Abstract
Recent developments in displacement-based design methodologies have increased the need for reliable displacement design spectra, especially in long periods. The design spectra proposed in Eurocode 8 are assessed, using recent attenuation relationships that predict response spectral ordinates based on European data, as well as five selected European strong motion accelerograms. To identify possible trends in long-period spectral displacements, several high-quality digital recordings from the 1995 Hyogoken-Nanbu (Kobe) earthquake were collected and studied. Based on the differences recognised, possible modifications for the design spectrum to take into account in future revision of Eurocode 8 are proposed.Keywords
