Seismic prevention and rehabilitation of nonstructural elements. Application experiences of nonstructural pre-seismic evaluation

Topics concerning nonstructural seismic prevention and rehabilitation take their place in the main context of buildings safety in order to explore some aspects of performance of those technical elements. They have become very topical in Italy in the last decade since the repetition of seismic events has made vulnerability and its implications obvious not only in terms of safety risk. This paper reports briefly about author research experiences in this topic and more detail an experience as a component of research team, organizer and tutor in the activities of an international cooperation project between University of Palermo and University of California-Berkeley. After a short introduction on the general topics and the state of the art, the paper focuses particularly on experience of preseismic nonstructural evaluation characterizing buildings campus of Palermo transposing the USA experience to case studies under review.
