From beams to tall buildings, from simple structures to the most complex, GSA Analysis is the structural engineering analysis program to help solve engineering problems.
With this software, you can efficiently and effectively carry out 3D linear, P-delta, non-linear static analysis and much more. You can also carry out Modal and Ritz vibration analysis with or without the stiffening effects of loads, including seismic and time-history assessment. GSA Analysis also includes soil-structure interaction using either Oasys Pdisp engine or 3D soil brick elements.
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. Additionally, you can export from Revit to GSA Analysis and update Revit from your GSA Analysis models. You can even create new Revit models from GSA.
Analysis: GSA includes several solvers, including:
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.</

API improvements – New features include direct objects for Members that lead to faster access and productive code development, expansion of existing objects, and the ability to run automated design from the API using the new Design Task functionality.
Nonlinear analysis
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.
Buckling analysis
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 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.
Stages
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.
P-delta Analysis
GSA offers a wide range of structural analysis types
Analysis features:
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
Overview
GSA combines GSA structural model with a 3D brick or Pdisp soil model to calculate the soil structure interaction.
Find how your structure interacts with the ground for the optimum foundation design
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
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

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.

Keeping your software licences maintained gives you full access to technical support (telephone, email and web based) and ensures that your software is kept up-to-date with free downloadable updates. Maintenance is only available to existing licences and lasts 12 months. It is highly recommended that you keep your software licences maintained. Maintenance duration will be calculated from the date of expiry of the previous maintenance/initial warranty. If you are purchasing maintenance for licences that have been unmaintained for longer than 12 months please contact us in order to renew.
"I still have yet to find a structural analysis software that can compare with GSA in both capabilities as well as user interface/input/output etc."
