| dc.description.abstract | The nature and distribution of earthquake damage is strongly influenced by the response of soils to cyclic loading, and the behavior of soils subjected to dynamic loading is influenced by dynamic soil properties. The determination of these dynamic soil properties is invaluable in the response analysis of soils to cyclic loading. Of these dynamic soil properties, shear modulus and damping ratio are the most important; and this paper is concerned with the determination of the shear modulus and damping ratio of sand. In this research the shear modulus and damping ratio of Koka sand is determined using the cyclic simple shear test. The results have shown that the obtained normalized shear modulus values are located lower than those suggested in literature, especially at lower strains. For higher strains the obtained normalized shear modulus values agree with those suggested in literature. The obtained damping values are almost within the range suggested in literature. | en_US |
