CivilAxis is a global structural engineering platform that brings standards reference across Eurocode, American and TCVN, AI-assisted calculation tools, and a community of engineers together in one place - from preliminary sizing to detailed design.
Calculators for wind, sections, beams, welds, anchors, connections and foundations - many working across Eurocode, AISC and TCVN, each showing its assumptions and the clause behind every check.
The Theory Library explains the method behind each tool, alongside searchable Eurocode, AISC and TCVN reference tables and the Design Data lookup for grades, bolts and detailing.
Structural AI answers code questions with clause citations and runs the same verified engines as the tools. Live Connectors link CivilAxis to Revit, Excel and AutoCAD.
Articles written by engineers on real design problems - worked examples, code changes and practice notes, published in English and Vietnamese.
Your private space: save tool projects to reopen later, plus notes, tasks, a calendar, finance tracking and photo milestones.
A feed for engineers - ask questions, share what you are working on, and follow people whose work you want to keep up with.
Every calculation engine is written against the published code text and checked against worked examples, so a result can be traced back to the clause it came from. Each tool states its assumptions and its limits on the page, and names the clause behind each check - the aim is a calculation you can follow and verify, not a bare pass or fail.
Section properties are taken from the published tables of each standard - EN, BS, AISC and TCVN - and every size has its own page with full dimensions and properties, so the values match what you would read from the code.
CivilAxis is a design aid, not a substitute for engineering judgement. Always verify every result independently against the governing code and your own calculations before using it in design.
