Free online truss calculator. Fun intended.
More serious than a bridge builder game, less scary than a CAD app.
From the classroom to the engineering office. No account, no install.
Features
Build by drawing
Draw, drag, clone and mirror — sketch a truss as fast as you'd doodle one.
Instant results
Move a node or change a load and the forces, reactions and displacements update live.
Deformed shape
Watch the structure bend under load — animated, not just a table of numbers.
Works everywhere
Runs in the browser on a phone, tablet or laptop. Nothing to install.
2D truss analysis
Real linear static analysis under the hood — the same direct stiffness method the textbooks teach.
Indeterminate structures
Add as many pinned or roller supports as you like; statically indeterminate cases are handled too.
Stability check
Get a heads-up when a structure is unstable or under/over-determined, before you trust the numbers.
Material & section input
Plug in real materials and cross-sections for actual deflections, not just force diagrams.
DXF import/export
Move designs between Truzme and your CAD tools via DXF.
What people are saying
A few of the kind words I've received — and there's always room for more.
“Truzme allows students to check their work and get instant feedback. [...] As a teacher this is the Holy Grail scenario for apps. Thank you so much for your contribution to the engineering world!”
“Finding a fully-featured, easy to use, interactive truss solver has been a challenge for many years. [...] Thank you Norbert, you have really cool software, and you share it with the world it is very kind!”
“A remarkable tool! I'm getting addicted to it! Congrats!”
“I just learned about it today thanks to a student who shared it with me. Pretty cool tool to explore structural engineering and truss designs.”
“Interesting, easy-to-use tool for simplified analysis / estimates. Congrats for your work!”
Used Truzme? I'd love to hear about it. Send me a message or reach out on LinkedIn — or leave a review on Buy Me a Coffee.
Master structural engineering
and have some fun
Built by one person, for everyone
Truzme is a solo project - no team, no investors, no ads. I'm a father, building and maintaining this in the early mornings so it stays free for students and engineers worldwide.
