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
ACI 318-19, AISC 360-22, NDS 2018, ASCE 7-22, IBC 2021 — section + equation on every value in the calc trace.
Both design methods, side by side, with the governing load combination shown.
Every input, factor and step recorded — hand the package to a checker without re-deriving.
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.
Project workspace
One project file, many module instances — beams, columns, footings, walls and loads live side by side with a shared load-combination set.
Beam analysis
Lay out spans and supports, pick the material, and design to the governing combo — steel, wood, glulam or concrete in one place.
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.
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)
② Wood shear wall — unit shear capacity (SDPWS 2021 §4.3)
What it covers
Design modules, by category
The catalog spans the members a building practice actually designs — grouped the way the app groups them.
Continuous, cantilever, flitch, composite, crane, aluminum, cold-formed — wood, steel and concrete flexure in one flow.
Wood, steel, concrete and generic sections — stability, slenderness, and combined axial + bending.
Spread, combined, strip and mat foundations, pile caps, piers, helical piles and soil bearing.
Cantilever retaining wall stability and strength, plus grade beams on soil.
Wood stud and shear walls, diaphragms, slender concrete panels, masonry and ICF walls.
Welds, bolts, holdowns, ledgers, wood dowels and prequalified moment connections.
Concrete slab on composite metal deck — construction and composite stages.
Pipe and HSS members, trusses, one- and two-way slabs, punching shear, stair stringers.
ASCE 7-22 Ch 7 snow — balanced, unbalanced, drift, sliding — and Ch 10 atmospheric ice.
MWFRS directional (Ch 27), envelope (Ch 28), components & cladding (Ch 30), signs and other structures (Ch 29).
ELF base shear (§12.8), diaphragm forces, component Fp (Ch 13), nonbuilding structures (Ch 15), SMF and braced frames per AISC 341.
