Predicting the small strain shear modulus of coarse-grained soils

Soil Dynamics and Earthquake Engineering, 2021
Abstract Coarse-grained soils are important geotechnical materials widely used in construction. The contribution of particle size distribution on the small strain shear modulus Gmax of coarse-grained soils has not yet been fully recognized. This paper presents an experimental investigation into the effects of the uniformity coefficient Cu and the ...

Reduction of Shear Modulus at Small Strains in Simple Shear

Journal of Geotechnical and Geoenvironmental Engineering, 1997
Cyclic tests were conducted to study the secant shear modulus, Gs, of two reconstituted sands and three laboratory-made clays at small cyclic shear-strain amplitudes γc≈ 0.0006%–0.02%. A recently developed direct simple shear device for small-strain testing was employed. The effects of cyclic strain amplitude (γc), type of soil and plasticity index (PI)

Small-Strain Shear Modulus of Cement-Admixed Kaolinite

Geotechnical and Geological Engineering, 2011
An experimental study is conducted to measure small-strain shear modulus of clay-cement mixture using bender element apparatus setup in a triaxial cell. Bender element tests were conducted on cement-treated soils and the results were analyzed to study the variation of shear modulus properties of soil specimens at different cement contents, confining ...

Laboratory Measurement of Small-Strain Shear Modulus of Volcanic Soil

Geo-Congress 2014 Technical Papers, 2014
Volcanic soils can be found in many places around the world. In comparison to conventional soils, their mechanical behavior is less extensively studied in the laboratory. In this study, a series of laboratory tests has been carried out to investigate the small-strain shear modulus ( G 0 ) of a volcanic soil sampled from northeastern Japan, using the ...

Unified Model for Small-Strain Shear Modulus of Variably Saturated Soil [PDF]

Journal of Geotechnical and Geoenvironmental Engineering - ASCE, 2016
AbstractThe small-strain shear modulus G0 is a property fundamental to the deformation response of soils to dynamic loading. It depends on soil mineralogy, particle characteristics, void ratio, effective stress, and the degree of saturation. Some theories have been established to predict G0 of soils under variably saturated conditions.

Mechanisms of Small-Strain Shear-Modulus Anisotropy in Soils

Journal of Geotechnical and Geoenvironmental Engineering, 2008
In this paper, experimental studies using a true triaxial apparatus and a bender element system, and numerical simulations based on the discrete element method (DEM) were used to investigate the stress- and fabric-induced shear-stiffness anisotropy in soils at small strains. Verified by experiments and DEM simulations, the shear modulus was found to be

Small strain shear modulus of anisotropically loaded sands

Soil Dynamics and Earthquake Engineering, 2019
Abstract This study aims to investigate the significant influence of stress anisotropy and different stress components on the small-strain shear modulus of sands using a comprehensive set of bender element tests on sand specimens undergoing anisotropic stress state along variable stress paths. Particular attention is given to the contribution of sand
