RISBehavior of Ring Footing on Two-Layered Soil due to Various Loading Positions
Publisher: ASCE
Abstract: The primary focus of the present article is to evaluate the bearing capacity of ring footing placed over two-layered soils and subjected to vertical loadings applied over certain portions of the footing, namely, inner half, ...
Combined Effect of Non-Darcian Flow and Semipermeable Drainage Boundaries on One-Dimensional Consolidation of Unsaturated Soil
Publisher: American Society of Civil Engineers
Abstract: The present article aims to understand the consolidation of unsaturated soil enclosed by semipermeable drainage boundaries and subjected to nonlinear water flow. The transient process of fluid flow is governed by the ...
Bearing Capacity Factors for Ring Foundations
Publisher: American Society of Civil Engineers
Abstract: Bearing capacity factors because of the components of cohesion, surcharge, and unit weight, respectively, have been computed for smooth and rough ring footings for different combinations of
Lower-Bound Axisymmetric Formulation for Geomechanics Problems Using Nonlinear Optimization
Publisher: American Society of Civil Engineers
Abstract: A lower-bound limit analysis formulation, by using two-dimensional finite elements, the three-dimensional Mohr-Coulomb yield criterion, and nonlinear optimization, has been given to deal with an axisymmetric geomechanics ...
Seismic Bearing Capacity of Rough Strip Footing Placed Over Geogrid-Reinforced Two-Layer Sands
Publisher: ASCE
Abstract: The lower bound limit theorem in conjunction with finite elements is used to quantitatively estimate the pseudostatic bearing capacity of a rough strip footing placed on geogrid-reinforced sandy soil. The objective of this ...
Upper-Bound Axisymmetric Limit Analysis Using the Mohr-Coulomb Yield Criterion, Finite Elements, and Linear Optimization
Publisher: American Society of Civil Engineers
Abstract: An upper-bound limit analysis formulation has been presented for solving an axisymmetric geomechanics stability problem using the Mohr-Coulomb failure criterion in conjunction with finite elements and linear programming. ...
Upper-Bound Bearing Capacity of Strip Footings Rested on Unsaturated Sands and Subjected to Eccentric and Inclined Loading
Publisher: American Society of Civil Engineers
Abstract: This article deals with the load-bearing capacity of strip foundations resting on unsaturated sands and subjected to eccentric and inclined loading. The numerical simulations are performed by modifying the conventional ...
Disturbance Modeling and Prediction of ClosedLoop MicroActuator Stroke Usage in DualStage Hard Disk Drives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This letter presents a method to model the disturbance environment of a dualstage hard disk drive (HDD), which is then used to predict the actuator stroke usage (i.e., the range of actuator displacement used) of a closedloop ...
Stability of Unsupported Vertical Circular Excavations
Publisher: American Society of Civil Engineers
Abstract: A methodology has been presented for determining the stability of unsupported vertical cylindrical excavations by using an axisymmetric upper bound limit analysis approach in conjunction with finite elements and linear ...
