From beams to tall buildings, from simple structures to the most complex, GSA Analysis is the structural engineering analysis program to help solve engineering problems.

With this software, you can efficiently and effectively carry out 3D linear, P-delta, non-linear static analysis and much more. You can also carry out Modal and Ritz vibration analysis with or without the stiffening effects of loads, including seismic and time-history assessment. GSA Analysis also includes soil-structure interaction using either Oasys Pdisp engine or 3D soil brick elements.

How GSA Analysis Works

Input: Create structural finite element analysis models using CAD and BIM links, directly in the table or graphical views, or using your own scripts via the Application Programming Interface. Assign linear and nonlinear materials to a variety of element types, whether beams from catalogues, standard shapes, profiled slabs, or your own special requirements. Add static, dynamic, prestress, or thermal loads and analyse the effect. Additionally, you can export from Revit to GSA Analysis and update Revit from your GSA Analysis models. You can even create new Revit models from GSA.

Analysis: GSA includes several solvers, including:

  • Matrix-based stiffness method for static and p-delta analyses
  • Dynamic relaxation and explicit solvers for nonlinear static and dynamic problems
  • Eigenvector solvers for modal vibration and buckling analyses
  • Dynamic response analyses for seismic response spectrum or time history, plus harmonic and periodic vibrations
  • Soil structure interaction for rafts and piled structures
  • Diagnostic analyses for resolving modelling problems

Output: Output forces, moments, deformed geometry, and other results in graphical views, tables, and graphs. Export analysis models to LS DYNA, model changes to Revit, or text and numbers to Office documents.</

Key Features & Benefits

  1. Produce fast and accurate results from the simplest beam to the most complex building, all within the one environment
  2. Work with 0, 1, 2, & 3D elements to model just what you need to analyse
  3. Integration with Autodesk’s Revit Structure and other BIM software will ensure high integrity of model transfer and accurate model coordination
  4. Analyses include Linear and Nonlinear Static, Dynamic, and Buckling analyses, plus Dynamic Response, Soil-Structure Interaction, and Analysis stages

Additional information

Select your licence

Standalone, Network Floating

I would like to

Buy, Rent – 12 months, Rent – 6 months, Rent – 3 months, Rent – 1 month, 12 months maintenance (existing users only)

What should I choose?

Standalone Licences are locked to an individual machine but transferrable by the user to another machine. Ideal for single users.

Network Floating Licences can be activated on any number of machines, however you can only concurrently use the number of licences that you have purchased. Ideal for users requiring more flexibility or when working as part of a team.

Buying a licence will allow you the right to use that version of the software indefinitely. It includes a complimentary 12 months of maintenance (technical support and access to software updates).

Renting the software enables you to use the software with full technical support for the defined duration.

Keeping your software licences maintained gives you full access to technical support (telephone, email and web based) and ensures that your software is kept up-to-date with free downloadable updates. Maintenance is only available to existing licences and lasts 12 months. It is highly recommended that you keep your software licences maintained. Maintenance duration will be calculated from the date of expiry of the previous maintenance/initial warranty. If you are purchasing maintenance for licences that have been unmaintained for longer than 12 months please contact us in order to renew.

Note: complimentary 12 months support and maintenance is included when purchasing all products.
