Description
Structural design and analysis software
Perform day to day analysis and solve complex engineering problems
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.
How GSA Analysis Works
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:
- Matrix-based stiffness method for static and p-delta analyses
- Dynamic relaxation and explicit solvers for nonlinear static and dynamic problems
- Eigenvector solvers for modal vibration and buckling analyses
- Dynamic response analyses for seismic response spectrum or time history, plus harmonic and periodic vibrations
- Soil structure interaction for rafts and piled structures
- Diagnostic analyses for resolving modelling problems
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.</
Key Features & Benefits
- Produce fast and accurate results from the simplest beam to the most complex building, all within the one environment
- Work with 0, 1, 2, & 3D elements to model just what you need to analyse
- Integration with Autodesk’s Revit Structure and other BIM software will ensure high integrity of model transfer and accurate model coordination
- Analyses include Linear and Nonlinear Static, Dynamic, and Buckling analyses, plus Dynamic Response, Soil-Structure Interaction, and Analysis stages
