Computers and Structures, Inc. (CSI), is pleased to announce the availability of ETABS 21.0.0 (3143). This release now integrates all concrete and steel detailing, including drawing production and management, inside the same interface with modeling, analysis, and design. The latest American and Canadian loading codes have been added, as well as new design codes, enhanced output for cracked-slab and nonlinear shear wall performance, and other enhancements.

ETABS 21.0.0 - Released 6-Apr-2023 Detailing
Detailing of concrete and steel structures, as well as the production and management of schematic design drawings, is now available from a new Detailing menu inside ETABS. It can now handle multiple towers as well.

Loads assigned to null lines and null areas applied in any local or global direction are now transferred to the underlying structural floors. In earlier versions only loads in the gravity direction were transferred.

Design
AS 4100:2020 steel frame design has been added.

Database Tables
Performance-check definitions can now be edited when the model is locked and selected for associated tabular output.

Application Programming Interface (API)
Support for .NET 6 has been added including a help topic in the "Key Concepts" folder.

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.
