Checking the site categorization criteria and amplification factors of the 2021 draft of Eurocode 8 Part 1–1
Roberto Paolucci,Mauro Aimar,Andrea Ciancimino,Marco Dotti,Sebastiano Foti,Giovanni Lanzano,Pietro Mattevi,Francesca Pacor,Manuela Vanini +8 more
TL;DR: In this article, the site categorization criteria and corresponding site amplification factors proposed in the 2021 draft of Part 1 of Eurocode 8 (2021-draft, CEN/TC250/SC8 Working Draft N1017) are first introduced and compared with the current version of Euro code 8, as well as with site amplification factor from recent empirical ground motion prediction equations.

On seismic response of stiff and flexible retaining structures
Nathaniel Wagner,Nicholas Sitar +1 more
TL;DR: In this paper, the authors present an overview of the results of experimental and analytical studies of the seismic response of stiff and flexible retaining structures and show that the Mononobe-Okabe (M-O) method of analysis provides a reasonable upper bound for the response of retaining structures.

κ0 for soil sites: Observations from KiK-net sites and their use in constraining small-strain damping profiles for site response analysis:
Boqin Xu,Ellen M. Rathje,Youssef M. A. Hashash,Jonathan P. Stewart,Kenneth W. Campbell,Walter J. Silva +5 more
TL;DR: In this paper, small-strain damping profiles developed from geotechnical laboratory testing have been observed to be smaller than the damping inferred from the observed site amplification from downhole array reco...
An Improved Description of the Seismic Response of Sites with High Plasticity Soils, Organic Clays, and Deep Soft Soil Deposits
TL;DR: Carlton et al. as mentioned in this paper developed a simplified procedure to estimate design spectra for non-liquefiable NEHRP F sites, specifically sites with organic soils, highly plastic soils, and deep soft soil deposits.

Simple shear testing of sensitive, very soft offshore clay for wide strain range
Giuseppe Lanzo,Giuseppe Lanzo,Alessandro Pagliaroli,Alessandro Pagliaroli,P. Tommasi,P. Tommasi,Francesco Latino Chiocci,Francesco Latino Chiocci +7 more
TL;DR: In this article, the stiffness and damping properties of very soft clay sediments of the Italian Adriatic continental shelf were determined by means of two series of cyclic simple shear tests.

Moduli and Damping Factors for Dynamic Analyses of Cohesionless Soils
TL;DR: In this article, a simple relationship is proposed to relate the shear modulus of a cohesionless soil to a modulus stiffness coefficient, which is a soil property and depends on the characteristics of the soil, and the effective mean principal stress at any point in the soil.
