Overview
ETABS is built specifically for buildings rather than structures in general, and the whole environment reflects that. Models are organised by storey, floor systems are objects rather than collections of members, and results come back in the terms a building engineer works in: storey drift, storey shear, overturning, diaphragm forces and irregularity checks.
That focus makes the modelling fast. Similar storeys are defined once and replicated, grids drive the layout, and templates generate a full frame in a few dialogs. Loads follow the same logic: automatic seismic and wind generation to the major regional codes, pattern live loading, and load combinations built automatically from the selected code rather than typed in by hand.
The Ultimate configuration includes the full analysis and design range. Linear and non-linear static and dynamic analysis, pushover, direct integration time history, staged construction, cracked section behaviour, and design for steel frames, concrete frames, shear walls, composite beams, columns and slabs, all against the international code set. Detailed drawings and schedules can be generated from the designed model.
What it does well
Building specific modelling
Storey based organisation, similar storey replication, grid driven layout and floor systems as first class objects.
Automatic load generation
Seismic and wind loads generated to the major regional codes, with combinations built automatically from the chosen standard.
Full analysis range
Static and dynamic, linear and non-linear, pushover, time history, staged construction and cracked section analysis in one solver.
Integrated design
Steel and concrete frames, shear walls, composite beams, columns and slabs designed against international codes off the same model.
Results in building terms
Storey drift, shear and overturning, diaphragm forces and irregularity checks presented per storey rather than per element.
Changes in this build
- Solver rebuilt for better scaling across high core count machines.
- Seismic code modules updated for recent regional amendments.
- Shear wall design output reworked with clearer reinforcement schedules.
- Improved import from building information models with mapping controls.
- Fixed a meshing issue on slabs with irregular openings.

Installation
- Extract the archive to a local drive.
- Remove any earlier release of the same application.
- Run setup and install the prerequisite runtimes when prompted.
- Apply the included configuration step before the first launch.
- Open a sample model and run an analysis to confirm the solver works.
Before you start
Non-linear analysis writes very large scratch files, keep the working folder on a fast disk with room.
Set the design code before modelling, changing it later regenerates every combination.
Models from a much older release should be opened and saved forward once.
Questions about this title
Does it generate seismic loads?
Yes, automatically to the major regional codes, with combinations built to match.
Can it design shear walls?
Yes, along with frames, composite beams, columns and slabs.
Does it do non-linear analysis?
Yes, pushover, time history and staged construction are all in the Ultimate configuration.
Are sample models included?
Yes, with the documentation set.
About this listing
This entry was checked on a clean install of Windows 10 / 11 (64-bit) before it was published, and it is rechecked whenever the package is rebuilt. The figures on this page come from the site index rather than from the publisher, so the download count is what people here have actually pulled.
If a mirror stops answering, use the contact form and it gets replaced. Reports about a specific title are handled faster than general messages because they name the file, the mirror and the point at which the transfer stopped.
Requests for a different version, a different language build or an older release go on the requests page. Older versions of a title are usually still held even when only the current one is listed.
