Static and dynamic soil characterization at Roio Piano (AQ)

Following the 6 April 2009 earthquake which hit the Abruzzo region, numerous static and dynamic field soil characterizations have been performed, in order to analyze the seismic response of soils (GRASSO et al. 2005, LANZO et al., 2011, MAUGERI et al., 2011) and recover or retrofit buildings and important historical monuments. Among the numerous on-site investigations which took place in different parts of L'Aquila province, this paper reports the site investigations at Roio Piano. In particular, the results from in situ Seismic Dilatometer Marchetti Tests (SDMT) and soil laboratory tests are reported. As regards dynamic laboratory tests, the resonant column test was used to evaluate the soil geotechnical parameters in terms of the shear modulus G-γ and damping ratio D-γ
