The paper focuses on the detailed analysis of the dynamic characterisation of polyurethane
to evaluate the effects of polyurethane injections into soil with the aim of geotechnical …

The analysis of the historical reports and previous research projects allowed us to describe
high-level seismic risk scenarios for the city of Catania, located on the eastern coast of Sicily …

The complex cyclic shear stress path experienced by the soil during an earthquake, which
could also induce liquefaction phenomena, can be approximated in the laboratory only by …

Identification of soil condition at the working face of a tunnel boring machine (TBM) is a key
factor for the efficiency and safety of TBM tunneling. The paper presents the first application …

Based on the seismic history of the city of Catania (Italy), the Etna earthquake of 20 February
1818 (IMCS= VIII–IX, MS= 6.2) has been considered as an earthquake scenario. Despite its …

Eastern Sicily is very rich of historical buildings, but at the same time is one of the most
seismically active areas of Italy. In particular, the city of Augusta was damaged by the …

To evaluate the basic data for a seismic response analysis it is possible to use many direct
methods to obtain the shear wave velocity profile of the soil: Down Hole, Cross Hole, SASW …

According to the frequency and the importance of the seismic effects suffered in past times,
the city of Catania, located on the eastern zone of Sicily, must be considered one of the most …

The paper presents a mathematical model for the deformation of soil under irregular cyclic
loading in the simple-shear conditions. The model includes the possible change in the …

This paper analyses the results of undrained cyclic torsional shear and compression loading
triaxial tests run on undisturbed Noto soil. The cyclic torsional shear test was performed …
