Rigid Spread Footings Resting on Soil Subjected to Axial Load and Biaxial Bending. I: Simplified Analytical Method
(American Society of Civil Engineers, 2013)A simplified analytical method that determines the axial load and biaxial moment capacities of a rigid spread footing of regular or arbitrary shape resting on soil is presented. Three different types of pressure distribution ... -
Estimating In Situ Deformation of Rock Masses Using a Hardening Parameter and RQD
(American Society of Civil Engineers, 2013)This study explores the utility of a pressure-dependent empirical hardening parameter in estimating deformation of rock masses. The hardening parameter has drawn poor attention in classical rock mechanics. Review of previous ... -
Y-Geo: New Combined Finite-Discrete Element Numerical Code for Geomechanical Applications
(American Society of Civil Engineers, 2012)The purpose of this paper is to present Y-Geo, a new numerical code for geomechanical applications based on the combined finite-discrete element method (FDEM). FDEM is an innovative numerical technique that combines the ... -
Resilient Modulus Modeling with Information Theory Approach
(American Society of Civil Engineers, 2013)Statistical models have been developed to correlate resilient modulus with routine properties of subgrade soils and state of stress for pavement design application. An information theory approach is taken as a method in ... -
LRFD Calibration of the Ultimate Pullout Limit State for Geogrid Reinforced Soil Retaining Walls
(American Society of Civil Engineers, 2012)The results of load and resistance factor design (LRFD) calibration are reported for the pullout limit state in geogrid reinforced soil walls under self-weight loading and permanent uniform surcharge. Bias statistics are ... -
Investigation on the Effect of Data Imbalance on Prediction of Liquefaction
(American Society of Civil Engineers, 2013)Data imbalance causes learning bias in class identification techniques. A major cause for limited success in the prediction of liquefaction potential by various pattern recognition techniques is because of a liquefaction ... -
Settlement Calculation of Composite Foundation Reinforced with Stone Columns
(American Society of Civil Engineers, 2013)An axial compression was generated in a stone column under vertical loads on its top, and was often accompanied by a radial expansion against the surrounding soil near the top portion of the column. Considering this ... -
Physical Basis and Validation of a Constitutive Model for Soil Shear Derived from Microstructural Changes
(American Society of Civil Engineers, 2013)Previous work indicated that rates of change of shear stress, effective normal stress, and void ratio of a sheared soil are proportional to applied values of shear and effective normal stress; initial proportionality values ... -
Bearing Capacity of Piles in Soft Clay Underlaid by Cohesive Frictional Soil
(American Society of Civil Engineers, 2013)By using the axisymmetric quasi-lower bound finite-element limit analysis, the bearing capacity factors -
Fastest Rapid Loading Methods of Vertical and Radial Consolidations
(American Society of Civil Engineers, 2013)Fastest curve-fitting procedures are proposed for vertical and radial consolidations for rapid loading methods. In vertical consolidation, the next load increment can be applied at 50–60% consolidation (or even earlier if ... -
Rigid Spread Footings Resting on Soil Subjected to Axial Load and Biaxial Bending. II: Design Aids
(American Society of Civil Engineers, 2013)Design aids (nomograms) for rectangular and symmetrical trapezoidal rigid spread footings are developed using a method previously developed by the writers in a companion paper. The nomograms can be used by designers to ... -
