Computers and Structures, Inc. (CSI), is pleased to announce the availability of ETABS 22.x. This release adds the AISC 360-22/AISC 341-22 steel frame, composite beam, composite column, and connection design. CSA S16-2019 composite column design has also been added, as well as updates for the latest SJI-2020 joist design. For those working with steel-framed floor systems, serviceability assessment of these floors subjected to walking vibrations has been added following Chapter 7 of the AISC Steel Design Guide 11. ETABS now includes automatic generation of nonlinear hinges per ASCE 41-23 (Ch 9 for steel, and Ch 10 for concrete). In addition, the ETABS API now supports .NET 8.

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.
