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.

Redesigned and streamlined user interface – Quick access to popular tasks with customisable panes and toolbars.
New beam section – Improve interoperability by allowing you to define any section once and then being able to reuse it within any Oasys software program.
New Beam Section
Materials – Define design grade materials at the analysis and model building stage. Build user-defined materials.
Grid loading – Work with 1D or 2D elements, allowing patch, line, and bridge loads on meshes.
IFC import & export with GsRevit – Interchange data between a variety of BIM friendly platforms with GSA 9.0’s new IFC import and export. As well as new Revit integrations allowing you to map entities with ease.
Explicit solver – A new analysis solver for dealing with short time-span, high frequency dynamic non-linear situations has been implemented along with improved load curves functionality.
Seismic analysis – New advanced seismic analysis features include response spectrum analysis with improved display, tools and combinations.
3D solid elements & soil structure interaction – Now includes 3D solid (brick) elements allowing a wide range of structural properties to be simulated. New Contact and Damper element types have been introduced to model dynamic problems such as modelling contact between different elements.
Brick Element: Diagram – Surface Contour – Filled Contour
Raft Analysis – The Raft Analysis feature is now available in all GSA variations. This analysis type is perfect for busy foundation designers. This easy-to-use feature 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.
Design improvements – Design materials have improved functionality and create more consistent models.
Steel member design – Improved member design that provides analysis releases along with in-depth functionality options with instant results in report view.

Member libraries
New chart views, reporting and graphics – In addition to the instant report view results, chart view functionality is improved with easy updating and exporting of curves. Graphics have been improved making your 3D model and 2d graphic look even better.
New Chart Views
Improved Graphics
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.

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.
