The 22.4.0.3843 minor release focuses on software stability, user experience refinements, and data parity: | Feature | ETABS v21 | ETABS v22
In shear wall design, a crucial enhancement is the implementation of as required by ACI 318-19 . This applies to planar walls (i.e., 2D piers) and is compatible with both uniform and overall reinforcing options. Furthermore, the ACI 318-19 shear wall design logic has been refined to now consider the Seismic Design Category (SDC) when determining whether to conduct a wall shear capacity check, adding an extra layer of seismic resilience to the design process.
The "Ultimate" tier is the highest licensing level offered by CSI. It unlocks unrestricted access to the software’s most advanced features. These include nonlinear performance-based design, complex seismic analysis, and advanced material time-dependent behavior modeling. Core Features of ETABS Ultimate
ETABS calculates required longitudinal and shear reinforcing steel for columns, beams, and shear walls. The concrete design engine generates detailed reinforcing summaries, taking into account ductile detailing requirements for high-seismic zones. Shear Wall Design Enhanced handling of massive models with hundreds of
