For structural & civil engineers
Engineering Calculations, Detailed and Verifiable
Run production-grade calculations in your browser. Every formula and step prints into a PDF report with code references; production-ready DXF drawings come with it. Take control with calculations you can audit, defend and publish.
Nothing to install, always up to date — on any computer, anywhere.

The platform
Four pillars, one platform.
StructuralMind rests on four core pillars.
Detailed engineering calculations
02Publishing & verification
03API integration into your workflow
04Team collaboration & project review
Production-grade, detailed calculations
A deterministic engine puts every formula, calculation step and code reference in the report and generates production-ready detail drawings. The library grows with new calculations every month.
EngineerFiber Section Analysis
Moment-curvature, PMM interaction surfaces and prestressing tendon support.
EngineerRC Column Design
Biaxial interaction, auto rebar and confinement checks — TS500 & TBDY 2018.
EngineerSpun Concrete Pole Design
Reinforcement zone optimization, capacity envelope, design report and shop drawings.
Not a black box — an auditable, defensible, publishable Glass Box
The Glass Box shows every formula, intermediate step and code reference. Finish your calculation and publish the read-only snapshot you approved; the PDF report links to that digital publication. So anyone you share the PDF with can confirm — in the office or in the field — that the report is genuinely yours and unchanged.

Bring it into your own workflow
StructuralMind is API-first. Every calculation is a REST endpoint. Call the same deterministic engine you use in the web app from the tools you already work in — your structural software, your own automation scripts, BIM models, and even inside Excel. You can call the same REST API from your AI agents or your own MCP server.

StructuralMind is organization-based. Your whole team works to the same company standard, together on projects. Share a project — exactly as you approved it — for external review with municipalities, chambers and independent reviewers, read-only and fully digital; their comments are tracked and resolved on the platform. When a team member leaves, all of their calculations stay with the firm.
