Enter your building and site. StructCalc produces a clause-cited calculation package your licensed engineer reviews and seals. Every number comes from a pure, versioned function — never from a language model.

60 × 120 ft plan, enclosed, flat terrain. The full package adds every clause-traced step, both wind directions, torsional cases, and the Engineer-of-Record flags.
Three things a spreadsheet and a chatbot can't both give you.
The same inputs always produce the same numbers. Every result is a pure TypeScript function in a versioned engine — the package records which engine version made it, so it is reproducible years later.
Every computed quantity carries its ClauseRef — standard, edition, clause — and the formula with your values substituted in. A reviewer checks the arithmetic by hand, exactly as printed.
Each engine check is anchored to a published hand calculation. Values that can't be verified aren't guessed — the code refuses them and lists them for transcription from the official standard.
Buy credits, spend them on packages. A wind package costs 1 credit. No subscription required to start.
We'll email you when StructCalc opens, and when new codes ship.
