Analysis of the Battistero di San Giovanni’s behavior subjected to seismic events

Resumo

The analysis behavior of historical structures over the years constitute a fundamental research’s field to
perpetuate the constructive methods and the cultural heritage of civilizations. Such analyzes involve not only the
static aspect but also the seismic action, present in a large part of the world territory and which subjects several
structures to vibrations. Evaluating the historic masonry construction’s vulnerability against earthquakes, many
studies are carried out to guarantee the protection of structures and consequently the cultural heritage. With the
ease of access to computational means, a large part of the historic building’s studies has been carried out using the
finite element method, with the aid of computational tools made available by commercial software. In this context,
the Italian municipality of Florence, which has the highest concentration of universally renowned works of art, is
in a seismic zone, presenting episodes of earthquakes in the month of June 2023, with 4.0 Mw of magnitude. Thus,
the present work aims to numerically analyze the dynamic behavior of the Battistero di San Giovanni, from the
4th-5th centuries, located in Florence. Its behavior against seismic events is evaluated from the structural analysis
by the finite element method, using the ABAQUS software.
