v2.0.0
stableAStrutTie 2.0 — a ground-up rebuild. Strut-and-tie model (STM) design for D-regions, running in your browser and verified against published hand calculations.
Design codes Added: KDS · ACI 318 · AASHTO LRFD · Eurocode 2
New
- A library of STM templates across common D-regions — deep beams (simple & continuous), corbels, girders, bridge pier caps (single & multi-column), spread / pile / abutment foundations, 3D pile caps and pile-grid foundations, post-tension anchorage zones, PSC box cross-sections, anchor plates, and frame corners.
- Multi-code strut / tie / nodal-zone checks — KDS, ACI 318, AASHTO LRFD, and Eurocode 2.
- 2D and 3D models, with ESO topology assistance for laying out struts and ties.
- Submittable HTML reports (open in Word · print to PDF) and DXF import / export for round-tripping with CAD.
- Runs in the browser with no install; a Windows desktop build is also available.
- Every result is checked by an automated gate suite against published hand calculations, SAP2000, and an independent oracle — with the remaining gaps published openly.
Known limitations
- At this release, Windows desktop installers were still being finalized through code signing.
