GSA-Compos integration​

Limitations​

Specification​

  • Only EN 1994‑1‑1:2004 and AS/NZS 2327:2017 are supported as composite design codes.
  • Steel grades must be selected only from the chosen composite design code.

Materials​

  • Composite beams can only be specified as made of steel.

Properties​

  • Only STD I, STD GI, and catalogue I sections are supported for composite members.
  • Tapered sections are not supported.
  • Shear studs must be present.
  • Stud free zones (left or right) cannot be defined.
  • Automatic shear‑stud spacing is not available.
  • Reinforcement position cannot be defined for shear stud positioning.
  • Only solid and decking slab types are supported.
  • The slab is required to be of uniform thickness over its entire surface.
  • The slab associated with a composite beam must use a single slab property throughout the available width region.
  • The slab associated with a composite beam must have a constant decking orientation throughout the available width region.
  • User-defined decking angles on the 2D slab property (Composite Decking Details) are not supported. The decking angle used for the Compos export is calculated from the relative orientation of the composite beam and slab direction

Design​

  • Only Mesh Type A is permitted for 2D‑member mesh reinforcement.
  • Transverse reinforcement is not supported.

Members​

  • Composite members must be formed using exactly two nodes.
  • Only rectangular and circular web openings are supported.
  • Member axes and slab edges must align.

Loading​

  • Loads causing minor‑axis effects are not supported.
  • User‑defined safety factors for loading in the design task are not allowed.
  • Point restraints at construction or final stage cannot be set in GSA.
  • Self-weight and potential load distribution variation due to web openings are not considered.
