Concrete section design, checked and reported in minutes.
XSECTION is a web-based reinforced concrete section design platform for engineers. Build sections, add reinforcement, run multi-code checks, view interaction diagrams and export calculation reports — all from one fast, intuitive workspace.
Built by engineers for engineers.
No learning curve
A clean visual workflow that feels familiar from the first section.
Faster than traditional tools
Build, check, revise and report without slow desktop software or manual formatting.
Advanced when you need it
Interaction diagrams, biaxial bending, strain profiles and force resultants are available without cluttering the workflow.
Built for real projects
Project folders, revisions, load cases, report exports and team libraries are included from the start.
Built for fast, practical section design.
XSECTION gives engineers a clean workspace for modelling concrete sections, checking capacity, reviewing interaction diagrams and producing calculation reports without jumping between spreadsheets, PDFs and desktop tools.
Fast section setup
Create circular, rectangular, wall, pile, pier and custom sections in seconds.
Live design feedback
See utilisation, capacity and warnings as your design develops.
Cloud autosave
Every section, load case and report is saved automatically to your workspace.
Clear calculation outputs
Review inputs, assumptions, diagrams and governing results in one place.
One-click reports
Export clean calculation reports ready for internal review or client submission.
Reusable libraries
Save materials, bar sizes, covers, templates and common section layouts for future use.
Team design templates
Standardise common checks and defaults across your engineering team.
Multi-code workflow
Design using AS 3600, AS 5100, Eurocode 2 and ACI 318 from the same section.
From section to calculation report in minutes.
Rectangle, circle, wall, T, L, bridge pier, pile or custom polygon.
Place bars, layers, circular arrays and standard bar libraries.
AS 3600, AS 5100, Eurocode 2 or ACI 318.
Axial, uniaxial and biaxial bending with interaction diagrams and utilisation.
Review-ready PDF with inputs, assumptions, diagrams and results.
Everything needed for reinforced concrete section design.
Transparent outputs, clear assumptions, versioned reports and review-ready calculations.
Supported Design Codes
AS 3600, AS 5100, Eurocode 2 and ACI 318 from a single section model with consistent inputs and transparent code-specific assumptions.
Library & Arbitrary Section Geometry
Rectangular, circular, wall, T, L, pier, pile and fully custom polygon sections with live canvas preview and dimension-driven editing.
Analysis Types
ULS section capacity, load case stress-strain analysis, column N-M and M-M interaction curves with demand envelopes and governing load cases.
Reinforcement Modelling
Place individual bars, draw rows, generate face reinforcement, and manage bar groups with diameter, material and spacing controls.
Reports & Results
Export branded PDF calculation reports with geometry diagrams, reinforcement layout, interaction curves, code references and versioned results.
One workflow. Multiple concrete design standards.
Code assumptions, material factors and calculation methods are transparent and shown clearly for review.
Building columns, walls, beams and slabs. Covers strength, ductility and detailing to the Australian Standard for concrete structures.
Bridge piers, abutments, pile caps and columns. Appropriate load factors and capacity reduction factors for infrastructure.
Reinforced concrete sections to EN 1992 with national annex support, partial factors and combination rules.
Structural concrete to the American Concrete Institute building code with strength reduction factors and interaction envelopes.
Built for building and infrastructure consultants
Transparent outputs. Verified results.
XSECTION is built for engineering review. Every result links back to geometry, material properties, reinforcement layout, applied actions and force equilibrium — with clear assumptions shown throughout.
| Example | Code | Hand calc | XSECTION | Δ |
|---|---|---|---|---|
| Rectangular column — pure axial | AS 3600 | φNu = 3,847 kN | φNu = 3,851 kN | 0.10% |
| Circular bridge pier — bending | AS 5100 | φMu = 2,140 kNm | φMu = 2,138 kNm | 0.09% |
| Wall section — in-plane | Eurocode 2 | MRd = 847.1 kNm | MRd = 849.2 kNm | 0.25% |
| Biaxial column — interaction | ACI 318 | DCR = 0.88 | DCR = 0.87 | 1.14% |
Review-ready calculation reports.
Every report includes project metadata, geometry diagrams, reinforcement layout, material properties, applied actions, interaction diagrams and versioned results — formatted for internal review or client submission.
