Analysis for several load and design cases
Design based on the buckling field parameters integrated in the cross-section library for the cross-section parts supported on one and both sides
Optional determination of shear stresses according to comment on El. (745)
Possibility to consider the weld thickness in the design of welded cross-sections, which has the effect of a shortening of the cross-section part width
Cross-section optimization with the option to export modified cross-sections
In RFEM and RSTAB, you can visualize the flow field quantities of pressure, velocity, turbulence kinetic energy, and turbulence dissipation rate for the wind simulation.
The clipping planes are aligned with the respective wind direction.
After the design, the results are displayed in different windows sorted by cross-sections, members, sets of members, or x-locations. The corresponding cross-section graphic is always displayed with the result values in tables. In RFEM/RSTAB, they are highlighted by different colors in the structural model. Critical or oversized components can be identified at a glance. You can modify the colors and values assigned.
Result diagrams of a member or a set of members ensure targeted evaluation. It is also possible to represent all intermediate values.
The masses determined during the design are displayed in parts lists for both members and sets of members.
Furthermore, you can export all result tables to MS Excel or in a CSV file. A special transfer menu defines all specifications required for the export.
Do not lose track of stiffnesses and initial deformations. In the individual load cases or combinations, you have the option to modify the stiffnesses of materials, cross-sections, nodal, line and surface supports, and member and line hinges for all or selected members. You can also consider initial deformations from other load cases or load combinations.

Limit loading of general sections
General sections – these include all cross-sections that cannot be assigned to single or double symmetric I-sections, box sections, or pipe sections – can also be designed according to the equivalent member method against flexural buckling. In this case, however, the plastic cross-section properties are determined without interaction conditions. The allowable application limits for this consideration depend on the ratio of the existing internal force to the fully plastic internal force. Five text boxes provide the option for user-defined control.
Check of limit (c/t)
In this dialog section, you can activate or deactivate the check of c/t ratios.
Treatment of Result Combinations
When designing a result combination, a result set is obtained due to the result superposition on each member location, which makes it impossible to clearly determine the moment factors. In this section, you can thus freely specify a global moment factor for a result combination design. The predefined values are on the safe side, regardless of the design method.
After completing the calculation, you will receive an email with a link to download the calculated file. Large files are compressed into a ZIP archive. Smaller files can be downloaded directly.
As an alternative, there is a link to the calculated file in the Extranet.
The downloaded file is a common RFEM file and can be used for further processing as usual.
