A Review of the Effect of Different Parameters on the Dynamic Properties of the Soils

Shear modulus and damping ratio are the most important material properties that determine the behavior of soils under dynamic loadings. Basically, when a soil is subjected to earthquake or cyclic loading, the shear modulus and damping ratio of the soil are influenced by many factors. These factors are divided into two categories: factors related to soil specification and load characteristics entered into the soil. This paper presents a review on the dynamic soil properties and their influencing parameters. Earlier studies on dynamic soil properties are presented systematically to highlight the importance of the each influencing parameter.
