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 design concept of RFEM 6 has been fundamentally changed, so the design cases are no longer available in the add-ons. When defining members and surfaces, you can specify whether to perform design and assign the design properties to the objects. Therefore, it is not possible to perform alternative analyses in the same model.
If you want to design some members according to different specifications, define a new design configuration for a limit state, and assign this configuration accordingly.
If you design both members and member sets, you can use the object properties to control whether to consider each member individually or to analyze the member set as a superordinate object.
Furthermore, RFEM 6 and RSTAB 9 provide you with the option to design objects with common properties using representatives.
A member representative is used as a template for members and represents identical properties, such as material, length, cross-section, and member type. Members with the same properties are combined into one member representative.
The aim of a member representative is to only represent a member with the governing internal forces of the same member type in order to provide you with a good overview in the program and the documentation.
You can activate the members or member set representatives in the general data of the model; see the image. In the "Member Representatives Wizard" tab, you can activate further properties and criteria for defining the representatives.
If you are interested in a particular add-on, you can always contact one of our sales representatives to allow for an individual adjustment of the trial license(s) of the desired products/add-ons.

RF-/LTB requires explicit internal forces over the member axis for the design. This condition is due to various standard requirements that consider the member element to be designed as a structural component, and use result gradients over the member axis to determine the design parameters (axial force distributions, bending moment distributions, and so on).
In order to meet this requirement, the internal forces to be designed must project explicit design cases for the analysis core. Load cases and load combinations are representatives of such explicit design cases. Since result combinations are usually used for the enveloping results, they are locked in RF‑/LTB.
