About AStrutTie
The strut-and-tie design tool built by structural software engineers — and verified against the codes.
Built by HanGil IT
AStrutTie is developed by HanGil IT, a software company building structural and infrastructure design tools for public-sector engineering since 1997.
- Software trusted in public infrastructure engineering, where a wrong number is not an option.
- We automate structural calculation and drawing so engineers spend their time on judgment, not busywork.
Why we built it
Strut-and-tie modeling is the rigorous way to design D-regions — deep beams, corbels, pile caps, anchorage zones — but doing it by hand is slow and easy to get wrong.
AStrutTie makes the full workflow fast: geometry → model → code checks → a submittable report, with every number traceable to a design code.
Verified, not asserted
Every release is checked against independent oracles and a public ledger — the checks a competitor hides, we publish. See the verification ledger · Your data & AI policy
A discipline, rebuilt
AStrutTie was first released in Korea in 2014, and went international in 2016 with an English edition and major design codes — ACI, AASHTO, Eurocode 2. That is the product today's version builds on, resting on HanGil's structural-software lineage since 1997. The current generation is a ground-up rebuild: a new engine and interface, the same verification-first discipline.
