Structural tools
tenstr builds focused, free tools for practising structural engineers — clear inputs, code-based checks, and calculation reports you can follow line by line.
tenstr is pronounced “ten-ster”.
Each tool does one job well. The first ones are in development now.
Cantilever retaining wall analysis, in your browser.
A 2D structural analysis program.
Only the inputs that matter, laid out the way an engineer thinks about the problem.
Every result comes with the calculation behind it, with code clauses, so it can be checked and filed.
The core tools are free to use. Feedback from engineers decides what gets built next.
Send a note and we’ll write when tenstr retain is released. Suggestions for the next tool are welcome too.
