AnchorClaw

Beta coming soon

Anchor design with the code clause on every value.

Cast-in and post-installed anchors to ACI 318-19 Chapter 17, base plates to AISC Design Guide 1, and ESR-backed manufacturer data, with the section and equation printed next to every number. A Windows desktop app.

We will only email you about AnchorClaw. We do not sell lists. Unsubscribe in any email.

Anchorage, with the citation attached

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 does that arithmetic and shows its working.

Where it stands today: the anchor checks below run now inside StructuralClaw, with ACI 318-19 clauses printed into the calc trace. AnchorClaw packages them as a standalone desktop tool. The beta has not opened yet, and items marked Coming are not built.

What it computes today

  • Anchor bolt design form showing ACI 318-19 Chapter 17 inputs

    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 is built

  • Code clause on every value

    ACI 318-19 section and equation printed inline in the calc trace, not a bare "per code" footnote.

  • Base plates to AISC DG1

    Bearing and plate bending per Design Guide 1, with anchor tension and shear carried through to Chapter 17.

  • Manufacturer data, not marketing

    Bond values taken from published ESR reports for three vendors, stored as data you can inspect.

  • Same engine as StructuralClaw

    The anchor modules run today inside StructuralClaw. This is the same arithmetic, packaged on its own.

Coming

  • Pullout (§17.6.3)Coming

    Anchor pullout strength is not computed yet. It is the next limit state to land.

  • Side-face blowout (§17.6.4)Coming

    Not implemented. Required for deep embedment close to an edge: check it independently until this ships.

  • Seismic provisions (§17.10)Coming

    Seismic tension and shear and the ductility requirements are not implemented.

  • Vendor comparisonComing

    Hilti, Simpson and DeWalt values side by side to see the governing capacity. The data exists; the comparison view does not.

How it works

  1. Enter the anchor group

    Anchor type, geometry, edge distances, concrete and loads.

  2. Read the checks

    Every limit state is computed with its working shown and the code clause beside it.

  3. Follow the governing one

    Utilisation ratios show which check governs, so the review goes to the right place.

How licensing works

  • Free account: sign in and use a limited online version of AnchorClaw, 20 minutes per session. Coming
  • Tier 1: the AnchorClaw desktop program, downloaded after you sign in and licensed for your computers while you are signed in, one running copy per computer.
  • The licence is for AnchorClaw only; each program is licensed on its own.
  • During the beta, invited members download the installer after signing in. Pricing has not been announced.

Questions

When does the beta open?

Soon. Join the beta with your email and you will hear the day it opens. That is the only announcement channel.

What does it run on?

A Windows desktop app. The anchor engine already runs inside StructuralClaw today.

Which codes and data does it use?

ACI 318-19 Chapter 17 for anchors, AISC Design Guide 1 for base plates, and published ICC-ES evaluation reports for Hilti, Simpson and DeWalt adhesive anchors.

Does it replace the engineer of record?

No. AnchorClaw is informational and not a substitute for a licensed engineer's judgement. The engineer of record remains responsible for the design.

What is not built yet?

Pullout, side-face blowout, the seismic provisions and the vendor comparison view are marked Coming above. Check those limit states independently until they ship.

The beta opens soon
