Structural Design Software
for Modern Engineers
Cross-section analysis, cold-formed steel design, and concrete design — all in your browser. Multi-code support for Eurocodes, Australian Standards, and US codes.
Design Tools
Purpose-built tools for cross-section analysis and member design.
GCS — General Cross Section
AvailableDraw arbitrary cross-sections on a CAD canvas. Calculate area, centroid, moments of inertia, section moduli, principal axes, and more.
- Arbitrary polygon sections
- Principal axis analysis
- Composite sections
- PDF reports
LGS — Light Gauge Steel
AvailableThin-walled section analysis with Vlasov theory, FSM buckling curves, and Direct Strength Method design checks.
- Vlasov section properties
- FSM buckling analysis
- DSM design checks
- Multi-code support
ACS — Advanced Concrete Section
AvailableReinforced, prestressed, and post-tensioned concrete section design with biaxial interaction and fire design.
- M-N interaction diagrams
- Moment-curvature analysis
- Fire design (2D FEM)
- Crack width checks
Concrete Column Designer
PlannedReinforced concrete column design with biaxial bending, slenderness effects, and code-compliant detailing.
- Biaxial bending
- Slenderness effects
- Code-compliant detailing
- Multi-code support
Concrete Beam Designer
PlannedReinforced concrete beam design with shear, torsion, and deflection checks.
- Shear design
- Torsion checks
- Deflection checks
- Crack control
Concrete Wall Designer
PlannedReinforced concrete wall design for in-plane and out-of-plane actions.
- In-plane actions
- Out-of-plane actions
- Boundary elements
- Multi-code support
How It Works
Create a Project
Organise your work into projects. Each project contains the tools and sections for a specific structure.
Add Design Tools
Choose from the available tools — GCS, LGS, ACS — and add them to your project.
Design with Confidence
Draw sections, assign materials, run analyses, and generate professional PDF reports with full code references.
