Features
Struxt3D is a complete first-pass analysis and design tool that runs in the browser. Here is what it does, and where to learn each part.
Modelling
Guided setup for speed, a full interface for control.
21 parametric templates
Buildings, industrial sheds, bridges, towers, foundations, single elements and an offshore jacket. See the templates.
Four setup steps
Template, size, materials and supports & loads — each a short panel beside the live 3D model. How it works.
Simple and Full interfaces
A guided workspace, or menus, toolbar, model explorer, properties and tables. Switch any time. The interface.
Draw and edit
Add members, nodes, supports and point or line loads; set end releases and sections per member or group. Editing the model.
Beams, cables and plates
Frames, trusses and cables with 4-node shells for slabs, walls, decks and rafts on soil springs. Plates and meshing.
Undo, save, open
Every change can be undone; work is kept in the browser and can be saved to a file. Saving and exporting.
Loads and analysis
Loads from the code's own rules, solved on your computer.
Load cases and combinations
Self-weight, finishes, live load by floor use, wind in ±X and ±Y, and the code's strength and service combinations. Loads tutorial.
Wind
Basic or gust wind speed per code, applied to the cladding and members. Wind tutorial.
Response-spectrum seismic
Vibration modes, the code's design spectrum and behaviour factor, modes combined by CQC. Seismic tutorial.
Fast 3D solver
A WebAssembly finite element solver running in a background worker, so the page stays responsive. How analysis works.
Results on the model
Deflected shape, axial, shear and moment diagrams, slab moments, reactions and modes, with animation. Reading results.
Tables
Member forces, reactions, displacements, modes and design tables, exportable as CSV. Viewing results.
Design
Checks taken from the codes, with the working shown.
Steel members
Bending, shear, axial, buckling, lateral-torsional buckling and deflection. Steel beams · columns.
Reinforced concrete
Beams, columns, slabs, flat slabs with punching, shear walls and pad footings. RC beams · columns.
Timber and composite
Glulam members, and steel beams acting with the slab, including floor vibration. Composite beams.
Steel connections
Fin plates, end plates, base plates, gussets and splices with bolts, welds and anchors. Connections.
Automatic sizing
The lightest section that passes, and thicker slabs where they fail. Design and auto-sizing.
Six design code families
Eurocode, AISC/ACI with ASCE 7, KDS, CSA with NBCC, AS/NZS and NSCP 2015. Compare the codes.
