Steel Girder Support


The ST4 program is used to calculate different types of girder supports. The force can be applied and transferred with or without stiffeners.

  • Structural steel: S235, S275, S355, S450
  • Annealed steel (S275N – S460N)
  • Thermo-steel (S275M – S460M)
  • Weathering steel (S235W – S355W)
  • High-temperature steel (S460Q – S460QL1)
  • Hollow section, hot-finished (S235H – S355H)
  • Hollow section, hot-finished, fine-grain (S275NH – S460NH)
  • User-defined steel
  • Wall support of concrete or masonry with definable intermediate layers (mortar joint, Neoprene support or steel plate)
Structural system


  • Girder on beam
  • Girder on wall
  • Girder on cleat
  • Load on girder
  • Girder on column



  • Girder sections:
    • I-sections as standard shapes
    • Rolled or welded double T-sections as user-defined shapes
  • Column sections:
    • I-sections, square and rectangular hollow sections as standard shapes
    • Double T-sections and rectangular hollow sections as user-defined shapes
  • Load plate:
    • Flat steel and wide flat steel as standard cross-sections
    • Rectangular solid section as user-defined cross-section


  • Support reaction Fd.
  • Design internal forces N, V and M in the girder to consider the joint effect of external transverse load and internal bending moment, internal axial force and internal shear force.

The load introduction is verified in accordance with EN 1993-1-5. The required cross-section verifications are based on EN 1993-1-1. The load introduction via stiffeners is calculated in accordance with Kindmann/Stracke (Verbindungen im Stahl- und Verbundbau, chap. 3.3.). Stiffeners (as full or partial stiffeners) and weld seams are reasonably dimensioned and verified accordingly. The calculation of the bearing stress in concrete and masonry walls is also based on the regulations of the relevant Eurocodes.
