Dlubal RFEM 5 & RSTAB 8 – Design of Shear Force Between Member Web and Flange in RF-/CONCRETE (Members)

By Moritz Bertram, Dlubal Software

With the latest version of CONCRETE and RF-CONCRETE Members, it is possible to perform shear design for the connection of compression and tension flanges on a T-beam web, for example.

For this, you need to select the “Design of flange connections on segmented cross-sections” check box in the “Details” dialog box. In addition, you can select the method by which the longitudinal force difference is determined. There are two methods available: the simplified method using inner lever arm z = 0.9*d without consideration of Mz, and the general integration of stresses in single cross-section parts with consideration of Mz.

The resulting reinforcement as well as the intermediate results are available under results after the calculation.

By Markus Baumgärtel, Dlubal Software

In RFEM and RSTAB, it is now also possible to create a video file of the results of all load cases, load combinations and result combinations. Thus, you can very easily create a visual presentation of a moving load crossing a bridge, for example. This function is available under “Tools” -> “Create Video File”.

By Sonja von Bloh, Dlubal Software

The new “Generate Nodes on Intersection Point of Lines” creates a node at the intersection point of lines without splitting the lines. The function is available under “Tools” -> “Generate Nodes at Intersection Point of Lines”. In the work window, you can simply draw a window over the intersection point where a node is to be generated.

Dlubal RFEM 5 & RSTAB 8 – Editing Parametrized Cross-Section

By Robert Vogl, Dlubal Software

Geometric parameters of a parameterized cross-section are “encoded” in the cross-section description (for example IS 240/100/6/10/0). When editing the cross-section subsequently, you can display the input parameters again: Click the [Edit] button to open the corresponding dialog box where you can modify the parameters.

This function is also useful for editing combined or hybrid cross-sections.

Dlubal RSTAB 8 – Loads Due to Rotary Motion

By Lukas Sühnel, Dlubal Software

As of RSTAB version 8.04.0058, it is possible to consider loads due to rotary motion. This load type is especially useful for crane designs (see a simplified crane in the figure).

For this purpose, you can consider radial and tangential forces resulting from rotary motion. In addition, you can also use this feature for the design of fairground rides such as Ferris wheels or carousels.

By Frank Sonntag, Dlubal Software

In RFEM and RSTAB, there is a new useful option which allows you to check member and line loads entries in the same dialog box. Important settings such as the load direction (local or global), chosen according to the load as well as the reference length, can be easily checked when entering the input data.

This feature provides better efficiency for entering complex loads, since it prevents subsequent editing of member or line load in the case of an incorrect definition.

Dlubal RFEM 5 & RSTAB 8 – Import of Masses with RF-/DYNAM Pro – Natural Vibrations

By Gerlind Schubert, Dlubal Software

Since RFEM version 5.04.xx and RSTAB version 8.04.xx the new module RF-/DYNAM Pro – Natural Vibrations is available. Masses can now be imported directly from load cases and load combinations.

Still, you can define additional nodal, line, member and surface masses, but this is now optional. The masses can be combined in so-called mass combinations where the combination factors are pre-set automatically by RF-/DYNAM Pro – Natural Vibrations in accordance to EN 1990 and EN 1998-1, but can be adjusted depending on your needs.

Dlubal RFEM 5 & RSTAB 8 – Member Rotation About Plane

Dlubal RFEM 5 & RSTAB 8 - Member Rotation About Plane

Dlubal RFEM 5 & RSTAB 8 – Member Rotation About Plane

By Gerhard Rehm, Dlubal Software

If spatially oriented members converge in one node, the local x- or y-axes of the members do not lie in one plane, since the local z-axes are oriented in the direction of gravity. In cases other than what is represented in the figure, this can be easily overlooked in rendering in the case of a small inclination. However, this can be a problem in an RF-/JOINTS design, for example, as the members do not lie in one connection plane. Therefore, the design is not possible.

So it is necessary to rotate the member about the connection plane. Since the manual calculation of the member rotation would be time-consuming, there is an option to rotate a member about any plane. For this, select the “Member Rotation via Help node” check box and define a node located in the desired plane and out of the rotating member at the same time.
