STATIX Free calculators
Learn

Worked examples, step by step.

Complete design examples to the South African codes. Each one matches a free STATIX calculator, so you can open it with the same inputs and change them.

Guides: how to use the calculatorsShort guides for new users, one per calculator: what each input means with typical values, how to read the result, the governing check and NOT CHECKED, the calc sheet and schedule, and a 2-minute walk-through. Not a course, open to everyone.
