Question 1

Is CalcSteel really free to use?

Accepted Answer

Yes. CalcSteel is genuinely free — the Free plan includes the full 3D editor, FEM solver, 1,140+ steel profiles, and code verification per NBR 8800, AISC 360, Eurocode 3, AS 4100 and IS 800. Paid plans ($12–29/month) add project saving, unlimited sheets and clean PDF export. No credit card required to start.

Question 2

What is the best free alternative to SAP2000 and CYPE 3D?

Accepted Answer

CalcSteel is a browser-based alternative focused on steel structures. For steel frame analysis, portal frames, warehouses and code verification you get a workflow comparable to SAP2000 and CYPE 3D — at zero cost. SAP2000 is still needed for complex dynamics, nonlinear analysis and multi-material projects. CYPE remains stronger in concrete, timber and connection design.

Question 3

Which design standards does CalcSteel support?

Accepted Answer

CalcSteel currently verifies steel members per five major international standards: NBR 8800 (Brazil), AISC 360 (USA), Eurocode 3 / EN 1993 (Europe), AS 4100 (Australia) and IS 800 (India). This covers roughly 120+ countries. NBR 14762 for cold-formed sections is also supported.

Question 4

Do I need to install anything to use CalcSteel?

Accepted Answer

No. CalcSteel runs entirely in the browser — Chrome, Firefox, Safari or Edge — using WebAssembly for the FEM solver. There is nothing to install, no license server, no dongle. It works on Windows, macOS, Linux and Chromebook.

Question 5

Can I export my project as a PDF or IFC/BIM file?

Accepted Answer

Yes. CalcSteel generates professional PDF reports with load combinations, internal forces, utilization ratios and design verification tables. IFC / BIM export is available for interoperability with Revit, Tekla and other BIM tools.
