Frequently Asked Questions

What is Autodesk Robot Structural Analysis used for?

Robot Structural Analysis Professional is used for finite element analysis and code-based design verification of buildings, bridges, and industrial structures. Structural engineers use it to model loads, run linear and nonlinear analysis, verify steel and concrete members against international codes, and prepare design documentation.

Does it work without internet or an Autodesk account?

Yes. The version available in this store runs fully offline after installation. No internet connection is required during use, and no Autodesk account is needed to open or run the software.

What file formats does Robot Structural Analysis support?

Robot Structural Analysis uses .rtd as its native project format. It supports IFC for BIM exchange, DXF and DWG for drawing export, CIS/2 for steel fabrication interoperability, and Excel (.xlsx) and PDF for results and reports.

What design codes does it include?

The software includes 70+ international design code libraries: US AISC and ACI standards, European Eurocodes with national annexes, Canadian CSA, Australian AS standards, and country-specific codes. All code libraries are built into the application and available offline.

Does Robot Structural Analysis work with Revit?

Yes. Robot Structural Analysis includes a bidirectional link with Autodesk Revit. Structural models import from Revit with automatic dead load calculation, and analysis results export back to Revit to maintain coordination between structural analysis and BIM documentation.

Is it good for seismic design?

Yes. Robot Structural Analysis supports modal analysis, response spectrum analysis, time-history analysis, and pushover simulation for seismic design. It verifies structures against code-based seismic requirements and supports base isolation system modeling for high-seismic-zone projects.

What does RSA Pro stand for?

RSA Pro is the common abbreviation for Autodesk Robot Structural Analysis Professional — the full commercial name of the product. It is also referred to simply as "Robot Structural Analysis" or "Robot" in structural engineering practice.

What is the difference between Robot Structural Analysis and ETABS?

Robot Structural Analysis covers a broader range of structure types including bridges and industrial facilities, includes built-in CFD wind load simulation, and offers a native bidirectional Revit link. ETABS is optimized specifically for building structures and high-rise design. Robot is available as a one-time purchase; ETABS is subscription-only.
