RETROFITTING OF SACRAL BUILDINGS AFTER THE RECENT EARTHQUAKES IN CROATIA

Abstract

After the Petrinja earthquake in December 2020, 442 individual immovable cultural assets were damaged, including 124 cultural heritage buildings that suffered severe structural damage. The largest number of damaged cultural heritage assets concern sacral buildings, mainly churches and chapels. In this paper, a brief overview of the damage to several sacral buildings after the earthquakes in Croatia is presented. The failure mechanism and typical damages are presented graphically. In addition, special emphasis is placed on the complete retrofitting of a damaged church. The condition assessment, numerical modelling and full seismic retrofit of the selected church is shown.
