In the field of Earthquake Engineering & Engineering Seismology, Studio Geotecnico Italiano enjoys international reputation for carrying out seismic hazard analyses (SHA) allowing one to determine the Design Earthquake ground motions for important infrastructure, such as long bridges, expressway viaducts, LNG terminals, and harbor facilities. Such analyses encompass the assessment of the seismotectonic context in the site region, the post-processing of the earthquake catalogues, the selection of ground motion attenuation models, the construction of a logic tree for handling uncertainties, the computation (probabilistic or deterministic) of site-specific elastic response spectra and the selection of appropriate acceleration time histories to represent the expected ground motion. For important industrial plants, extending over large areas, the SHA can take the form of seismic microzonation, whereby variations in the seismic ground shaking can be predicted over short distances due to changes in near-surface geology and soil profile characteristics.

In the contiguous field of Geotechnical Earthquake Engineering, Studio Geotecnico Italiano has a vast experience in the stability analyses of foundation soils and geo-strictures, including the assessment of the hazards of seismic liquefaction and ground settlements caused by cyclic earthquake loading. This task can be approached both by standard simplified methods based on field penetration tests and by sophisticated numerical simulation tools using two-phase (soil + water), non-linear finite element analyses. The results of these analyses provide a sound basis for the selection of the best ground remediation measures, such as heavy tamping, vibro-flotation, and the like.

Dynamic soil-foundation interaction is a further specialized area in which Studio Geotecnico Italiano has been active since many years, typically providing to structural and mechanical engineers the parameters for a correct analyses of the impact of vibrating machinery, that is the equivalent interaction parameters to be inserted at the foundation level for accurate dynamic analyses of structures. Internal action effects generated in piles by seismic wave propagation in the soil can also be evaluated.
