3D NUMERICAL SIMULATIONS OF THE SAN MARINO THIRD TOWER (MONTALE) BASED ON 3D MAPPING

Abstract eng:
San Marino historic centre was included in UNESCO world heritage list in 2008. The site is located in a region characterized by medium seismic hazard levels. Therefore, preventing earthquake damages is an important goal for preserving historical buildings and fundamental in order to sustain tourism, a relevant source for the local incomes. In this regard, the historical center was object of an extended project jointly organized by University of San Marino, University of Siena and the Center of Interdisciplinary Science for Art, Architecture and Archaeology California (CISA 3) at University of California, San Diego. In particular, the three middle-age towers of San Marino can be considered a landmark for the Republic and the world. In this framework, the paper aims at calibrating a 3D numerical finite element (FE) of the third tower, called Montale. This study can be seen as a proposal to assess seismic behaviour of historical towers, as well as an easy-to-use model for engineers and consultants all over the world. The presented outcomes will represent an important basis for risk reduction actions by the San Marino authorities.
