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.
When using RF-STAGES, you should pay attention to the following points:
Entering Model
The structure in RF‑STAGES and RFEM may differ due to the definition in RF‑STAGES. Therefore, the structure in RF‑STAGES may be different than in RFEM. In order to find the instability at a certain construction stage, it is necessary to model the structure in this construction stage in RFEM and take it into account separately. In this context, it should also be noted that the entries are not synchronized between RFEM and RF‑STAGES. For example, a member end hinge removed in RFEM is not automatically removed in the RF‑STAGES model.Furthermore, it is important to ensure that the self-weight acts in the same direction in both RFEM and RF‑STAGES. In RF‑STAGES, you can check and adjust this under "Details" → "Calculations" → "Self-Weight".
Method of Analysis
RF-STAGES calculates permanent load cases according to the large deformation analysis. As a result of this analysis, instabilities may occur that are not present in a load case when calculating according to the linear static analysis (critical load problems), for example.
Special Structural Elements
Some of the structural elements available in RFEM are not supported in RF‑STAGES. These structural elements can also cause instability in certain cases. The following structural elements are not fully supported in RF‑STAGES:
