CSI ETABS 22.3.0

Computers and Structures, Inc. (CSI), is pleased to announce the availability of ETABS 22.2(3).0. This update add steady state and power spectral density analysis capabilities, as well the ability to model Sumitomo viscoelastic dampers. Composite beam design according to Indian IS 11384:2022 and Chinese GB50017 codes has been implemented. When displaying frame force/moment diagrams, an option to display them with colored contours is now available. Various usability improvements have also been made.

ETABS 22.3.0 Enhancements - Date:17-Oct-2024
Below lists changes made to ETABS since v22.2.0, released 01-October-2024.

* 10880 An enhancement to composite beam design per Eurocode 4-2004 and IS11384 : 2022 was implemented. Users can now specify in the composite beam design preferences whether shear studs are to be welded through the deck, or threaded through holes in the deck. This choice affects the value of the stud strength for shear studs in filled deck ribs with ribs transverse to the beam being designed. Previous versions of ETABS assumed shear studs were always to be welded through the deck.
* 10903 An enhancement to composite beam design per IS 11384:2022 was implemented. The plastic design capacity of composite beams is now computed with the equations listed in IS 11384 Table 17 for beams that support a solid slab, and with equivalent equations for beams that support a ribbed deck. The plastic design capacity was previously computed using slightly different assumptions regarding the stress distribution in the area of concrete in compression. Differences of up to 3% in resulting plastic capacity have been observed.
* 10899 An incident was resolved where some models with links saved in ETABS v22.2.0 could not be reopened in the same version. This has been fixed and these models can now be opened in v22.3.0.
* 0904 An incident affecting composite beam design per IS 11384:2022 was resolved. The minimum percentage of composite action to be applied to beams was computed per Eurocode 4-2004 instead of IS 11384:2022 and accordingly underestimated for certain combinations of grade of steel and beam span, although it never went below 40%. When this occurred, the bending capacity and effective moment of inertia of the design were still sufficient to ensure its adequacy. Also the percentage of composite action of the designs was displayed in both the interactive design form and the output, with the user having the option to choose a higher percentage in the form.
* 10900 An incident was resolved where spandrels could not be designed in ETABS v22.2.0. This has been fixed in v22.3.0.


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.
