Experimental characterization and analysis of soil behaviour under earthquake loads. 2nd General Report for TC203.

This General Report is addressed to resume and comment 32 papers mostly dealing with the characterization of natural and reconstituted soils under cyclic and dynamic loads reproducing earthquakes in field and laboratory tests, as well as in physical and numerical models. Predictive models are often assessed on the basis of good quality experimental data and field observations from post-earthquake damage reconnaissance are also accounted for. The papers have been grouped according to the engineering purpose of the relevant study, and highlight that the up-to-date technological innovations in geotechnical testing and analysis can nowadays provide a continuous and tangible improvement to the worldwide effort for seismic risk mitigation.
