Frequently Asked Questions (FAQ)

AnswerYes, it is possible to exchange data between the LayPLAN software by Layher and RSTAB. The "LayPLAN TO RSTAB" tool allows you this.
You can easily transfer scaffolding structures to RSTAB. The "LayPLAN TO RSTAB" interface transfers geometry data as well as statically relevant information, such as cross-section and material data, member types, eccentricities, and nonlinear joint definitions according to the approval.
To operate this interface, an active license of RS‑COM to RSTAB is required.
A perpetual license or a rental license is available for RS‑COM.
The "Simulate and Generate Wind Loads" interface application allows you to exchange member, surface, and solid elements in RFEM, and member elements in RSTAB.
To avoid too fine mesh and thus too long calculation time, the program simulates all members with a rectangular cross-section by default. In this case, the size of the rectangular cross-section is selected in such a way that it barely includes the real cross-section geometry.
By deactivating the "Export optimized member topology" option, you can avoid this additional optimization of the model and allow consideration of the real cross-section geometry within the existing cross-section settings.
If the exact display of the cross-section geometry requires more than 1,000,000 elements, the interface automatically switches to the simplified rectangular cross-section display.
AnswerRSTAB is a pure framework program and only determines internal forces, deformations, and support reactions.On the other hand, stresses are variable depending of the cross-section and are calculated on the stress points of a cross-section. This stress determination is performed in the RF-/STEEL add-on module by calculating the existing stresses and comparing them with the limit stresses.
The following points should be taken into account so that the calculated internal forces can be used for the design:
The model should reflect the real structure as accurately as possible. For this purpose, materials, surface thicknesses, cross-sectional dimensions, joint definitions, support conditions, etc. must be defined correctly.
The loads must be defined and applied in accordance with standards. The combinatorics can be automatically adopted by RFEM.
For internal forces of result combinations, attention must be paid to the evaluation of the correct max / min values. The maximum compressive force in a column corresponds to the minimum normal force (min N).

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
