  1. Stress Analysis of the End Plate According to the Hypothesis of von Mises with RF-STEEL Surfaces

    Designing End Plate Connection of Hollow Sections Under Tension According to the CIDECT Method and by Means of the FEM Model

    A site joint consisting of hollow sections with end plates will be designed. It is the bottom chord of a truss which has to be divided for transport reasons.

  2. Figure 01 - Frame Joint in RF-/FRAME-JOINT Pro

    Analysis of Load-Bearing Capacity of Bolted Frame Joints According to EC 3-1-8

    When designing bending-resistant connections from I‑beams, the connection is dissolved into the individual parts. For these basic components of a joint, there are separate formula calculators for load‑bearing capacity and stiffness. In RFEM and RSTAB, it is possible to design frame joints using the RF‑/FRAME‑JOINT Pro add‑on module.

  3. Identification of Licensed Joint Groups in RF-/JOINTS

    Identification of Licensed Joint Groups

    As of the program version X.06, joint groups are clearly identified in RF‑/JOINTS.

  4. New Results Navigator in RF-JOINTS

    New Results Navigator

    The updated Results Navigator of RF‑JOINTS allows you to simultaneously display results of different module cases. Thus, you can display all column base designs at the same time in order to perform collision checks of the foundations, for example.

  5. Consideration of Eccentricities in RF-/JOINTS Timber - Steel to Timber

    Consideration of Eccentricities

    In RF-/JOINTS Timber - Steel to Timber, it is possible to consider the eccentricities of a connection during the calculation. The figure shows different internal forces without consideration of the eccentricity (above) and with consideration of the eccentricity (below).

  6. Deactivation of Individual Dowels in RF-/JOINTS Timber - Steel to Timber

    Deactivation of Individual Dowels in RF-/JOINTS Timber - Steel to Timber

    In RF‑/JOINTS Timber, it is possible to remove an individual dowel from the calculation, and thus create any dowel layout. The calculation disregards these removed dowels for the ultimate limit state design as well as for the net timber cross‑sections analysis and the rotational spring stiffness determination.

  7. Display Options for 3D Graphics in RF-/FRAME-JOINT Pro and RF-/JOINTS

    Display Options for 3D Graphics

    In addition to the result tables, it is possible to create a three-dimensional graphics in RF‑/FRAME‑JOINT Pro and RF‑/JOINTS. This is a realistic representation of the connection to scale.

  8. DSTV Library for Connections in RF-/LIMITS

    DSTV Library for Connections

    RF‑/LIMITS analyses the ultimate load capacity of timber and steel connections. The ultimate elastic capacity of joints according to DSTV has now been implemented in the add‑on module. The library has been extended to include the connection types IH, IS, IW, IG, IK and PM. The filter functions ensure a comfortable selection of the connections. If the designs are not fulfilled, you can determine an optimization function for the connection from the DSTV Library.

  9. Figure 01 - Dlubal RFEM 5 & RSTAB 8 - Automatic Data Import or Manual Data Input for Analysis of a Hollow Section Node in RF-/HSS

    Automatic Data Import or Manual Data Input for Analysis of a Hollow Section Node in RF-/HSS

    In the RF‑/HSS add‑on module, you can analyze the connections for nodes at which hollow sections join. In addition to importing the geometry and loads from RFEM or RSTAB, you can also define the nodal parameters manually. Thus, you can also check existing connections without creating the truss model in RFEM or RSTAB.
