4. Conclusions This paper describes the built up of a database of the school buildings of the Marche region, realized by merging three sources of information related to geometry features, structural typologies, post-earthquake surveys and level of PGA experienced during the 2016 Central Italy seismic sequence. A probabilistic model that returns damage starting from an earthquake intensity measure has been proposed. The applicability of the model, once identified suitable shape functions, has been studied by finding the parameters of the model through the MLE method, starting from the data relating to the central Italy 2016 earthquake. Acknowledgements The research was carried out within the activities of the Italian National ReLUIS Project 2019-2020 “MAppe di Rischio e Scenari di danno sismico (MARS) - Task 4.7 – Modelli e curve di fragilità per le scuole e altri edifici strategici o rilevanti”. The Authors are grateful to the Reconstruction Office of the Marche Region for having provided data related to post-earthquake surveys to damaged schools.
