Elastic Dynamic Young’s Modulus and Poisson’s Ratio of Sand–Silt Mixtures
Publisher: ASCE
Abstract: The significant influence of silica nonplastic fines content on the small-strain Young’s modulus and Poisson’s ratio of silty sands has been evaluated through a comprehensive set of resonant column tests in the flexural ...
Evolution of Dynamic Properties of Cross-Anisotropic Sand Subjected to Stress Anisotropy
Publisher: ASCE
Abstract: Understanding the evolution of dynamic properties of sand subjected to induced anisotropy is indispensable for an accurate seismic analysis of geostructures. In this study, several bender element and hollow cylinder ...
Nondestructive Shear Stiffness Evaluation of EPS-Sand Composites Using Quartz and Calcareous Aggregates
Publisher: American Society of Civil Engineers
Abstract: The influence of expanded polystyrene (EPS) beads inclusion on the shear stiffness of a quartz-based material and a calcareous-based material has been examined by performing a comprehensive series of non-destructive bender ...
Nonisothermal Failure Envelopes of Strip Shallow Foundations Resting on Partially Saturated Clay Subjected to Combined Inclined and Eccentric Loadings
Publisher: American Society of Civil Engineers
Abstract: Shallow foundations are commonly resting on partially saturated soil and are very likely to be exposed to severe variations of temperature. The degree of saturation and matric suction will be changed at the elevated ...
Effects of Hydrated Lime and Zeolite on the Mechanical Behavior of Calcareous Sand Subjected to Wet–Dry Cycles
Publisher: American Society of Civil Engineers
Abstract: The low bearing capacity and high erosion potential of calcareous soils are major concerns in marine environments. Lime stabilization is one of the earliest and most widely used methods for improving the mechanical properties ...
Effect of Gradation and Particle Shape on Small-Strain Young’s Modulus and Poisson’s Ratio of Sands
Publisher: American Society of Civil Engineers
Abstract: The influence of gradation and particle shape on the small-strain Young’s modulus of dry sands is investigated through a comprehensive set of resonant column tests in the flexural mode of vibration. Experiments are performed ...
Limit Analysis of Modified Pseudodynamic Lateral Earth Pressure in Anisotropic Frictional Medium Using Finite-Element and Second-Order Cone Programming
Publisher: ASCE
Abstract: This paper aims at analyzing the active and passive lateral earth pressures exerted on retaining walls due to the anisotropic medium of dry and noncohesive backfill subjected to the modified pseudodynamic earthquake loading. ...
Geotechnical Performance of Alkali-Activated Uncalcined Clayey Soils with Hydroxide- and Aluminate-Based Activators
Publisher: American Society of Civil Engineers
Abstract: This research evaluates the performance of two low- and high-plasticity clays as the sole precursors to develop alkaline activation at ambient temperature. NaOH solutions with different concentrations of 2 to 10 mol/L ...
