Software Platform for the Assessment of Seismic Risk in Romania Based on the Use of GIS Technologies

Abstract eng:
The structure of the ROSERIS software platform consists of a core GIS application and of two “satellite” applications dedicated to building stock data collection and management and to seismic risk analysis. Data is stored in a geodatabase containing building stock data, geospatial references and seismic hazard information. Building stock is classified according to a building typology matrix, assembled based on structure type, structure height and seismic design code level. Seismic hazard is defined by a simplified approach, compatible with the new Romanian seismic design code, entirely harmonized with Eurocode 8. The risk assessment methodology built in the platform uses fragility curves for different structure typologies in Romania, derived from previous studies carried out by some of the university members of the team. Typical output values consist of probabilities corresponding to damage states, as well as of mean damage ratios. Both input and output data are mapped or presented by means of several types of reports, by using the graphical user interface of the core GIS application.
