Damage and Loss Model Library

Welcome to the Damage and Loss Model Library (DLML), a curated, open-source repository of standardized model parameters and metadata for quantifying the impact of natural hazard events on the built environment.

This library is a project from the NHERI SimCenter designed to address a critical gap in natural hazards engineering: the lack of a centralized, standardized, and easy-to-use repository for damage and loss models. The DLML provides the essential data—model parameters, descriptive metadata, and configuration files—that power natural hazard risk assessment simulations.

Key Features:

  • Standardized Data Schema: A robust yet flexible schema for organizing models by hazard, asset type, and resolution

  • Rich Metadata & Clear Citations: Every model is paired with detailed metadata and clear citations to original sources

  • Broad & Inclusive Collection: Growing collection from industry standards like FEMA P-58 and FEMA Hazus to peer-reviewed research models

  • Automated Documentation: User-friendly documentation with model descriptions, parameter tables, and fragility/consequence function plots

Model Coverage:

The library includes comprehensive model collections for seismic, hurricane, and flood hazards, covering buildings, infrastructure networks, and individual components from sources including FEMA P-58, FEMA Hazus, and peer-reviewed academic research.
