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.
The difference between the two analysis methods "Finite Element Analysis" and "Thin-Walled Analysis" is the calculation of the cross-section properties and the stresses on the gross cross-section.In the case of the finite element analysis, the calculation is carried out according to the FE method. In the case of the thin-walled analysis, the calculation is essentially carried out analytically according to the method for the calculation of thin-walled cross-sections, whereby it is assumed that the force flow does not occur transversely to the respective element, but along the center line.
If you have a cross-section consisting of any polygonally limited surfaces with or without cutouts, the finite element analysis is suitable as an analysis method (formerly SHAPE‑MASSIVE).On the other hand, if there is an open, closed, or connected cross-section consisting mainly of thin-walled elements, the thin-walled analysis is suitable (formerly SHAPE‑THIN).
No, load generation, such as "Surface Load on Members via Plane", only works for straight or articulated straight members.
If necessary, curved members can be converted into polygonal members as follows:
We recommend creating separate load cases for each span to be loaded. It is then necessary to generate the loads by span in the individual load cases. Free rectangular or polygonal loads allow you to enter surface loads on a freely definable area of the surface. As an alternative, you can divide the surface into partial surfaces and apply the surface load.
Furthermore, it is possible to use the RF‑MOVE Surfaces add-on module to create load cases including loads.
You can then create the checkered arrangement of the loads in the load combinations or result combinations by combining the individual load cases.
The video shows the manual creation and generation of load cases and loads with RF‑MOVE Surfaces.
Basically, there are two options:
