LRFD Resistance Factors for Base-Grouted Drilled Shafts in Cohesionless Soil
(American Society of Civil Engineers, 2025)Base grouting below a drilled shaft tipped in sand has been shown in many cases to dramatically improve both the initial stiffness and ultimate end-bearing resistance. After promising results from base-grouting case studies ... -
Threshold of Cyclic Phenomena
(American Society of Civil Engineers, 2025)Granular materials subjected to cyclic loading are characterized by changes in their shear modulus, pore water pressure, and volume. These changes occur when the amplitude of the cyclic shear strain exceeds the cyclic ... -
Experimental Investigation of Rate Effects on the Uplift Response of Surface and Skirted Circular Shallow Foundations
(American Society of Civil Engineers, 2025)Shallow foundations can mobilize uplift resistance due to the negative excess pore pressure generated underneath the foundation. However, quantifying the magnitude of this uplift resistance remains uncertain due to the ... -
Evaluation of the Performance of Hybrid Geosynthetic–Reinforced Soil Walls Subjected to Rainfall in a Geotechnical Centrifuge
(American Society of Civil Engineers, 2025)In the present study, the centrifuge modeling approach was utilized to investigate the efficacy of dual-functional hybrid geosynthetics as reinforcement in alleviating the destabilizing effects of rainfall on geosyntheti ... -
Mitigation of Liquefaction Damage to Shallow-Founded Structures with In-Ground Structural Walls
(American Society of Civil Engineers, 2025)Stiff in-ground structural or diaphragm walls have previously been used as a liquefaction countermeasure for existing building structures. The available design methodologies for typical mitigation techniques are based on ... -
Progressive Response and Dynamic Behavior of Loose Gravel–Sand Mixtures
(American Society of Civil Engineers, 2025)Previous studies investigating dynamic responses of gravelly soil were limited to high-strain conditions, in which a high level of pore-water pressure is developed, leading to a significant reduction in shear strength and ... -
Pressure-Cycled Installation of Suction Buckets in Sand and Layered Soil Profiles
(American Society of Civil Engineers, 2025)Installation refusal is a key design consideration for suction buckets. Pressure cycling, whereby the bucket is cycled vertically by reversing the pump flow, has been identified as one of the potential strategies to overcome ... -
Pressure Cycling of Suction Buckets in Clay
(American Society of Civil Engineers, 2025)Suction buckets are being increasingly considered as foundations for offshore wind turbines, as they can be installed by pumping water from the interior of the bucket, minimizing acoustic emissions. A key design consideration ... -
Estimation of Timing of Liquefaction Using Spectral Energy Ratio
(American Society of Civil Engineers, 2025)The significant reduction in the stiffness of liquefied soil is accompanied by a decrease in the shear wave velocity, which ultimately results in the softening of the liquefied site. Time–frequency response analysis can ... -
Numerical Study on Blast Dynamic Response of Jointed Rock Mass under High Geostress Field
(American Society of Civil Engineers, 2025)To study the blast-induced dynamic response of jointed rock mass under high geostress field, a numerical model for the blast in the jointed rock mass was first established based on Ansys LS-DYNA software and the ... -
Normalized Shear Modulus and Material Damping Model for Southeastern US Residual Soil and Saprolite
(American Society of Civil Engineers, 2025)This paper presents the development of a new normalized shear modulus and material damping model for southeastern US residual soil and saprolite. The model is based on other investigators’ resonant column and torsional ... -
Analytical Solutions for Lateral Bearing Capacity of Piles in Nonhomogeneous Soil
(American Society of Civil Engineers, 2025)In routine design, the lateral bearing capacity of a single pile is commonly evaluated using analytical expressions which are derived under the hypothesis of rigid-plastic behavior of both the foundation soil and the pile ... -
An Improved CRR-Vs1 Characterization Model for Sand-Like Gravelly Soils Validated by Dynamic Centrifuge Tests
(American Society of Civil Engineers, 2025)Liquefaction of natural deposited sand-like gravelly soils has been widely reported in past earthquakes. Assessing the liquefaction resistance (CRR) of sand-like gravelly soils in a cost-effective and reliable way raises ... -
Efficiency and Characteristics of MICP in Environments with Elevated Salinity, Diminished Oxygen, and Lowered Temperature: A Microfluidics Investigation
(American Society of Civil Engineers, 2025)Microbially induced carbonate precipitation (MICP) shows significant potential for improving soil strength, but environmental factors greatly influence its mechanisms and effectiveness. The feasibility of using MICP in ... -
Axial and Circumferential Behavior of Rock-Socketed FRP-SSC Composite Piles Monitored by Distributed Optical Fiber Sensors
(American Society of Civil Engineers, 2025)Traditional pile foundations in harsh marine environment may experience steel corrosion or concrete deterioration. Besides, conventional measuring devices such as strain gauges and vibrating wire extensometers are sensitive ... -
