Description
Structural design and analysis software
Comprehensive design and analysis software
The intuitive structure design software allows engineers to design structural models with 1D, 2D and 3D finite elements, however large or complex. With inbuilt form finding routines and API links to your own programs, GSA Suite allows you to create the optimum structure. It will then design your steelwork and concrete reinforcement, check for seismic response and human induced vibration, calculate buckling capacities, and can even tell you where you have made mistakes in your model.
As engineers and architects continue to push boundaries with new creations, GSA offers a quick, accurate, and affordable solution for even the most advanced project. GSA has supported a wide range of projects worldwide, including the Swiss Re (London), CCTV Headquarters (Beijing) and Las Vegas High Roller, and has global recognition as one of the most complete packages for structural engineers.
GSA’s easy-to-use interface and customer support mean you’ll be creating and sculpting models in no time. A spreadsheet-friendly file format and smooth interaction with other tools make this software the perfect choice. GSA is BIM (Building Information Modelling) compatible, and also designed to connect with a range of other leading software packages, including Autodesk Revit.
GSA Suite is our most comprehensive structural package, offering all of the GSA variant features, along with form finding and fabric analysis tools for tensile and gridshell structures.

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.
Analysis and Design: GSA includes several solvers, including:
- Form finding for lightweight structures
- Tension-only fabric material models
- Steel member and concrete slab design
- Footfall analysis for human-induced vibration
- Bridge load optimisation
- 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, harmonic and periodic vibrations, and human-induced vibrations
- Soil structure interaction for rafts and piled structures
- Diagnostic analyses for resolving modelling problems
Using a choice of form-finding methods, GSA will determine the optimum geometry for your arch, cable net, grid shell, or fabric structure.
GSA will find the lightest, shallowest, cheapest, or most environmentally friendly steel beam section to carry the load, and work out the ideal quantity of reinforcement in your concrete slabs and walls.
Output: Output forces, moments, deformed geometry, and other results in graphical views, tables, and graphs. Export analysis models from the structural analysis software to LS DYNA, model changes to Revit, or text and numbers to Office documents.
