CSI ETABS 22.4.0

Computers and Structures, Inc. (CSI) has released ETABS 22.4.0. This release includes improvements for large displacement analysis (for link elements). Also included are design improvements to Eurocode composite beams. Concrete users will see improved slenderness checks and reporting for walls (ACI 318-19 and Eurocode 2) and columns (ACI 318-19 and AS 3600-18). Finally, there are improvements in the API functions for exporting and importing of the model and an updated version of the CSI Analysis Reference Manual.

ETABS 22.4.0 Enhancements - Date: 23-Dec-2024

Analysis
- Greater control over link-elements in models with large displacements has been added. This new behavior applies to nonlinear static, direct-integration, and staged-construction load cases where the geometric nonlinearity parameter has been set to P-Delta plus Large Displacements.
Steel Design
- ETABS can now design composite beams with large web openings per the provisions of SCI Publication 355 and of Eurocode 3 - Design of Steel Structures - Part 1-13. This includes beams with a regular I-section and discrete openings as well as castellated and cellular beams.
Shear Wall Design
- ACI 318-19 slenderness checks for wall buckling in the out-of-plane direction are now performed for walls in a single plane (i.e. 2D pier) for uniform and general reinforcing options.
- ACI 318-19 shear wall design now considers the Seismic Design Category (SDC) when determining whether a wall shear capacity check is required.
Output and Display
- Eurocode 2 shear wall design, pier output has been improved to include additional design parameters such as amplified shear (Vu,amplified) for seismic piers, pier shear capacity (Vrd) and pier maximum allowable shear (Vrdc,max).
Concrete Design
- ACI 318-19 and AS 3600-2018 concrete frame design output has been enhanced with additional parameters now reported for column slenderness design. For ACI 318-19 code, these parameters are beta_dns, (EI)eff and Pc. For AS 3600-2018 code, these parameters are beta_d, φ*Mub and Pc.
Documentation
- The CSI Analysis Reference Manual has been updated to include content for minor existing features that were previously only described in the Help, as well as for style and improved ability to search within the PDF file.
Application Programming Interface (API)
- New API functions have been added to allow export and import of the model text file (.e2k) or the database tables to Excel, Access, Text, or XML file.


ETABS is an engineering software product that caters to multi-story building analysis and design. Modeling tools and templates, code-based load prescriptions, analysis methods and solution techniques, all coordinate with the grid-like geometry unique to this class of structure. Basic or advanced systems under static or dynamic conditions may be evaluated using ETABS. For a sophisticated assessment of seismic performance, modal and direct-integration time-history analyses may couple with P-Delta and Large Displacement effects. Nonlinear links and concentrated PMM or fiber hinges may capture material nonlinearity under monotonic or hysteretic behavior. Intuitive and integrated features make applications of any complexity practical to implement. Interoperability with a series of design and documentation platforms makes ETABS a coordinated and productive tool for designs which range from simple 2D frames to elaborate modern high-rises.
