Numerical and experimental analysis of the leaning Tower of Pisa under earthquake

چکیده مقاله :
Twenty years have passed from the most recent studies about the dynamic behavior of the leaning Tower of Pisa. Significant
changes have occurred in the meantime, the most important ones concerning the soil-structure interaction. From 1999 to 2001,
the foundation of the monument was consolidated through under-excavation, and the "Catino" at the basement was rigidly
connected to the foundation. Moreover, in light of the recent advances in the field of earthquake engineering, past studies about
the Tower must be revised. Therefore, the present research aims at providing new data and results about the structural response of
the Tower under earthquake. As regards the experimental assessment of the Tower, the dynamic response of the structure
recorded during some earthquakes has been analyzed in the time- and frequency-domain. An Array 2D test has been performed
in the Square of Miracles to identify a soil profile suitable for site response analyses, thus allowing the definition of the free-field
seismic inputs at the base of the Tower. On the other hand, a synthetic evaluation of the seismic input in terms of response
spectra has been done by means of a hybrid approach that combines Probabilistic and Deterministic Seismic Hazard Assessment
methods. Furthermore, natural accelerograms have been selected and scaled properly. A finite element model that takes into
