The availability of easily accessible databases of earthquake records allows the use of large sets of accelerograms for dynamic analyses of geotechnical systems.

Abstract

The availability of easily accessible databases of earthquake records allows the use of large sets of accelerograms for dynamic analyses of geotechnical systems. However, the selection of acceleration records is influenced by multiple sources of uncertainty related also to the geotechnical properties of the soil deposit which strongly affect the site seismic response. The authors recently proposed a procedure for a proper selection of the input ground motion to be used in 1D seismic site response analyses. An application of the procedure is presented and discussed in the paper highlighting the relevant influence of soil heterogeneity on the results of the accelerograms selection procedure.
