Unified Expression of Rotational Hardening in Clay Plasticity
(American Society of Civil Engineers, 2016)Rotational hardening is the constitutive ingredient of clay plasticity models that allows rotation of the yield surface in stress space to simulate, more realistically than isotropic models, the stress-strain response under ... -
New Method for a Beam Resting on a Tensionless and Elastic-Plastic Foundation Subjected to Arbitrarily Complex Loads
(American Society of Civil Engineers, 2016)Many soil-structure interaction problems can be idealized as foundation beam problems. In the present work, the tensionless contact problem of an Euler-Bernoulli beam of finite length resting on an elastic-plastic foundation ... -
Suction-Induced Hardening Effects on the Shear Modulus of Unsaturated Silt
(American Society of Civil Engineers, 2016)The small-strain shear modulus -
Numerical Analysis of Low-Fill Box Culvert under Rigid Pavement Subjected to Static Traffic Loading
(American Society of Civil Engineers, 2016)This paper presents a numerical study on culverts under rigid pavements subjected to static traffic loading. The numerical study was based on the results of a comprehensive field study of a single-cell low-fill box culvert ... -
Inversion of Critical Slip Surface Parameters for a Landslide Disaster Using the Bionics Algorithm
(American Society of Civil Engineers, 2016)Two key issues in landslide forecasting are finding the critical slip surface and determining its parameters. Generally, these issues are two parts of one problem. To solve this problem, a new two-phase search method is ... -
TBM–Block Interaction during TBM Tunneling in Rock Masses: Block Classification and Identification
(American Society of Civil Engineers, 2017)A new block-classification method for tunnel construction using a tunnel-boring machine (TBM) to capture the geometrical and mechanical transformation of rock blocks in the course of TBM excavation is proposed in this ... -
Strength and Dilatancy Behaviors of Dense Modeled Rockfill Material in General Stress Space
(American Society of Civil Engineers, 2016)The strength and dilatancy behaviors of modeled dense rockfill material were systematically investigated through a series of true triaxial compression tests at different minor principal stress and intermediate principal ... -
Disturbed State Concept-Based Constitutive Model for Lignosulfonate-Treated Silty Sand
(American Society of Civil Engineers, 2015)In this paper, a new behavioral (plasticity) model for lignosulfonate (LS)–treated silty sand based on the disturbed state concept is proposed. Here, the relative intact (RI) responses for both the LS-treated and untreated ... -
Behavior of Geosynthetic Reinforced Soil Foundation Systems Supported on Stiff Clay Subgrade
(American Society of Civil Engineers, 2016)A series of laboratory model tests was performed to investigate the behavior of geosynthetic reinforced stiff clay foundation systems under circular loading. The footing consisted of a rigid circular steel plate with a ... -
Mixed FEM–Crushable DEM Nested Scheme in Second-Order Computational Homogenization for Granular Materials
(American Society of Civil Engineers, 2016)A mixed FEM–crushable discrete-element method (DEM) nested scheme in the frame of second-order computational homogenization for granular materials was proposed. The particle breakage followed by the discontinuity and ... -
Pore Water Pressure Response of Soil Subjected to Dynamic Loading under Saturated and Unsaturated Conditions
(American Society of Civil Engineers, 2016)This study presents the results of one of the first attempts to characterize the pore water pressure response of soils subjected to dynamic loading under saturated and unsaturated conditions. The resilient modulus, which ... -
Microstructure-Based Effective Stress Formulation for Unsaturated Granular Soils
(American Society of Civil Engineers, 2016)The principle of effective stress states that the strength and volume change behaviors of soil are governed by intergranular forces expressed in terms of a continuum quantity called effective stress. Although the principle ... -
Use of a Dual-Structure Constitutive Model for Predicting the Long-Term Behavior of an Expansive Clay Buffer in a Nuclear Waste Repository
(American Society of Civil Engineers, 2016)Expansive soils are suitable as backfill and buffer materials in engineered barrier systems to isolate heat-generating nuclear waste in deep geological formations. The canisters containing nuclear waste would be placed in ... -
