To understand the strain-dependent shear modulus and damping ratio of reconstituted pumice sand samples, a series of dynamic deformation tests was performed using hollow cylindrical torsional shear test apparatus. The effects of confining pressure level and ...

<p>Soil liquefaction is conventionally evaluated through an empirical framework based on accumulated experience from case histories - the "NCEER Method". However, the empirical framework contains inconsistent physics and characterizations that are unrelated ...

<p>The shear modulus, known as Gmax , is a key parameter for predicting the static and dynamic behavior of soils. Its value decreases by increasing the shear strain. This is because of reducing the soil&rsquo;s stiffness as a result of increasing the shear ...

For a practical approach in routine site characterizations, the minimal standard of work should be seismic piezocone tests (SCPTu) or seismic flat dilatometer tests (SDMT), as up to 5 separate measurements of soil behavior are captured during a single sounding. ...

Laboratory and field measurements of the small-strain shear modulus of a Piedmont residual soil were compared to gain a better understanding of mechanisms affecting stiffness. Resonant column tests were performed to study influences of void ratio, overconsolidation ...
