BUILDING BACK BETTER: THE CASE STUDY OF THE FAZZINI COLLEGE

Passive protection systems have proven to be efficient solutions for the seismic protection of both new and existing buildings. Recently an increasing attention is paid towards their use in external configurations, especially for existing structures since their lower interferences with both the structures to protect and the activities carried on within the buildings. Retrofit and seismic upgrading based on external dissipative elements, indeed, are very promising in postearthquake phases, making it possible a notable reduction of building downtime and impacts on users. This paper concerns the seismic retrofit of the Fazzini college, an existing r.c. frame building of the University of Camerino severely damaged during the 2016 Central Italy seismic sequence. The retrofit has been designed with an external passive system equipped with fluid viscous dampers aiming to prevent damage to both structural and non-structural components up to severe earthquakes.
