Abstract: Analytical expressions for soil stiffness for a group of piles were obtained for both plane strain and three‐dimensional conditions. A comparison between these two expressions revealed that a concept of a Winkler soil model ...

Abstract: A simple mechanical model is developed for the dynamic response analysis of a layered soil medium. Each layer in the medium is idealized as a system of one‐dimensional vertical elastic columns interconnected by the shear ...

Abstract: Consolidation of inhomogeneous clay with a system of horizontal and vertical drains is considered. Horizontal drains in the system are made of multiple thin pervious layers such as sand layers and geotextile sheets, while ...

Abstract: Nonlinear conditions are implemented in the time domain formulation for the dynamic response of pile foundations previously developed by the writers. Both single and group piles subjected to vertical dynamic load are ...

Abstract: Based on a combination of the conventional limit equilibrium approach and Lagrange's indeterminate multiplier procedure, a generalized limit equilibrium method is developed by using the variational technique. The fundamental ...

Abstract: A procedure for the time domain analysis of axial single pile response is developed. A time domain soil‐pile interaction force is formulated through a simple mechanical idealization of the soil medium, developed from the ...

Abstract: Adopting a Winkler assumption, a simple mechanical soil model is developed for the flexural response analysis of dynamically loaded piles. The model is defined by examining a frequency‐domain analytical expression obtained ...

Abstract: The lateral cyclic response of a pile foundation is formulated by treating the subgrade as a viscoelastic Winkler model for simplicity. Viscoelastic characterization of the model is convenient for the computation of a ...

Abstract: A procedure for the time‐domain analysis of axial pile group response is developed. A pile‐soil‐pile interaction force is formulated in the time‐domain based on a previously developed dynamic, frequency‐domain Winkler model ...

Abstract: A simplified approach for the analysis of the static axial response of pile groups is presented. The approach is based on idealization of the soil around pile shafts as a “Winkler Model for Pile Group” and a transfer matrix ...
