ETABS v23.3.0 – Latest 2026 Update Officially Released

ETABS v23.3.0 is the latest 2026 update CSI, delivering improved stability, faster model processing and better compatibility with modern structural design workflows. The version adds slab design according to CSA A23.3:2024, automatic wind-load calculation under KDS 41 12 00:2022, SQLite data support, .NET 10 API compatibility and several enhancements to modelling, output display and the user interface.

CSI has officially released ETABS v23.3.0 – the latest intermediate update following the success of version v23.2.0. With continuous improvements, ETABS continues to affirm its position as one of the world’s leading software solutions for the modelling, analysis and design of high-rise building structures.

ETABS – A Standard Solution for Modern Structures

ETABS has long been an indispensable tool for structural engineers worldwide. With the ability to handle complex tasks ranging geometric modelling and dynamic analysis to detailed design in accordance with international and Vietnamese standards, including TCVN, ETABS helps optimise the design process while ensuring the highest levels of accuracy and structural safety.

Why Should You Upgrade to ETABS v23.3.0?

ETABS v23.3.0 is an important update released by CSI to provide users with improved stability and optimised performance. Upgrading to the latest version helps engineers:

• Optimise performance: Take advantage of the latest improvements in analysis algorithms and model processing, enabling faster and smoother workflows.
• Ensure compatibility: Maintain seamless data exchange between platforms and with partners using the latest software versions.
• Experience new technologies: ETABS v23.3.0 fully inherits the innovations introduced across the v23 ecosystem, including the integration of the latest design standards, such as TCVN 5574:2018, flexible Cloud Licensing technology for remote working and powerful BIM data connectivity.

Key New Features in ETABS v23.3.0

For structural design, ETABS v23.3.0 adds support for the design of conventional reinforced concrete and post-tensioned concrete slabs in accordance with the Canadian standard CSA A23.3:2024.

For loading functions, ETABS v23.3.0 adds the automatic wind-load standard KDS 41 12 00:2022. This includes the automatic calculation of gust-effect factors for rigid and flexible structures based on the dominant mode shape, with options to include crosswind and torsional wind effects where appropriate.

Data import and export have also been improved. ETABS v23.3.0 now supports tabular data in SQLite format.

For structural modelling, a new Storey Inertia Forces table has been added. It provides inertia forces at each storey for modal and response-spectrum load cases, eliminating the need to calculate these values using section cuts as previously required.

Load calculations during the creation of element models have been improved to enhance performance.

For programming through the Application Programming Interface – API, ETABS v23.3.0 now supports API client applications targeting .NET 10 when accessing the API through COM.

Output and display functions have also been improved. In ETABS v23.3.0, the program’s behaviour for section cuts defined by groups has been updated. When a section cut includes an automatically meshed area object and all of its defining joints, the section cut now includes all internal elements and program-generated joints associated with that automatically meshed area. This change only affects cases in which section cuts are used to calculate internal joint forces, such as inertia forces or applied acceleration forces. It does not affect section cuts defined by a cutting plane or section cuts that include only some of the joints within the area.

The user interface has also been improved. Load cases and load combinations are now arranged alphabetically in all applicable list boxes throughout the program.
