Anchorage is where a lot of structural review time goes: breakout cones, edge distances, adhesive bond values buried in an ESR, and three manufacturers who each present the data differently. AnchorClaw is being built to do that arithmetic with the citation attached.
Where it stands today: The anchor checks described below run now inside StructuralClaw — cast-in and post-installed, with ACI 318-19 clauses printed into the calc trace. AnchorClaw packages them as a standalone tool. It is not downloadable yet, and the roadmap items further down are not built.
What the engine computes today
Concrete breakout, tension and shear
Tension and shear breakout per ACI 318-19 §17.6.2 and §17.7.2, with the projected-area geometry, edge-distance and spacing modifiers shown as computed values rather than a single answer.
Steel strength and interaction
Anchor steel in tension and shear, plus the combined tension-shear interaction check — the ratio that usually governs a base-plate anchor group.
Adhesive bond, ESR-backed
Bond strength for post-installed adhesive anchors using published ICC-ES values — Hilti HIT-HY 200, Simpson AT-XP and SET-3G, DeWalt Pure110+ — with pryout checked alongside.
How it's built
Code clause on every valueACI 318-19 section and equation printed inline in the calc trace, not a bare 'per code' footnote.
Base plates to AISC DG1Bearing and plate bending per Design Guide 1, with anchor tension and shear carried through to Chapter 17.
Manufacturer data, not marketingBond values taken from published ESR reports for three vendors, stored as data you can inspect.
Same engine as StructuralClawThe anchor modules run today inside StructuralClaw — this is the same arithmetic, packaged on its own.
Pullout (§17.6.3)Anchor pullout strength is not computed yet. It is the next limit state to land.
Side-face blowout (§17.6.4)Not implemented. Required for deep embedment close to an edge — check it independently until this ships.
Seismic provisions (§17.10)Seismic tension and shear and the ductility requirements are not implemented.
Vendor comparisonPutting Hilti, Simpson and DeWalt values side by side to see the governing capacity. The data exists; the comparison view does not.
Standalone desktop appOffline Windows build with the engine split out of StructuralClaw.
