GSA Building

Designed by engineers for engineers, GSA Building has met the demands of projects like 30 St Mary Axe in London, the National Assembly for Wales in Cardiff, Marina Bay Sands in Singapore, and the CCTV building in Beijing.

GSA Building combines steel and concrete design, footfall and soil-structure interaction analysis features within the same software package. With this intuitive software, you can design structural models with a full range of 1D, 2D and 3D elements, to design and analyse even the most complex buildings.

GSA Analysis

GSA Analysis is a highly intuitive tool. Perform day-to-day analysis and solve complex engineering problems within the same platform.

GSA Analysis is developed around a graphical environment, which means more time can be spent on other parts of the design and analysis. The integration with Autodesk’s Revit Structure and other advanced modelling software ensures easy model transfers and accurate model coordination.

GSA Suite

GSA Suite is our most comprehensive package, offering all of the above with form finding and fabric analysis for tensile and gridshell structures in a single, straightforward package.

GSA Suite allows you to design structural models with 1D, 2D, and 3D finite elements, use footfall analysis to measure the responsiveness of human induced vibration, and form finding to ensure the correct forces and pre-tension within fabric structures.

As engineers and architects push the boundaries with new creations, GSA offers a solution which is quick, accurate, and recognised globally as one of the most complete packages for structural engineers.

GSA Bridge

The perfect tool for busy bridge designers, GSA Bridge automates the optimisation of bridge loads (such as vehicle and lane loading) to a variety of international codes, as well as checking for pedestrian footfall vibration.

Simulate advanced bridge engineering problems with accurate tools developed by the producers of the design criteria. One of the only packages to include the vertical footfall analysis feature, with data available in rich text or spreadsheet format, it fits seamlessly with other tools on your desktop.
