Add-on Module for RFEM 5
RF-STEEL

• General stress analysis
• Automatic import of internal forces from RFEM/RSTAB
• Complete graphical and numerical results of stresses and stress ratios integrated in RFEM/RSTAB
• Wide range of customization options for graphical output
• Flexible design in multiple design cases
• Clearly arranged result tables for a quick overview after the design
• High productivity due to the minimal amount of input data required
• Flexibility due to detailed setting options for basis and extent of calculations

• Determination of principal and basic stresses, membrane and shear stresses, as well as equivalent stresses and equivalent membrane stresses
• Stress analysis for structural surfaces including simple or complex shapes
• Equivalent stresses calculated according to different approaches:
  • Shape modification hypothesis (von Mises)
  • Shear stress hypothesis (Tresca)
  • Normal stress hypothesis (Rankine)
  • Principal strain hypothesis (Bach)
• Optional optimization of surface thicknesses and data transfer to RFEM
• Serviceability limit state design by checking surface displacements
• Detailed results of individual stress components and ratios in tables and graphics
• Filter function for surfaces, lines, and nodes in tables
• Transversal shear stresses according to Mindlin, Kirchhoff, or user-defined specifications
• Parts list of designed surfaces

After the calculation, the maximum stresses and stress ratios are displayed sorted by sections, members/surfaces, member sets, or x-locations. In addition to the tabular result values, the corresponding cross-section graphic with stress points, stress diagram, and values is displayed as well. The design ratio can be related to any kind of stress type. The current location is highlighted in the RFEM/RSTAB model.

In addition to the result evaluation in the module, it is possible to represent the stresses and stress ratios graphically in the RFEM/RSTAB work window. It is possible to individually adjust the colors and values.

Result diagrams of a member or set of members facilitate targeted evaluation. Furthermore, you can open the respective dialog box of each design location to check the design-relevant section properties and stress components of any stress point. It is possible to print the corresponding graphic, including all design details.
