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.
Download BrochureInput: 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:
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.

Finding the correct geometry and prestress forces for tension only structures such as fabric structures, fabric roofs and cable nets is crucial: mistakes lead to wrinkles, flapping, and ponding problems. While some programs will generate geometry that looks nice, GSA will find the geometry that is right. GSA gives you the control to offset the effects of fabric to cable prestress, radial to circumferential stresses, and more.
GSA also enables you to generate the organic geometry for compression-only structures such as grid shells and slender arches.
GSA uses its powerful dynamic relaxation non-linear solver to form find using soap film, force density and structural properties to find the optimum structural arrangement, and then analyse and design it to all the serviceability and ultimate loads.
Form-finding and fabric analysis – Further Detail
Dynamic relaxation method with the following options
Fabric analysis
As designs become more efficient, the resulting structures get lighter and more responsive to human induced vibrations. This means that footfall induced vibration is becoming an important serviceability design requirement for office and residential buildings, foot bridges and staircases: it is an essential requirement for demanding situations such as hospitals, footbridges and laboratories.
GSA enables you to find the footfall response over the whole structure, with full contour plots and detailed graphs showing exactly where the satisfactory and problem areas are. You can thus explore cost-effective design solutions and advise you client on how their structure will respond to human induced vibration.
Footfall analysis
Sensitivity to vibration is becoming increasingly significant as advances in structural design result in lighter structures; the lighter the structure the more sensitive it is to induced vibration.
Footfall analysis methods
GSA is perfect for busy foundation designers as it enables you to analyse how your structure interacts with the ground for optimum design. This easy-to-use software combines non-linear structural and geotechnical models to calculate accurate settlements, soil pressures, bending moments and other structural stresses in a fraction of the time.
GSA adds Oasys Pdisp’s soil pressure displacement engine to GSA Suite’s finite element analysis. The structure then interacts with the ground via piles, rafts or pads so they both work together to carry the load, whatever the structure, whatever the soil. GSA also integrates with Pdisp, importing soil models and exports results for further geotechnical investigation.
Calculate the reinforcement requirements for concrete slabs and walls to international design codes:
Results are available in various forms, including numeric utilization ratios and calculations as rich text. The different forms of result available mean that the user can avoid information overload, but can still audit the calculations at a very basic level when appropriate. Utilization ratios can be plotted (contoured) on the model just like any other numeric result, so enabling rapid understanding of which parts of a structure are overstressed or are over designed. Calculation results are marked up in colour to draw attention to problems and important results within the calculations.
Overview
GSA combines GSA structural model with a 3D brick or Pdisp soil model to calculate the soil structure interaction.

Raft is perfect for busy foundation designers. This easy-to-use software combines non-linear structural and geotechnical models to calculate accurate settlements, soil pressures, bending moments and other structural stresses in a fraction of the time.
Features
Nonlinear analysis
Analyse structures with large deflections, plastic yielding of materials, snap-through, sway effects, and more. GSA uses the dynamic relaxation method to enable you to analyse structures that other programs will not touch.
Buckling
GSA enables you to calculate the buckling load factors on a range of structures, from complex frames to shell structures and lateral torsional buckling of plate girders. It also includes non-linear buckling effects so you can plot the deflections of columns and struts against load to accurately assess safety factors.
Dynamic analysis and response
GSA includes both modal analysis for calculation of the natural dynamic frequencies of your structure and Ritz analysis specially designed for seismic response calculations. You can choose to include axial load effects to change stiffnesses in both these methods.
Following on from the modal or Ritz analysis, GSA enables you to calculate the structural response using a number of dynamic post processors, including seismic response to multiple international codes, linear time history, harmonic loads for vibrating machinery, and more.
Other Analysis Types include:
Automated bridge loading to:
Path and vehicle loading to
The API enables GSA to be driven from a spreadsheet macro or other external program. In addition, the command line interface enables GSA to be driven from batch files.
GSA includes a bi-directional link between GSA & Revit 2014, 2015, 2018 and 2019, Revit Structure 2013 & Revit Structure 2012. With this Revit users can transfer model information between Revit and GSA with minimal loss of data.
Data from tables can be transferred to and from spreadsheets using the standard cut and paste facilities. The GWA file (ASCII data file) is written as a tab-separated file to facilitate input into spreadsheet programs
Import options
Export options
For regular structures, a Data Generation wizard will allow the user to specify the structure in terms of few key parameters and automatically generate the model data. For more complex structures structural geometry and loading data may be input through either the graphical data generator (“Sculpt”) or a more traditional spreadsheet format, which enables all structural geometry to be rapidly generated and edited.
When the structure is complete, all loading may be similarly generated and displayed diagrammatically.

The graphics facility in GSA is designed to feel spontaneous in response to the commands of the user. Various single key commands have the effect of producing standard views, adjusting the orientation, scale and content of the drawn structure, windowing, zooming, labelling and annotating the display. Dynamic viewing and animation of results provide powerful tools to aid you in understanding the behaviour of the structure. Graphical output can be sent to a printer or in DXF format for exporting directly to CAD systems.
Hong Kong engineers get go ahead to use GSA 10
Oasys GSA 10 has been pre-approved for use in calculations for steel member design used to support applications for submissions to the Hong Kong government authorities.
As with all such pre-approvals, it still leaves the onus on engineers to check that the program is applicable, that its assumptions are valid for each project and that it is correctly configured. So the pre-approval of software developed by the trusted Oasys team will be welcome to engineers working throughout the Territory.
See the list of pre-accepted computer programs for full details.
Following several requests from customers we have developed a small utility to allow those customers who have multiple variants of GSA shared licences to easily swap between them.
5. Select the variant you wish to run and then open GSA. Each time you open GSA after this, it will run the last activated variant until you run Oasys Key Switcher again and select another variant.
GSA Building is part of the Oasys General Structural Engineering suite and combines steel and concrete design, footfall, and soil-structure interaction analysis in the same building design software package. With this intuitive software, you can design structural models with skeletal frames and two-dimensional finite elements, enabling you to design and analyse even the most complex buildings.
