Seismic Analysis of the Dry Masonry Bell Tower of the Church of St. Martin in Ruina – Italy : Master's Thesis

Abstract

U ovom radu provedena je numerička analiza ponašanja suho zidanog zvonika uslijed potresnog djelovanja. Analiza je provedena na zidanoj konstrukciji izgrađenoj u 17. stoljeću koja ima namjenu zvonika, a smještena je u gradu Ruina s južne strane rijeke Po u Italiji. Metoda proračuna korištena u ovom radu temelji se na Kombiniranoj metodi konačno-diskretnih elemenata. Zvonik je modeliran s dvije vrste blokova različitih veličina i dvije vrste podloga, uz usvojena tri različita prigušenja. Kao pobuda korišten je potres koji se dogodio u Crnoj Gori-Petrovac 1979. U okviru rada provedena je inkrementalna dinamička analiza do potpunog sloma konstrukcije.In this paper, a numerical analysis of the behavior of a dry masonry belfry due to exposure to seismic action was performed. The analysis was carried out on a brick structure built in the 17th century, which has the purpose of a bell tower and is located in the city of Ruina on the south side of the Po River in Italy. The calculation method used in this paper is based on the Combined finite-discrete element method. The belfry is modeled with two types of blocks of different sizes and two types of foundations, with three different attenuations adopted. The earthquake that occurred in Montenegro-Petrovac in 1979 was used as a stimulus. As part of the paper, an incremental dynamic analysis was carried out until the complete collapse of the structure
