Built by engineers, for engineers
StructLib is made by structural engineers and software developers working together.
What we build
StructLib is structural analysis and design software. Structural models and analyses 3D frames and plates and checks members to steel, concrete and timber codes; Connection Design, Quick Design and SeismoLab cover connections, single-element checks and seismic work. It runs in the browser, and Structural can also run in the cloud or as a desktop app — with the same solver everywhere.
Who builds it
The people behind StructLib combine structural engineering practice with software development. Engineers decide what a result has to mean and which published source it must agree with; developers make sure the software keeps agreeing with it after every change. We are a small team, and we would rather say plainly what the software does not do yet than let it give an answer that only looks right.
How it is checked
Against published sources
Steel design replays 28 worked examples from published design guides, and the analysis runs published verification examples and exact closed-form solutions.
On every change
Each check is an automated test through the same code you use. The app is not deployed unless every one of them passes.
Refused by name
When the software cannot handle part of a model, it says which element and why, instead of quietly falling back to a different answer.
Open about the gaps
The Verification page lists what each check compares — and what has not been checked yet.

Questions, feedback or a model that does not behave as you expect: write to [email protected]. You remain responsible for your design — and a well-described problem helps us fix the software for everyone.
