A Building Classification System for Multi-hazard Risk Assessment

Abstract A uniform and comprehensive classification system, often referred to as taxonomy, is fundamental for the characterization of building portfolios natural hazard risk assessment. taxonomy characterizes assets according attributes that can influence likelihood damage due effects hazards. Within scope Global Earthquake Model (GEM) initiative, a (GEM Building Taxonomy V2.0) was developed with goal classifying buildings their seismic vulnerability. This contained 13 attributes, including main material construction, lateral load-resisting date construction number stories. Since its release in 2012, has been used by hundreds experts working on exposure modeling efforts. These applications allowed identification several limitations, which led improvement expansion this into new system compatible multi-hazard expanded (named GED4ALL) includes more details relevant exposed hazards beyond earthquakes. GED4ALL applied international initiatives, enabling most common classes world, facilitating compatibility between models databases vulnerability databases.
