Description
Structural design and analysis software
Oasys GSA
With Oasys GSA, you can analyse the structural design of any structure which needs to be iterated through many cycles of geometry definition, internal force analysis and code design. GSA gives engineers a versatile analysis and design software that integrates well within traditional and parametric workflows.

Why should I buy it?
Engineers who analyse and design anything from small structures to complex buildings use Oasys GSA.
With a wide range of analysis options including a model debugging stability analysis, modal analysis, linear buckling, footfall vibration analysis, explicit nonlinear analysis and form-finding capabilities to meet the demands of any project, GSA allows the user to manipulate and check the model. Bidirectional interoperability with many industry-standard software packages including Revit and Grasshopper allows the software to work seamlessly with traditional and parametric workflows. APIs connect to developer’s scripts. With GSA, versatile design capabilities such as slab bending and axial reinforcement can be calculated for any geometric shape (even curved slabs) with rebar oriented at any angle in the plane of the slab, or steel design checks (including automatic unbraced length calculations) and optimisation can be carried out for a large variety of section profiles and codes. There is a customisable set of saved graphical outputs that can be directed printed to calculation packages.

| Analysis | Building | Bridge | Suite | ||
|---|---|---|---|---|---|
| User Interface | |||||
| Customisable Graphic Views with Flexible Contouring and Labeling | |||||
|
Flexible graphic views to display whatever information you want in whatever format you want. GSA can create contours for any parameter or result in the model and allow you to customize the display based on what you want to see in the model. |
|||||
| Versatile and Transparent Meshing | |||||
|
Draw or import any geometry and GSA will create a suitable analytical mesh. Viewing and manipulation of the meshed geometry is possible before analysis so that you can have complete confidence in your model. |
|||||
| Flexible Tabular and Graphical Inputs | |||||
|
Create and manipulate your model geometry and loads with graphical and tabular inputs. |
|||||
| Grasshopper Plugin | |||||
|
Parametrically create, edit, and optimize your models with GSA's Grasshopper plugins. |
|||||

|
GSA offers bidirectional interoperability with many industry-standard software packages including Revit, AutoCAD and .ifc files. Exports also available to IDEAStatiCa, LS DYNA and AdSec. |
|||||
| Application Programming Interface | |||||
|
For advanced users, GSA's API expands the realm of possibilities by allowing the user to create scripts using a wider range of languages to interact with the program. Use your own code or third-party programs to create, edit and optimize your GSA model through either the .NET or COM API. |
