Get powerful, intuitive analysis
GSA Analysis gives engineers a highly intuitive nonlinear analysis software tool to realise the potential of their design,
whatever and wherever it is. This structural analysis software program is used across the globe on all manner of projects.
The essential engineering analysis tool
From beams to tall buildings, from simple structures to the most complex, GSA Analysis is the
program to help solve engineering problems.
With this software, engineers can easily carry out 3-D linear, P-delta, non-linear static analysis and more.
They can also carry out Modal and Ritz vibration analyses with or without the stiffening effects of loads,
including seismic and time-history assessment.
Highly intuitive editing makes for rapid model creation and sculpting of models.
Because the program is built to work with Revit Structure, users can export from Revit to GSA Analysis and update Revit
from their GSA Analysis models. They can even create new Revit models from GSA.
Originally developed in-house at Arup, GSA Analysis was used on prestigious projects such as Khalifa Stadium in Doha
and the Angel of the North in the UK. The software is now the program of choice for leading engineers.
Analyse structures with large (and indeed very large) deflections, plastic yielding of materials, snap-through, sway effects,
and more. GSA Analysis uses the dynamic relaxation method to enable you to analyse structures that other programs will not touch.
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,
With staged analysis you can assess the model at any stage in construction, remove elements, and change sections and restraints,
all coordinated in a single model.
