The structural analysis software RFEM 6 is the basis of a modular software system. The main program RFEM 6 is used to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. The program also allows you to create combined structures as well as to model solid and contact elements.
RSTAB 9 is a powerful analysis and design software for 3D beam, frame, or truss structure calculations, reflecting the current state of the art and helping structural engineers meet requirements in modern civil engineering.
Do you often spend too long calculating cross-sections? Dlubal Software and the RSECTION stand-alone program facilitate your work by determining section properties of various cross-sections and performing a subsequent stress analysis.
Do you always know where the wind is blowing from? From the direction of innovation, of course! With RWIND 2, you have a program at your side that uses a digital wind tunnel for the numerical simulation of wind flows. The program simulates these flows around any building geometry and determines the wind loads on the surfaces.
Are you looking for an overview of snow load zones, wind zones, and seismic zones? Then you are in the right place. Use the Geo-Zone Tool to determine quickly and efficiently snow loads, wind speeds, and seismic data according to ASCE 7‑16 and other international standards.
Would you like to try out the capabilities of the Dlubal Software programs? You have the opportunity to do so! The free 90-day full version allows you to thoroughly test all our programs.
Presumably, the "Stress point design also for rectangular and circular cross-sections" option in Details is activated.
Since the stress point design is not allowed for tapered members, this function must be deactivated; see the image.
If this option is to be considered despite the existing tapered cross-sections, the tapered members have to be designed in a separate design case.
Presumably, model type 2D -XY is activated. The 2D - XY type is used, for example, for planar plate structures such as slabs, that are stressed perpendicularly to the surface plane. The "Cable" member type cannot be selected for this model type, however.
As soon as the model type is changed, this member type can be selected again.
Presumably, a material was defined in RFEM whose standard does not match the design standard (for example, a material according to DIN 1045‑1 was selected, but the design is carried out according to DIN EN 1992‑1‑1). Different material standards often use different parameters.
Therefore, we recommend selecting the material standard in RFEM that also applies to the design standard.
Presumably, the Enable Drag & Drop function in the "View" menu has been deactivated (see the image). This feature can prevent objects from being accidentally changed when moving the model view. Enable this feature again.
