| Abstract | It is known that cyclic shear stresses induced by earthquake, cause a range of shear strain due to granular and index properties of soil and thus losing shear strength of soil and changing stress-strain behavior. In particular, saturated loose sands differ from the other type of soils because of losing quickly their shear strength due to strain softening under cyclic loading. In this study, changing in stress-strain properties of saturated sand having different physical characteristics under different test conditions was investigated with a series of hollow cylindrical torsional shear test in laboratory. In the tests, which are performed on sand using torsional shear apparatus, the changes of the shear stress amplitude, the excess pore water pressure and the shear strain due to the number of cycles shall be determined. The effect of some factors on stress- strain relationships in sand was evaluated with stress-controlled, consolidated-undrained tests. The changes of the shear modulus and the damping ratios depends on the shear strain amplitude were tried to determine in different confining stresses, relative densities and initial consolidation conditions with performed tests. In results of the tests, it was seen that the stress-strain behavior of sand was significantly influenced by these factors. |
