INTEGRATED APPROACH TO EVALUATE THE SEISMIC BEHAVIOR OF A FORMER CHURCH CONVERTED TO A MUSEUM: MARINO MARINI MUSEUM IN FLORENCE

This study explores the seismic behavior of the Marino Marini Museum in Florence (Italy) through an integrated approach. The research aims at realizing a finite element (FE) model that benefits from different sources of information, including advanced three-dimensional surveying techniques, historical documentation and thermography campaign. The Museum is located in the former San Pancrazio Church, a medieval building erected in the 10th century in the center of Florence, inside the UNESCO World Heritage area. Over the centuries, the structure has undergone many transformations, serving as an arcade during the Napoleonic period, a tobacco factory, and finally a museum in 1982. These modifications included the addition of new inner levels and other interventions in steel and reinforced concrete. The current museum is a complex architectural system, constituting the head building of an irregular aggregate made of different masonry units. To realize the FE model, a detailed laser scanner survey has been carried out and the geometrical information has been combined with the historical documentation on the past interventions. Various FE models have been realized to gain insights into the influence of past interventions on the structural behavior of the building, providing useful information for the seismic analysis. Nonlinear dynamic analyses were carried out to provide first insights on the dynamic response of the museum.
