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.
It's possible to select an existing cross-section from the program library and edit the parameters with the "convert into parametric section" option.
This will prompt the section dialog box to directly input the modified dimensions.
It's further possible to use this member in the model for the static analysis as well as design acc. to the various standards in the Design Add-ons.
RFEM 5 and RFEM 6 will have separate service contracts with the two levels Basic and Pro available for both generations. You can maintain your RFEM 5 service contract to continue receiving program updates and priority tech support. If you choose to discontinue the RFEM 5 service contract, you can continue using the program but will no longer have access to any program updates.
One significant difference from the RFEM 5 service contract is that when a service contract is purchased for RFEM 6, it will also be required to purchase a service contract for each add-on. The reason for this is you now have access to all national and international standards for a given material (e.g. concrete design acc. to ACI 318, CSA A23.3, EC2, etc. in one add-on). Program updates will include significant updates for the add-ons including the addition of new standards when available.
It’s highly suggested that a service contract is purchased for RFEM 6 as significant development will continue over the next several years for this new generation and will be provided through program updates to those with a valid service contract. Both the Basic and Pro levels will provide access to the latest program updates while the Basic will provide priority email technical support only and the Pro will provide priority email, phone, and screen-sharing technical support.
Yes, you can, because the nonlinear reinforced concrete design is also included in the CONCRETE add-on module for RSTAB 8. Thus, you can activate "Nonlinear calculation" in the "Ultimate Limit State" tab.
In the detail settings for the nonlinear calculation, you can select "General design method for members in axial compression acc. to second order theory".
It is important to define the imperfections in RSTAB and to use load combinations (CO) according to the second-order analysis, not result combinations (RC)!
Note on RFEM 5:
In RFEM 5, the same procedure is possible in RF‑CONCRETE Members. However, RFEM requires the RF‑CONCRETE NL add-on module for the nonlinear reinforced concrete design.
