v2.1

This release focuses on improving code quality and enhancing usability of Hazus assessments. The changes maintain backward compatibility while providing users with more flexibility in input specification and ensuring the codebase adheres to modern Python best practices.

Changed

• Input Validation: Relaxed validation constraints for seismic and flood assessments to improve usability:
  • Allow HeightClass attribute for seismic structural systems (W1, W2, S3, PC1, MH) that don't require it in Hazus methodology
  • Remove PlanArea field from auto-populated seismic configuration as it's no longer needed
  • Allow RES1 occupancy buildings to have more than 3 stories in flood assessments, aligning with FEMA technical manual interpretation
• Code Quality: Comprehensive code formatting and linting improvements using Ruff across the entire codebase:
  • Applied consistent code formatting across 15 Python files
  • Fixed docstring formatting and missing docstring issues
  • Cleaned up import statements and unused code
  • Standardized quote usage and line spacing

Fixed

• Resolved spelling issues in comments

v2.0

This release marks a major milestone for the Damage and Loss Model Library and the beginning of a more frequent and structured release schedule. After more than two years of continuous development, v2.0.0 introduces a significantly improved data schema, a host of new models, and a documentation system for model discovery.

For a comprehensive overview of the library in its current state, please see our completely revamped README.md.

Changed

• BREAKING: The core data schema for models has been updated and rationalized to better support a wider range of hazards and asset types. Older custom tools that relied on the v1.0.0 schema will need to be updated.
  • Renamed loss_repair.csv files to consequence_repair.csv for consistency
  • Updated loss measure units to use ratios instead of percentages for Hazus models
  • Improved data validation and multilinear CDF handling in model generation scripts
• Code Quality: Comprehensive code formatting and linting improvements using Ruff, enhancing maintainability and consistency across the entire codebase.

Added

• Model Library Expansion:
  • Hurricane Models:
    • Added complete building models for Hazus Hurricane v5.1 (both original and coupled versions)
    • Added SimCenter Hurricane Wind Component Library with comprehensive wind pressure components from peer-reviewed research
  • Flood Models:
    • Added complete building models for Hazus Flood v6.1
  • Seismic Infrastructure Models:
    • Added Hazus Seismic Power Network models (v5.1)
    • Added Hazus Seismic Water Network models (v6.1)
    • Added Hazus Seismic Transportation Network models (v5.1)
    • Updated Hazus Seismic Building models to v6.1 (in addition to existing v5.1)
    • Added Hazus Seismic Building Subassembly models (v5.1)
• Documentation System:
  • Added an automated documentation website built with Sphinx that allows for easy discovery and exploration of all models in the library
  • Implemented custom Sphinx extensions for automatic generation of model documentation with fragility and consequence curves
  • Added caching system for efficient documentation builds
• Metadata Enhancements:
  • Added rich metadata, including clear citations, for every model to ensure proper credit and academic integrity
  • Enhanced model descriptions and parameter documentation
• Configuration Files:
  • Added Pelicun configuration files for all model libraries to facilitate integration with the Pelicun damage and loss assessment framework

Fixed

• Multiple bug fixes in Hazus model generation scripts and data processing
• Corrected fragility parameters and damage state definitions across various model libraries
• Fixed issues with multilinear CDF data validation and processing
• Resolved metadata formatting and JSON structure issues
