RKALC Platform Updates & Development History

This page records significant RKALC platform updates in reverse chronological order. Entries reflect functional releases and capability expansions. If you require a specific update or have a feature request, please contact us via the contact page.

RKALC Column Update

22 February 2026

  • Batch Solver and Optimiser added to the column module

TribKALC Update

25 January 2026

  • TribKALC has been updated from pixel-based rendering to filled polygons using a Voronoi diagram, resulting in a major performance improvement.
  • All walls and cores now use additional segments, producing smoother results.
  • Zooming and panning are now enabled while results remain visible (previously, zooming or panning cleared the results).
  • Undo and redo are now enabled, with a maximum history depth of 50 steps.
  • The “Show Loads / Show Areas” button has been removed, as all information is now displayed in a single panel.
  • Column Optimiser added, so users can size up their columns by chosing minimum dimension and program works out other dimension under user based parameters such as effective length, MPa, and target refinrocement percentage
