ETABS
Integrated building analysis and design software from CSI, purpose-built for multi-storey and high-rise structures — from initial 3D modelling through to code-based design, powered by the SAPFire analysis engine.
One model, from concept to code-checked design.
ETABS combines 3D object-based modelling, analysis, and design in a single environment built specifically around how buildings are structured.
3D object-based modelling
Model floors, walls, and frames the way buildings are actually structured — not as generic finite elements.
SAPFire analysis engine
Multiple 64-bit solvers with eigen and Ritz analysis, refined over decades of structural engineering use.
Response spectrum & time history
Seismic and dynamic analysis capabilities built in for code-compliant design in earthquake regions.
P-Delta & staged construction
Account for second-order effects and model how a structure is actually built up in stages.
Code-based design checks
Automated design and checking against major international structural design codes.
Interoperability with SAFE
Import and export models, loads, and displacement fields directly between ETABS and SAFE.
ETABS is available in three levels.
Plus, Nonlinear, and Ultimate share the same interface and workflow — each level adds deeper analysis capability on top of the last.
ETABS Plus
- SAPFire analysis engine
- Response spectrum & time history analysis
- P-Delta analysis
- Single-stage construction sequencing
ETABS Nonlinear
- Everything in Plus
- Buckling & pushover analysis
- Multi-stage staged construction
- Nonlinear analysis (Fast Nonlinear Analysis method)
ETABS Ultimate
- Everything in Nonlinear
- Time-dependent stiffness, creep & shrinkage
- Full advanced analysis & design capability
- Best for complex, high-rise, or nonlinear-critical projects

Processor
Minimum: Intel Pentium 4 or AMD Athlon 64
Recommended: 9th generation Intel Core i5/i7/i9, AMD Ryzen 5/7/9 with Zen 2 architecture, or better desktop CPU
A 64-bit CPU is required.
Operating System
Microsoft® Windows 8.1 or Microsoft® Windows 10
64-bit processor
Video Card
Minimum: Supporting 1024 by 768 resolution and 16-bit colors for standard (GDI+) graphics mode
Recommended: Discrete video card with NVIDIA GPU or equivalent and dedicated graphics RAM (512 MB or larger) for DirectX graphics mode. The card must be DirectX 11 compatible.
DirectX graphics mode fully utilises the hardware acceleration provided by a GPU and dedicated graphics RAM. For better graphics quality in terms of anti-aliasing and line thickness, the device raster drawing capabilities should support legacy depth bias.
Memory
Minimum: 8 GB RAM
The problem size that can be solved, and the speed of solution and response recovery, increase considerably with more RAM.
Disk Space
6 GB to install the software.
Additional space will be required for running and storing model files and analysis results, depending on the size of the models.
Recommended: 500 GB or larger PCIe Solid State Drive (SSD). External and network drives are not recommended.
