CHURCH OF SANTA MARIA DI PAGANICA
This article investigates the vulnerabilities that might have caused the collapse of Santa Maria di Paganica’s Church during April 6, 2009 earthquake and following shocks, at the same time trying to establish their possible mechanisms. The main elements of such vulnerability have been identified in the quality of the masonry walls (type and size of inert and type of binding materials), in the lack of an effective anchor between the different elements of the building (made by inserting wood elements into the 1700 built walls), in the interaction between the church and the rigid donjon (built close to it) as well as in the type of the nave roofing (without any anchor and therefore really vulnerable to horizontal actions). Finally there is a hypothesis, based on current knowhow, concerning the possible sequence of the collapses of the different portions of the church, at the same time identifying, for each kinetic mechanism , the possible causes of primer and its evolution.
