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.
Since the method according to 6.3.3 of EN 1993‑1‑1 is only applicable for double-symmetric cross-sections in the case of structural components subjected to bending and compression, the add‑on module designs these components using the General Method according to 6.3.4 of EN 1993‑1‑1. This method is applicable to any single-symmetric cross-sections. In Germany, however, only I‑sections are permitted, which is why the warning appears.
You can perform the stability analysis as cross-section design according to the second-order theory, which is possible using the add‑on modules RF‑/FE‑LTB or RF‑/STEEL Warping Torsion.
As an alternative, you can also allow the General Method for non-I‑sections in the "National Annex" dialog box, but this deviates from the National Annex.
