Seismic Response Analysis of Monte Po Hill (Catania)

This paper presents the results of a large number of seismic response analyses of the Monte Po hill (Catania, Italy). The interest for this site is because of the presence of several constructions, including a school, in the vicinity of the toe of the slope. In the past, these structures suffered damage related to the precarious stability conditions of the slope and the consequences of some excavation performed during the construction of some buildings in the area. Since all the damaged buildings are still in use, a study of the seismic stability condition of the slope is required. To develop a reliable soil model, available in situ and laboratory test results were analyzed. The seismic response analyses were performed using two records of the December 13, 1990 Santa Lucia Earthquake and artificial acceleration time-histories developed referring to a M-7.0 scenario earthquake. The results show significant differences in the hill response depending on the dynamic characteristics of the involved soils. In particular, considerable effects are related to the variation of the shear modulus and damping ratio with shear strain adopted in soil modeling. The obtained acceleration responses show the possible occurrence of permanent deformations of a potentially unstable soil mass; these phenomena can significantly affect the post-seismic serviceability conditions of some structures involved in the hill.
