New Gene Expression Programming models for normalized shear modulus and damping ratio of sands
TL;DR: This paper proposes several new models based on GEP for dynamic properties of sands that can predict normalized shear modulus and damping ratio of sands and demonstrates that the proposed models are capable of estimating the dynamic parameters of sands more accurately.
Journal ArticleDOI
Dynamic modulus characteristics of saturated clays under variable confining pressure
TL;DR: In this paper, a series of cyclic triaxial test cases were used to investigate the cyclic variation of both shear stress and normal stress components on the soil elements.
Journal ArticleDOI
Effect of coupling excess pore pressure and deformation on nonlinear seismic soil response
TL;DR: In this article, a Biot hydraulic and mechanical computation of a saturated soil deposit with coupling pore pressures and soil deformations was performed with a fully nonlinear elastoplastic multi-mechanism model.
Journal ArticleDOI
Scaling Shear Modulus from Small to Finite Strain for Unsaturated Soils
TL;DR: The stress-dependent curve of shear modulus degradation with increasing shear strain amplitude is a fundamental mechanical property of soils as discussed by the authors, and it is well known that the degree of stress dependent degradation is a sign of soil fertility.
Journal ArticleDOI
Challenges associated with site response analyses for soft soils subjected to high-intensity input ground motions
TL;DR: In this paper, the authors used equivalent linear and nonlinear 1D site response analyses for the well-known Treasure Island site to demonstrate challenges associated with accurately modeling large shear strains, and subsequent surface response, at soft soil sites.

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.
