Predictive Model for Normalized Shear Modulus of Cohesive Soils
called maximum shear modulus, Gmax. It can be determined by in-situ methods from the measurements of the shear wave velocity, Vs, by means of crosshole, down-hole, up-hole, or surface wave testing. The relationship between maximum shear modulus and shear wave velocity is rigorous: 2 max s G V where ρ is soil density. This parameter can be also obtained in laboratory by resonant column or ...
متن کاملShear Modulus of Soils under Cyclic Loading at Small and Medium Strain Level
The main purpose of this paper is to investigate the stiffness of soils under cyclic loading at small and medium strain level. The influence of some important factors on the shear modulus of soils such as: the strain level, the plasticity index and the mean effective stress are discussed in detail. Behaviour of different kind of soils is also compared based on available laboratory data includin...
متن کاملEffects of Degree of Consolidation and Anisotropic Consolidation Stresses on Shear Modulus and Damping Ratio of Cohesive Soils at Low Strain
During consolidation process of saturated cohesive soil the soil stiffness increases. Increase of the effective stress due to dissipation of excess pore pressure causes additional stiffness of soil mass. This phenomenon has a very important effect on the behavior of saturated cohesive soils during dynamic loading. In the current investigation the changes in maximum shear modulus. Gmax and dampi...
متن کاملInterpreting measurements of small strain elastic shear modulus under unsaturated conditions
Bender element testing of unsaturated isotropically compacted speswhite kaolin samples was used to investigate the variation of small strain elastic shear modulus G under unsaturated conditions. Testing was performed in a suction-controlled triaxial cell and involved combinations of isotropic loading and unloading stages and wetting and drying stages. Analysis of the experimental results indica...
متن کاملPure shear axes and elastic strain energy
It is well known that a state of pure shear has distinct sets of basis vectors or coordinate systems: the principal axes, in which the stress σ is diagonal, and pure shear bases, in which diagσ = 0. The latter is commonly taken as the definition of pure shear, although a state of pure shear is more generally defined by trσ = 0. New results are presented that characterize all possible pure shear...
