STATIX 3D: structural analysis and design in the browser

How it works

From a few settings to a solved building.

Start from a generator or draw it yourself. STATIX builds the load combinations, solves the model and draws the results on the structure.

BuildPick a generator (portal frame, office block, grandstand, bridge...) and set spans, heights and sections. Or draw nodes, members and slabs.

LoadSelf-weight, finishes and imposed load as load cases. STATIX makes the ULS and SLS combinations.

SolveBeams, columns, braces and shell slabs and walls in one analysis. Concrete beams under slabs act as T- and L-beams.

ReadBending, shear, axial force, deflection and slab contours on the model. Support reactions checked against the applied load.

Watch it work

From the gallery to results in one go.

Real screen recordings of the development build, sped up about two to three times: pick a structure, set it up, solve it, turn it round.

Results

The answer drawn on the structure.

Every picture here is a real screenshot of the development build.

Steel portal frame warehouse with member utilisation colours — **Steel portal frame**Member utilisation colours under the governing combination.

Steel portal frame deflected shape — **Deflected shape**The same frame under load, displacements drawn to scale.

Concrete frame with slab deflection contours — **Concrete frame, slab deflection**Contours across every shell slab.

Concrete frame with monolithic T-beams and slab contours — **Monolithic T-beams**Beams and slabs acting together.

The gallery

7 structures, generated and solved.

Each one is built from a gallery generator with a few settings, loaded and solved. Applied load and support reactions agree on every one.

Sixty metre arched hangar — **Arched hangar**60 m clear span on laced columns.

Stadium grandstand with cantilever roof — **Stadium grandstand**Raked seating and cantilever roof trusses.

Truss footbridge with stair towers — **Truss footbridge**42 m Warren truss.

Elevated water tower — **Water tower**Braced steel tower, concrete tank.

Two-level mall with an atrium vault — **Mall with atrium vault**Concrete floors around an atrium under a steel vault.

In development. The models were built and solved in the current STATIX 3D development build under self-weight, finishes and imposed load. They show the analysis, not a finished design. Wind, crane and seismic cases, and full member and connection design, are still being built: see below.

Being built

Loads and design, in the same model.

Working in the development build and being tested. Not released yet.

Reference building in STATIX 3D: two-storey RC frame with slabs, beams, columns, pad footings, a stair and a column on a four-pile cap — **One model, every element**Frame, slabs, a stair, pad footings and a pile cap, each designed in its own window. STATIX 3D, in development.

One click, whole building: design every member, slab and connection of a concrete or steel building in one go, and get the drawings, the bending schedule and the calc pack with it
Wind to SANS 10160-3: a wind module that loads the model: walls and roofs, canopy roofs, multi-span roofs, friction, parapets, free-standing walls and signboards, and the cladding
Crane actions to SANS 10160-6 for crane sheds
Concrete design: beams (with torsion), columns, pad and combined footings, pile caps, RC shear walls, post-tensioned flat slabs, hollowcore and rib-and-block floors, stairs and corbels
Masonry walls: as a line support or as a shell in the analysis, designed to SANS 10164
Steel: member design, and the connections of the frame in the Connection Hub and Studio
Generators: more starting points, among them a hollowcore building, an RC core, a portal frame on pile caps and a crane shed

STATIX masonry wall design window: an unreinforced wall passes 7 of 7 checks to SANS 10164-1, slenderness governing at 33 percent — **Masonry wall design**A wall carrying the floor: 7 of 7 checks to SANS 10164-1. STATIX 3D, in development.

STATIX pile cap in 3D: a column on a cap over four piles, with the top and bottom mats — **Pile cap in 3D**Four piles, top and bottom mats. STATIX 3D, in development.

In development. These parts run in the development build and are being checked against hand calculations before release.

Revit link

From Revit to analysis and back, without redrawing.

A two-way link with Autodesk Revit. Every picture here is a real screenshot of the development build and Revit 2026.

RC frame from STATIX in Revit: pad footings, columns, beams and slab with all reinforcement as native Revit rebar

One model, two programs

Bring the model in: open your Revit structure in STATIX and analyse it
See what changed: when a member is moved, turned or deleted in Revit, STATIX lists exactly what changed and you choose what to accept
Send it back: your changes go back to Revit, so both models stay the same
Reinforcement in Revit: columns, beams, footings and slabs designed in STATIX arrive as real Revit rebar, ready for drawings and schedules
Your own families: STATIX uses your company's Revit families, or makes its own

STATIX import from Revit: list of what changed with tick boxes — **What changed in Revit**A column turned, a member moved, a member deleted. Tick what to accept.

Column cages and starter bars in the pad footings, in Revit — **Columns and footings in Revit**Column bars, links and footing starters as native Revit rebar.

Revit Update from STATIX tick list — **Update from STATIX**In Revit: tick the changes to apply, as one undo step.

Steel connections, from design to fabrication

Model and check: every connection in STATIX, from base plates and haunches to bracing and cleats, checked for strength
Send to Revit: connections go to Revit with their full geometry: plates, bolts, welds and stiffeners
Back from Revit: connections sent from STATIX and changed in Revit come back to STATIX for a strength check
For the fabricator: export an IFC file with every plate and bolt, for the detailer's fabrication drawings

In development. The Revit link is being built and tested; it is not available to download yet. Connection results already travel to Revit on each joint, and a fabrication export of the connections to Advance Steel is in testing. The IFC export with plates and bolts is what we are working towards.
