CSI ETABS v22.3.0 (2024)

The innovative and revolutionary new ETABS is the ultimate integrated software package for the structural analysis and design of buildings. Incorporating 40 years of continuous research and development, this latest ETABS offers unmatched 3D object based modeling and visualization tools, blazingly fast linear and nonlinear analytical power, sophisticated and comprehensive design capabilities for a wide-range of materials, and insightful graphic displays, reports, and schematic drawings that allow users to quickly and easily decipher and understand analysis and design results.

From the start of design conception through the production of schematic drawings, ETABS integrates every aspect of the engineering design process. Creation of models has never been easier – intuitive drawing commands allow for the rapid generation of floor and elevation framing. CAD drawings can be converted directly into ETABS models or used as templates onto which ETABS objects may be overlaid. The state-of-the-art SAPFire 64-bit solver allows extremely large and complex models to be rapidly analyzed, and supports nonlinear modeling techniques such as construction sequencing and time effects (e.g., creep and shrinkage). Design of steel and concrete frames (with automated optimization), composite beams, composite columns, steel joists, and concrete and masonry shear walls is included, as is the capacity check for steel connections and base plates. Models may be realistically rendered, and all results can be shown directly on the structure. Comprehensive and customizable reports are available for all analysis and design output, and schematic construction drawings of framing plans, schedules, details, and cross-sections may be generated for concrete and steel structures.

ETABS provides an unequaled suite of tools for structural engineers designing buildings, whether they are working on one-story industrial structures or the tallest commercial high-rises. Immensely capable, yet easy-to-use, has been the hallmark of ETABS since its introduction decades ago, and this latest release continues that tradition by providing engineers with the technologically-advanced, yet intuitive, software they require to be their most productive.

Some new features in Etabs v22.3.0

• Added evaluation of serviceability of steel frame floor systems subject to walking vibrations in accordance with AISC Design Guide 11, Chapter 7.
• An enhancement was made to add the ability to automatically generate non-linear frame hinges per ASCE 41-23 recommendations
• Conversion of curved concrete beams to facing slabs available. Until now only straight beams could be converted.
• Added response spectrum function for Kyrgyztan “SNiP KR 20-02:2018”.
• Added automatic wind loading for Vietnamese code TCVN 2737:2023.
• Added AISC 360-22 design code for design of steel structures (including AISC 341-22 Seismic Provisions), design of composite beams, design of composite columns, and design of steel connections.
• Added composite column design per CSA S16-19 design code.
• The steel beam design has been improved with the following new features: Added the new beam design code SJI 100-2020. A new steel beam section type, “Custom Beam Section,” has been added, the definition of which includes component section data. A detailed calculation report has been implemented.
• An improvement was made to add joint cutting design for ACI 318-19 concrete frame design. Joint cutting is now performed for: Ordinary Moment Frames (OMF) in Seismic Design Category (SDC) B, using the nominal flexural strength of the beams. Intermediate moment frames (IMF), using the nominal bending resistance of the beams. Special moment frame (SMF), using the probable bending resistance of the beams.
• An improvement has been added for special structural concrete shear walls per ACI 318-19. The design is now carried out using the amplified factored shear force, Ve = Omega_v * w_v * Vu < 3.0 * Vu) according to section 18.10.3.1. This Special Structural Walls check was not present in previous versions.
• An improvement was made to the ACI 318-19 concrete frame design code so that it now considers the interaction of shear forces in the major and minor directions in a column per sections 22.5.1.10 and 22.5.1.11.
• An improvement has been made to speed up beam design by using parallel processing.
• The design of steel beams according to the 2010 SJI code has been improved so that design calculations can now be exported to reports and tables.
• A new materials library has been added for US materials based on ASTM A1085/1085M specifications.
• New frame section libraries have been added conforming to AISC Shapes Database v16.0.
• Automatic wind load calculations for AS/NZS 1170.2:2011 and 2021 load codes have been added to the project report.
• The ETABS v22 API has been updated to support .NET 8.
