Bearing Capacity and Settlement of Skirted Shallow Foundations on Sand
(American Society of Civil Engineers, 2013)The behavior of axially loaded skirted shallow foundations resting on sand was studied using an extensive numerical analysis. Surface, pier, and skirted square foundations resting on sand with different shear strength ... -
Dispersion of Love Wave Propagating in Irregular Anisotropic Porous Stratum under Initial Stress
(American Society of Civil Engineers, 2013)Propagation of a Love wave in an initially stressed fluid-saturated anisotropic porous layer with an irregular boundary sandwiched between two isotropic half-spaces has been studied. The irregularity is assumed to be ... -
Applications of Finite/Discrete Element Modeling to Rock Engineering Problems
(American Society of Civil Engineers, 2013)In this paper, the authors review recent applications of an integrated numerical modeling approach based on the analysis of the mechanical behavior of discrete systems. The numerical analysis includes both a more realistic ... -
Detection of Shallow Anomalies in Pile Integrity Testing
(American Society of Civil Engineers, 2013)When an impact source is applied to the top of a pile, the waves near the top exhibit strong three-dimensional characteristics. When an anomaly is locally distributed near the top of the pile (shallow anomaly), there are ... -
Numerical Modeling of Piles in Collapsible Soil Subjected to Inundation
(American Society of Civil Engineers, 2013)Collapsible soil exhibits considerable strength when it is dry, but when it is inundated, it loses its strength and experiences significant volume reduction. Foundations on collapsible soils subjected to inundation may ... -
Estimation of Tensile Strength of Soils from Penetration Resistance
(American Society of Civil Engineers, 2013)Tensile strength of soil plays a decisive role in formation/initiation of cracks and their propagation, and its knowledge is essential to study and analyze the stability of earth-fill dams, slopes, embankments, highways, ... -
Numerical Study of Behavior of Anchor Plates in Clayey Soils
(American Society of Civil Engineers, 2013)This paper presents numerical models and mathematical formulations to predict the pullout capacity of anchor plates with different inclination angles embedded in clay. The models were developed based on the failure mechanism ... -
Seismic Behavior of Building Frames Considering Dynamic Soil-Structure Interaction
(American Society of Civil Engineers, 2013)The seismic excitation experienced by structures is a function of the earthquake source, travel path effects, local site effects, and soil-structure interaction (SSI) influences. The result of the first three of these ... -
Three-Dimensional Finite-Element Method for Soil-Building Interaction Based on an Input Wave Field
(American Society of Civil Engineers, 2013)A three-dimensional (3D) FEM for examining the soil-building interaction based on an input seismic wave field is proposed. A seismic wave field means seismic waves propagating in a 3D medium. An input seismic wave field ... -
Behavior of Single Pile in Liquefied Deposits during Earthquakes
(American Society of Civil Engineers, 2013)Analysis of pile foundations for earthquake loads requires the consideration of inertial loads that result from the soil-pile-superstructure interaction, as well as the evaluation of kinematic interactions that result from ... -
