Abstract

ABSTRACT: Traditional vulnerability methodologies rely on collecting building data through time consuming surveys and visual screening. Geospatial infrastructure systems have rapidly evolved and today we can access massive geospatial data. Digital cadastral databases combine location, attributes, and temporal information for building stock. This paper proposes a GIS-based framework to estimate seismic vulnerability and losses from cadastral data only. The framework is rooted on well-known displacement-based procedures and uses probabilistic models of the building structural capacity. A featured application to 287, 503 housing units in metropolitan area of Granada is presented to showcase outputs for decision-making: performance displacement, damage level and repair cost.
