CSI ETABS Ultimate

About CSI ETABS Ultimate

ETABS is built around the way buildings actually get designed. The model is organised by storey rather than as a loose collection of members, so a typical floor is defined once and repeated up the building, and a change to that floor propagates everywhere it appears. For multi-storey work that structure alone removes an enormous amount of repetitive modelling.

The analysis side covers what building design requires. Static and dynamic analysis, response spectrum and time history, P-Delta and buckling, staged construction and nonlinear behaviour are all available, with automatic lateral load generation for wind and seismic against the selected code. Floor systems, shear walls, ramps and slabs are modelled as objects rather than as raw meshes.

Design follows the analysis inside the same model. Steel frame, concrete frame, composite beam, shear wall and slab design all run against the chosen code, with results reported per member and the governing combination identified. Sections can be optimised automatically and the analysis rerun until the design converges.

The output end handles what has to leave the office. Detailed drawings, schedules and quantity takeoffs generate from the designed model, reports assemble with the tables and diagrams an approving engineer expects, and the model exchanges with modelling and detailing packages so the structural work lands in the wider building model.

What is included in this build

Changed in version 22.7.0.4095

• Faster solver on models with high storey counts
• Additional design code revisions in the code set
• Improved meshing of irregular floor openings
• Better staged construction handling on tall structures
• Report output tidied for very long member schedules

Installation walkthrough

These steps assume a clean machine. If a previous release of the same application is present, deal with that first, since an overlapping install is the most common cause of a setup that stops halfway.

1. Disable real-time protection until the install has finished.
2. Extract the archive to a short path with no spaces.
3. Install the bundled runtime prerequisites when setup offers them.
4. Run setup as administrator and choose the design code region.
5. Reboot once before opening the first model.
