Preface

This volume collects the papers submitted to the 8th Civil Structural Health Moni- toring Workshop, which was held online on March 29-31, 2021. The workshop was jointly organized by the University of Molise, the University of Naples "Parthenope," S2X s.r.l., and the ISHMII Association. The workshop is part of an international conference series with a long tradition. Previous editions of the workshop were organized since 2004 in the USA, Italy, Canada, Germany, Japan, Northern Ireland, and Colombia. This edition was origi- nally intended to be organized in Naples (Southern Italy), but it turned into a full online event in agreement with the social distancing norms due to the COVID-19 pandemic. The main theme of the workshop was "Ageing structures and infrastructures in hazardous environment"; this is currently a very hot topic worldwide and particularly in Italy, after the collapses of several bridges and, above all, of the Morandi's Bridge in Genoa.
