Defining Nonlinearity of Support Conditions at Nodal Supports
Friction plays an important role in practice. Without friction, the brakes of cars would be useless, objects on inclined planes would just slide away, and prestressed bolt connections would be impossible.
Generate Catenary
RFEM and RSTAB are able to cover a large number of branches in the building and construction industry with their generally usable structural frame analysis and FEM programs. Designing cable structures is thus also possible in both software solutions. Some assistance tools for modeling and design will be presented in the following text.
Snow Load Zones of Germany
In Germany, DIN EN 1991-1-3 with National Annex DIN EN 1991-1-3/NA regulates snow loads. The standard applies to civil engineering works at altitudes of up to 1,500 m above sea level.
KB 001880 | Design of Cable Structures in RFEM 6 and RSTAB 9
In this article, you will learn how to model and design cable structures in RFEM 6 or RSTAB 9.

Product Features
Aluminum Design in RFEM 6
  • Calculation of deflections and comparison with the normative or manually adjusted limit values
  • Consideration of a precamber for the deflection analysis
  • Different limit values are possible, depending on the design situation type
  • Manual Adjustment of Reference Lengths and Segmentation by Direction
  • Calculation of deflections related to the initial structure or to the deformed structure
  • Further detailed design checks depending on the selected design standard (for example, vibration design according to EN 1999‑1‑1, 7.2.3)
  • Graphical result display integrated in RFEM/RSTAB; for example, the design ratio of a limit value, or the deformation or the sag
  • Complete integration of the results into the RFEM/RSTAB printout report
Aluminum Structure, Deformation
  • A wide range of available sections, such as rolled I-sections; channel sections; T-sections; angles; rectangular and circular hollow sections; round bars; symmetrical and asymmetrical, parametric I-, T-, and angle sections; built-up cross-sections (suitability for design depends on the selected standard)
  • Design of general RSECTION cross-sections (depending on the design formats available in the respective standard); for example, equivalent stress design
  • Design of tapered members (design method depending on the standard)
  • Adjustment of the essential design factors and standard parameters is possible
  • Flexibility due to detailed setting options for basis and extent of calculations
  • Fast and clear results output for an immediate overview of the result distribution after the design
  • Detailed output of the design results and essential formulas (comprehensible and verifiable result path)
  • Numerical results clearly arranged in tables and graphical display of the results in the model
  • Integration of the output into the RFEM/RSTAB printout report
Feature 002808 | Independent FE Mesh

Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.

Feature 002807 | 3D Display of FSM Results

In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
