ETABS 23.3.0 Enhancements - Date: 2-Jul-2026



Key Features:

• Integrated modeling environment for multi-story building structures
  
• Grid-based workflow tailored for structural engineering projects
  
• Supports static, dynamic, and advanced nonlinear analysis methods
  
• Code-based design checks for reinforced concrete and steel systems
  
• Wind load automation with regional code compliance options
  
• Seismic analysis using modal and response spectrum methods
  
• Nonlinear modeling with plastic hinges and fiber elements
  
• Advanced result extraction tools including story-level force reporting
  
• Database export options including SQLite format support
  
• API access for automation and custom engineering workflows
  

Design
Concrete and post-tensioned slab design has been updated to support CSA A23.3:2024 provisions, improving compatibility with current Canadian structural design standards.


Loading
Wind load generation has been enhanced with support for KDS 41 12 00:2022, including automated gust factor calculation and optional cross-wind and torsional effects depending on structural configuration.


Structural Model
A new Story Inertial Forces output table has been introduced, allowing direct extraction of floor-level inertial forces for modal and response spectrum cases without relying on manual section-cut workflows.


Application Programming Interface (API)
The API now supports .NET 10 clients via COM integration, extending compatibility with modern development environments and automation pipelines.


Output and Display
Section Cut processing has been refined for auto-meshed area objects. When all defining joints are included, internal elements and generated joints are now automatically accounted for in force calculations.

What's New:

• Added concrete and PT slab design support for CSA A23.3:2024
  
• Introduced automated wind loading per KDS 41 12 00:2022
  
• Added gust factor calculation for rigid and flexible structures
  
• Optional cross-wind and torsional effects in wind analysis
  
• New Story Inertial Forces output table for floor-level results
  
• SQLite export support for database tables
  
• .NET 10 compatibility via COM-based API access
  
• Improved performance in element model generation loading calculations
  
• Updated section-cut behavior for auto-meshed area objects
  
• Alphabetical sorting of load cases and combinations throughout the interface
