FEM-based buckling analysis of steel sections is now available via the integrated BucklingFEM plugin, enabling detailed eigenvalue buckling analysis of steel frame elements, capturing both global and local buckling modes. Shear wall design, concrete frame design, and reinforced concrete and PT slab design per ACI 318-25 are now supported. Additional new codes include shear wall design per CSA A23.3-24 and CSA A23.3-19, concrete shell design per Eurocode 2-2004, and concrete frame design per TCVN 5574:2018.

ETABS 23.1.1 Enhancements - Date: 8-Dec-2025

Data Exchange

Importing a SAFE model into ETABS is now supported at a user-selected story level, with advanced options for merging geometry, property definitions, and load assignments.



Analysis

FEM-based buckling analysis of steel sections is now available through the integrated BucklingFEM plugin. Steel frame elements can be converted into detailed FEM models for eigenvalue buckling analysis. This enables the capture of both global and local buckling modes, providing a more realistic assessment of member stability than traditional simplified checks. This feature is limited to the Ultimate level license.



Design

Shear wall design, concrete frame design and reinforced concrete and PT slab design for ACI 318-25 are now all available.



Shear wall design according to CSA A23.3-24 and CSA A23.3-19 is now available.



Concrete shell design according to Eurocode 2-2004 is now available.



Concrete frame design according to the Vietnamese TCVN 5574:2018 code is now available.





ETABSis 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.
