What is StruCalc?

StruCalc 10.0 is the next generation of structural analysis software. The intuitive interface combined with the power to design multiple span members using steel, wood, flitch beams or manufactured lumber propels StruCalc ahead of the competition.

Feel free to browse any of our detailed information pages by following the below links:


  • Steel Angle design-braced or unbraced with leg up or down.
  • Cantilever column design
  • Fully customizable database-add or remove materials and control what sizes appear in StruCalc
  • Round member design
  • Multi-span I-joist design
  • 2006 building codes
  • 2005 NDS values
  • 2005 AISC Steel values
