2. Performance-Based Design (PBD) Wizard

The Ultimate edition now includes a step-by-step wizard for PBD per ASCE 41-17. Users can pushover analysis to determine plastic hinge formation at Service Level Earthquakes (SLE) and Maximum Considered Earthquakes (MCE) with 40% faster iteration times than v21.

Is It Worth Upgrading from ETABS v21 or v20?

If you are currently using a version older than 22.0, the jump to 22.4.0.3843 is immense. The interface modernization (ribbon toolbar similar to AutoCAD 2024) alone saves hours of menu hunting. Furthermore, the updated modal analysis algorithm handles tension-only bracing far more accurately than legacy versions.

However, if you are on version 22.2.x, the upgrade to 3843 is recommended specifically for the improved cold-formed steel links and the 64-bit stability fix. For standard RC buildings under 10 stories, the changes are subtle but beneficial for future code compliance.
