CSI ETABS Ultimate

Building analysis and design in one integrated model, covering the framing, the floors, the walls, and the foundations, with code checking and drawing output for the whole structure.

Overview

What this release is

ETABS is written specifically for buildings rather than for structures in general, and every part of the interface reflects that. The model is organised by storey, framing is drawn on plans that understand what a floor level is, and repeated levels are defined once and applied through the height. On a twenty storey tower this saves days of modelling compared with a general purpose analysis package.

The analysis capability underneath is anything but simplified. Nonlinear behaviour, staged construction sequencing, response spectrum and time history dynamic analysis, buckling, and the performance based pushover procedures are all present, with the solver built to handle the very large element counts a full building model generates.

Seismic work is where the package is strongest. Automatic lateral load generation follows the major codes, diaphragm behaviour is modelled correctly rather than assumed, storey drift and irregularity checks are computed automatically, and the results present in the form that a review authority expects to see them. Wind load generation follows the same pattern.

Design runs from the same model rather than from an export. Steel members are sized and checked, concrete beams and columns are designed with reinforcement detailing, shear walls are handled with proper boundary element checks, and composite floor systems are designed with the framing. Foundation loads are extracted directly for the substructure design.

Output includes detailed calculation reports showing the intermediate values, drawing production for the designed members, and export to the detailing and documentation formats that the rest of the project runs on. This build installs the complete Ultimate configuration with every design code and every analysis module enabled.

Feature set

What you get

Building oriented modelling

Storey based organisation with repeated levels defined once and applied through the height.

Seismic analysis

Automatic lateral load generation, correct diaphragm modelling, and drift and irregularity checks against the major codes.

Nonlinear and staged

Nonlinear behaviour, construction sequencing, time history, buckling, and performance based pushover procedures.

Integrated design

Steel, concrete, shear wall, and composite floor design running from the analysis model without an export step.

Detailing output

Reinforcement detailing and drawing production for designed members, plus foundation load extraction.

Full code coverage

Every design code library included and switchable without remodelling the structure.

Changes in this build

What changed

Faster solving on models with very high element counts through improved memory handling
Updated seismic code provisions across several national standards
Shear wall design rebuilt with clearer boundary element reporting
Improved staged construction setup with sequence templates
Fixed the diaphragm assignment that could be lost when a storey was duplicated

Installation

How to install it

Disable real time protection before extracting and keep it off until the licensing step is complete.
Extract to a short path on a drive with at least 15 GB free.
Run the installer as administrator and install every design module.
Apply the included licensing configuration before the first launch.
Block outbound access for the executables so the licence state is not revalidated.

Questions

Before you start

How does it differ from a general analysis package?

The model is organised around storeys and building systems, which removes an enormous amount of repetitive modelling on multi level structures.

Is this the full Ultimate configuration?

Yes. Every analysis module and every design code library is included and enabled.

Can models be exchanged with detailing software?

Yes, through the standard structural exchange formats, with member sizes and connections carried across.

Does it need a licence server?

Not in this configuration. The licensing step removes the server dependency.
