Nonstationary Shear-Wave Velocity Randomization Approach to Propagate Small-Scale Spatial Shear-Wave Velocity Heterogeneities into Seismic Response
(American Society of Civil Engineers, 2024)Recent studies in earthquake engineering have outlined the difficulty of ground response analyses (GRAs) to replicate the observed ground motion and related variability at borehole array sites. Improvement of the seismic ... -
Physical Modeling of Hydrate Dissociation in Sandy Sediment by Depressurization under Hypergravity and Normal Gravity Conditions
(American Society of Civil Engineers, 2024)Geomechanical and heat transfer characteristics of gas hydrate-bearing sediment (GHBS) are significantly affected by hydrate dissociation during gas production from reservoirs, which is typically tens of meters in thickness. ... -
Multifidelity Data Fusion for the Estimation of Static Stiffness of Suction Caisson Foundations in Layered Soil
(American Society of Civil Engineers, 2024)The static stiffness of suction caisson foundations is an important engineering factor for offshore wind foundation design. However, existing simplified design models are mainly developed for nonlayered soil conditions, ... -
A Novel Method for Integrity Assessment of Soil-Nailing Works with Actively Heated Fiber-Optic Sensors
(American Society of Civil Engineers, 2024)Soil nailing has become a common method for improving slope stability due to its cost-effectiveness and easy installation. However, concerns have been arisen regarding the quality and integrity of soil nailing works. This ... -
Generic Models for Predicting Coseismic Displacements of Earth Slopes Based on Numerical Analysis and Machine Learning Algorithm
(American Society of Civil Engineers, 2024)Generic models for estimating the earthquake-induced displacement of Earth slopes are developed based on a numerical approach. A number of 14,112 slope models with different configurations of slope geometry and soil property ... -
Lateral Response of a Single Pile in Unsaturated Sand
(American Society of Civil Engineers, 2024)Pile response in unsaturated soils is an area of interest due to its prevalence in real-world scenarios. Significant differences exist in the lateral behavior of single piles in partially saturated soils due to increased ... -
Wildfire Ash Composition and Engineering Behavior
(American Society of Civil Engineers, 2024)After a wildfire event, ash is a newly formed surficial soil layer with microscale properties such as roughness, morphology, and chemical composition that may impact how ashes form fabrics in situ and so affect the overall ... -
Numerical Investigation of the Capacity of Anchor Chain Links in Clay
(American Society of Civil Engineers, 2024)Offshore floating systems are held in position with chains that connect the floater to anchors embedded in the seabed. An essential component for calculating the overall mooring capacity is an accurate assessment of the ... -
Aging Factors for the Cyclic Resistance Ratio of Pleistocene Sands from the South Carolina Coastal Region
(American Society of Civil Engineers, 2024)Laboratory and field tests were performed on sandy soils from six Pleistocene-age sites in the South Carolina coastal region to investigate the age-related resistance to liquefaction. Stress-controlled cyclic triaxial tests ... -
Nondestructive Evaluation of Pile Length for High-Mast Light Towers
(American Society of Civil Engineers, 2024)Records of pile lengths are not available for several hundred high-mast light towers (HMLTs) throughout the state of Minnesota. The foundation systems, typically steel H-piles or concrete-filled steel pipe piles connected ... -
Energy-Based and Strain-Based Methods for Estimation of Pore Water Pressure within Liquefied Soil Layers
(American Society of Civil Engineers, 2024)The evaluation of the excess pore water pressure ratio (ru), the ratio of the excess pore water pressure of the soil, is a defining approach to assessing liquefaction occurrence. Rarely is ru measured, so surficial ... -
A Parametric Study on the Effect of Drainage on Sand Liquefaction under High Overburden Pressure
(ASCE, 2024/03/01)The effect of high overburden pressure above 1 atm on sand liquefaction potential is typically evaluated based on cyclic undrained testing, with the overburden pressure correction factor, Kσ<1.0 and Kσ decreasing ... -
