‑/STEEL Warping Torsion required).

  6. Visualization of design results in RFEM


    RF-/ALUMINUM ADM is applicable for the ultimate and the serviceability limit state designs of members according to the American standard ADM 2010 and ADM 2015.

  7. Representation of cross-section warping

    RF-/STEEL Warping Torsion

    RF-/STEEL Warping Torsion is an extension of the RF‑/STEEL EC3 add‑on module.

    The program performs warping torsion analysis of members according to the second-order theory with 7 degrees of freedom and application of imperfections with regard to mode shapes.

  8. Visualization of Sikla connections in RSTAB

    RF-/JOINTS Steel - SIKLA

    RF-/JOINTS Steel - SIKLA performs joint design for fastening connections produced by the Sikla manufacturer (Brackets of type AK and TKO as well as end plates of type STA, WBD, and WD).

  9. Graphical representation of pipelines with loads in RFEM


    The RF‑PIPING module is an extension of RFEM user interface that allows modeling and loading pipelines conforming to standards.

  10. Graphical representation of pipeline analysis results in RFEM

    RF-PIPING Design

    RF‑PIPING Design performs piping design based on modeling in RF‑PIPING. The module compares the existing pipe stresses with the allowable stresses according to ASME B31.1 and ASME B31.3.

  11. Results graphics with design ratio


    RF‑/STEEL HK designs steel members and sets of members for the ultimate and the serviceability limit state according to the Code of Practice for the Structural Use of Steel 2011 (Buildings Department - Hong Kong).

  12. Graphical representation of RF-/TIMBER SANS design results in RFEM


    RF-/TIMBER SANS performs the ultimate and serviceability limit state designs and fire resistance designs according to the South African timber construction standards SANS 10163‑1:2003 and SANS 10163‑2:2001.

  13. 1.2 Geometry

    RX-TIMBER Roof

    RX-TIMBER Roof performs the ultimate and serviceability limit state design as well as fire resistance design of monopitch and duopitch roofs according to EN 1995‑1‑1.



    RF-/TIMBER NBR performs the ultimate and serviceability limit state design for members according to the Brazilian timber construction standard NBR 7190‑1997.



    RF-FORM-FINDING finds the shapes of membrane and cable constructions. The shape is found by using the equilibrium between the surface stress (loading prestress) and the natural and geometrical boundary reactions.

  16. RF-/JOINTS Steel - Pinned

    RF-/JOINTS Steel - Pinned

    With RF-/JOINTS Steel - Pinned, you can configure and design shear connections of I‑beams according to EC 3.

    Four different types are available: Web cleat connection, fin plate connection, short end plate connection, and end plate connection with cleat.
