Shear 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 کاملThe Small Strain Effects to the Shear Strength and Maximum Stiffness of Post-Cyclic Degradation of Hemic Peat Soil
The laboratory tests for measuring the effects of small strain to the shear strength and maximum stiffness development of post-cyclic degradation of hemic peat are reviewed in this paper. A series of laboratory testing has been conducted to fulfil the objective of this research to study the post-cyclic behaviour of peat soil and focuses on the small strain characteristics. For this purpose, a n...
متن کاملThe Validity Assessment of Laboratory Shear Modulus Using In-Situ Seismic Piezocone Test Results
Seismic piezocone device (SCPTu) together with Resonant Column and Cyclic Triaxial test apparatus are employed to measure small strain shear modulus (G0) of carbonate sandy and clayey soils of southern coasts of Iran. A large area of southern regions of Iran is formed from clay, silt and sand. In this study, maximum shear modulus that is derived from both field (by seismic piezocone) and labora...
متن کاملNumerical Discrete Element Simulation Of Soil Direct Shear Test
One of the most common methods to measure soil mechanical properties (namely cohesion and internal friction angle) is direct shear box test. In this paper the development of a three-dimensional (3D) discrete element soil model for simulation of a cohesive soil’s direct shear test is presented. The aim was to calibrate the properties of the Hertz-Mindlin with bonding contact model available in E...
متن کاملSoil-Structure Interaction of Buried Pipes Under Cyclic Loading Conditions
The safety of lifelines, as the most important urban facilities, under different conditions highly depends on the safe design and performance of these buried structures. This cannot be achieved unless their actual behaviors are well understood and considered at the designing stage. A new physical model was developed in Amirkabir University of Technology to study the behavior of buried pipes und...
