abstract = {<div data-language="eng" data-ev-field="abstract">This study investigated a new predictive model of the shear modulus reduction (G/G<inf>max</inf> - Log (γ<inf>c</inf>)) and damping ratio (Ξ - Log (γ <inf>c</inf>)) curves for sensitive eastern Canada clays. The model was established based on experimental measurements of G/G<inf>max</inf> and Ξ performed on 69 sensitive clay specimens from eastern Canada. The compiled database was first analyzed to qualitatively assess the influences of different soil parameters on the measurements. Next, statistical analyses using regression analysis and the modified hyperbolic model were performed. It was found that the G/Gmax and Ξ values of sensitive eastern Canada clays were influenced mainly by the plasticity index (I<inf>p</inf>), mean effective stress (σ′<inf>m</inf>), and structure, which was quantified by the liquidity index (I<inf>L</inf>). Based on the statistical analysis performed, new equations for G/G<inf>max</inf> and Ξ were proposed. The newly proposed model was compared with previously published models. The comparison clearly showed that the proposed model was more representative of sensitive eastern Canada clays. Consequently, it is suggested that the proposed model is more appropriate for use in the dynamic analysis of sensitive eastern Canada clay deposits as well as other similar soils.<br/></div> © 2023, Canadian Science Publishing.
