FRIBAS database for better characterization of RC and URM buildings: Towards specific T-H relationships

Abstract FRIBAS database is an open access database (https://doi.org/10.5281/zenodo.6505442) made up of the characteristics of 313 buildings (71 masonry, 238 reinforced concrete and 4 mixed types). It collects and harmonizes data from different surveys performed on buildings in the Basilicata and Friuli Venezia Giulia regions (Southern and North-eastern Italy, respectively). Each building is defined by 37 parameters related to the building and foundation soil characteristics. Building and soil fundamental periods were estimated experimentally based on ambient noise measurements. FRIBAS gave us the opportunity to study the influence of the main characteristics of buildings to their structural response and soil-building interaction effect. In this study, we have used FRIBAS dataset to investigate how the building period varies as a function of building typologies and soil conditions. Our results motivate the need of going beyond a ‘one-fits-all’ numerical period-height (T-H) relationship for generic building typologies provided by seismic code, towards a specific characterization of T-H relationships that account for both soil and building typologies.
