Shear Modulus Degradation of Liquefying Sand: Quantification and Modeling
… greatest challenges. The ability to quantify the degradation of a soil's shear modulus as it undergoes liquefaction would help engineers design more reliably and economically. This thesis uses ground motions recorded by an array of downhole accelerometers on Port Island, Japan, during the 1995 …

Influence of some particle characteristics on the small strain response of granular materials
… of geomaterials are the very small strain shear modulus, Gmax, shear modulus degradation G/Gmax, and damping ratio. These are also important parameters in the design of foundations where only small deformation takes place. A review of the literature suggests that shear modulus and damping …

The effects of multi-directional loading on soil liquefaction
… first time, the influence of multi-directional shearing on soil behaviour, especially the undrained behaviour of saturated sands, remains one of the least understood areas in geotechnics. This study developed a new test database on Hostun sand with the modified multi-directional simple shear …

Frequency- and pressure-dependent dynamic soil properties for seismic analysis of deep sites
… the applicability of commonly used standardized shear modulus degradation and damping curves versus shear strain amplitude. The most widely employed degradation and damping curves, are those originally proposed by Seed & Idriss, 1969. Laboratory experimental data (Laird & Stokoe, 1993) performed …
