Structural Engineering · Coming Soon

Structural calculations with the code section attached.

Every value carries the governing code section and equation — concrete, steel, wood, masonry, seismic and loads — with an audit trail you can hand straight to a reviewer.

StructuralClaw isn't a black box. Ask it for a beam and you get the demand, the capacity, the ratio — and the ACI / AISC / NDS / ASCE 7 clause behind each number. A licensed engineer of record stays responsible for the design; StructuralClaw shows its work so the review is fast.

Why engineers will reach for it

Code-cited every value

ACI 318-19, AISC 360-22, NDS 2018, ASCE 7-22, IBC 2021 — section + equation on every value in the calc trace.

LRFD & ASD

Both design methods, side by side, with the governing load combination shown.

Reviewer-ready audit trail

Every input, factor and step recorded — hand the package to a checker without re-deriving.

One workflow, every material

Concrete, steel, wood, masonry, seismic and loads — the same consistent flow across the board.

A look inside

Screenshots from the actual app — the project workspace and a few representative modules.

StructuralClaw project workspace with the module catalog and project tree

Project workspace

One project file, many module instances — beams, columns, footings, walls and loads live side by side with a shared load-combination set.

StructuralClaw beam analysis workspace with a steel W-shape over a span

Beam analysis

Lay out spans and supports, pick the material, and design to the governing combo — steel, wood, glulam or concrete in one place.

StructuralClaw code reference lookup panel

Code reference

Which IBC edition adopts which ASCE 7, NDS, AISC, ACI, TMS and SDPWS editions — and what changed in each cycle — without leaving the app.

Steel base plate with anchor rods — anchorage design lives in AnchorClaw

Sister product — AnchorClaw

Anchorage to concrete and masonry — cast-in and post-installed anchor design per ACI 318-19 Ch 17 with manufacturer ESR data — is its own product: anchor-claw.com. StructuralClaw covers the members and connections; AnchorClaw covers the anchors.

The same output, code citation and all

Two worked examples — exactly what the app produces.

① Steel beam — lateral-torsional buckling (AISC 360-22 §F2)

W18×50Lb = 12 ftCb = 1.14Fy = 50 ksi
Lp = 5.83 ft · Lr = 16.9 ft → inelastic LTB region (§F2.2)
Mn = 377 kip·ft → φMn = 0.90 × 377 = 339 kip·ft   vs Mu = 268 kip·ft → ratio 0.79 ✓

② Wood shear wall — unit shear capacity (SDPWS 2021 §4.3)

15/32" plywood8d @ 4" edgeblockedL = 8 ftASD · CD = 1.0
vn = 870 plf → Table 4.3A · aspect ratio 1.0 ✓ (§4.3.4)
v'allow = 870 / 2.0 = 435 plf   vs demand 380 plf → ratio 0.87 ✓
