CSI ETABS 22.5.1 (3923)

Computers and Structures, Inc. (CSI) has released ETABS 22.5.1 (3923). ETABS 22.5.0 and 22.5.1 include improvements for the definition of nonlinear area springs. CSA S16:2024 has been added for design of steel frames, composite beams, and composite columns. Seismic loading according to AS 1170.4-2024 is now available. Improvements have also been made to the user interface to better handle the location of forms when using multiple monitors.

ETABS 22.5.0 Enhancements - Date: 18-Feb-2025


Structural Model
An enhancement has been implemented to allow the definition of Elasto-Plastic nonlinear behavior for the area spring property without the need to define a link property to specify this behavior


Steel Design
Steel frame design according to CSA S16:2024 is now available.
Composite Beam Design
- Composite beam design according to CSA S16:2024 is now available.
- Composite column design according to CSA S16:2024 is now available.


Loading
Auto seismic loading and response spectrum function according to AS 1170.4-2024 has been added.


An enhancement was made to the NBCC 2020 response spectrum function to add smaller time-steps for computing the intermediate acceleration based on Log-Log Interpolation as specified in Section A.4.1.8.4.(6) of the NBCC 2020 code.
User Interface
An enhancement was made to position forms with respect to the main application window for single and multiple screens. Floating windows are loaded at their previous location on any screen.

ETABS 22.5.1 Enhancements - Date: 25-Feb-2025

1253 An incident was resolved where compression only or tension only area springs were not working correctly in nonlinear analysis. This was a bug inadvertently introduced in v22.5.0 only. Models run in v22.5.0 need to be reanalyzed in v22.5.1 or later.
11246 An incident was resolved in the NBCC 2020 auto seismic load pattern where editing the load pattern via interactive database would revert all load pattern parameters to NBCC2015 with default values.


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.
