Which programs and modules are suitable for the calculation and design of steel structures?

Answer

Both RFEM and RSTAB present a suitable solution. Numerous European and international standards, as well as various add-on modules, are available for both programs, which will facilitate the daily work in steel structures.

Basic programs RFEM or RSTAB
The basic programs RFEM or RSTAB define structures, materials, and actions. In addition to creating spatial frame structures, for example, halls, RFEM also provides plate, pane, and shell structures, making it a more diverse option. It pays off if it is necessary to carry out design also in other areas, such as solid construction.

Available standards
  • EN 1993-1-1 (Eurocode 3),
  • AISC according to ANSI/AISC 360 (US Standard),
  • SIA according to SIA 263:2013 (Swiss Standard),
  • IS according to IS 800:2007 (Indian Standard),
  • BS according to BS 5950-1:2000 (British Standard) or BS EN 1993-1-1 (British Annex),
  • GB according to GB 50017-2003 (Chinese Standard),
  • CSA according to CSA S16-09 and CSA S16-14 (Canadian Standard),
  • AS according to AS 4100-1998 + Annex 1 - 1999 (Australian Standard),
  • NTC-DF according to NTC-RCDF (2004) (Mexican Standard),
  • SP according to SP 16.13330.2011 (Russian Standard),
  • SANS according to SANS 10162-1:2011 (South African Standard),
  • NBR according to ABNT NBR 8800:2008 (Brazilian Standard),
  • HK according to the standard for steel structures 2011 (Buildings Department - Hong Kong)
  • RF-/STEEL - General Stress Designs
Add-on modules for structural steelwork

The functionality of the basic programs is supplemented by add-on modules. With RF-/STEEL EC3, for example, it is possible to perform the design for the structure according to Eurocode 3. The add-on module RF-STEEL Warping Torsion supplements this design according to Eurocode 3 with torsional buckling analysis having up to 7 degrees of freedom, provided it doesn´t refer to a standard case of EC3.

Other more specialized applications such as the plastic design, the stability analysis according to the eigenvalue method or the generation of geometric equivalent imperfections and pre-deformed equivalent models are available. Single modules such as PLATE-BUCKLING provide you with support when designing rigid or stiffened plates. With the SHAPE-THIN add-on module, it is possible to create any thin-walled cross-sections. The cross-section properties are determined and stress analyses or plastic designs can thereby be performed.

The hinged or rigid connections can be designed by means of the RF-JOINTS add-on modules.

The stand-alone application CRANWAY is available for the design of craneways.


Dynamic analysis

If earthquake calculations or vibration analyses are necessary for the building, the RF-/DYNAM Pro add-on modules provide suitable tools for determining natural frequencies and shapes, analysis of forced vibrations, generation of equivalent loads, or for the nonlinear time history analysis.
