GSA Bridge has proved its worth as a key piece of bridge engineering software on award-winning projects such as the Infinity Footbridge, the Falkirk Wheel, and the Gatwick Air Bridge.
Part of the GSA suite of programs, GSA Bridge is the perfect bridge design software for busy bridge designers. This easy-to-use bridge analysis software automatically sifts through the multiplicity of possible moving loads to find the crucial loads for your structure.
GSA Bridge will also design the steel beams and slab rebar for you to a variety of national and international codes, determining what is needed to carry the load.
As designs become more efficient, the resulting structures get lighter and more responsive to human induced vibrations. GSA Bridge thus includes the advanced footfall module and is the leading program available for vertical footfall analysis on any structure.
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:
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 to LS DYNA, model changes to Revit, or text and numbers to Office documents.

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.
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 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.

Steel member design features include:
Analyse structures with large and very large deflections, plastic yielding of materials, snap-through, sway effects, and more. GSA Analysis uses the dynamic relaxation method to analyse structures that are too large and complex for other programmes.
GSA Analysis 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 Analysis 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 Analysis 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.
With staged analysis you can assess the model at any stage in construction, remove elements, and change sections and restraints, coordinated in a single model.
GSA offers a wide range of structural analysis types
Analysis stage specification:
When an analysis is requested the data are checked for inter-module consistency. If errors are detected, a report is prepared and the program returns to the data editing options; if not, the program proceeds with the analysis with progress being reported to the screen throughout
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
Sculpt enables all structural geometry to be rapidly generated and edited on the screen using a cursor controlled by a mouse. Dynamic viewing makes it possible to adjust the model as required
When the structure is complete, all loading may be similarly generated and displayed diagrammatically. Structures of complexity varying from simple to large skeletal frame models can be generated and complex 2D element meshes can be generated using the automatic mesh generation facilities
The alternative spreadsheet method incorporates many useful features for the generation and copying of numerical data. Text input is normally specified by selection from a list of available items rather than by entering numeric codes.
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
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 has a highly responsive interface which facilitates an intuitive understanding of model behavior. For example, it allows for smooth rotation and magnification of the model while viewing enveloped results, allowing for effective post processing within the program itself. Many other structural analysis programs move sluggishly or not at all when results are displayed, and full post-processing of results must be done in other programs to be effective"
