Use Cases
Built for real engineering scenarios
From concept design to final deliverables
High-Rise Core Walls
Design shear wall cores for tall buildings. Check capacity under combined axial, shear, and moment demands.
PT Slab Design
Post-tensioned slab analysis with tendon profiles, loss calculations, and serviceability checks.
Concept Comparison
Quickly compare structural options—steel vs concrete, different framing schemes—with consistent metrics.
Review Packages
Generate calculation packages with consistent formatting, ready for QA review and client submission.
How It Works
From input to output in three steps
01
Define Your Inputs
Enter geometry, materials, and loading. Sensible defaults and code-aware suggestions help you move fast.
02
Run Analysis
Calculations execute instantly in your browser. Every step is traceable back to code provisions and first principles.
03
Export & Share
Generate PDF reports, export data to CSV, or save to your project. Results ready for review and submission.
Built by Engineers
Created by practicing structural engineers who understand your daily challenges
We've spent years in consulting firms, wrestling with the same tedious calculations and manual processes you face. Konstrax exists because we built what we wished we had—tools that are genuinely useful, not just impressive demos.

"Finally, engineering software that doesn't feel like it was designed by people who've never sat through a design review. The calculation sheets export exactly how I'd format them manually—saves me hours every week."
FAQ
Common questions
We currently support AS 3600-2018 for concrete design and AS/NZS 1170 for structural loading and load combinations. NZS 3101 support is in progress. We're actively adding support for AS 4100 steel design and additional codes—including Eurocode and SNI (Indonesian standard)—based on user demand.
