RISNonlinear Seismic Response Analysis of Pile Foundations Interacting with Improved and Unimproved Soft Clay
Publisher: American Society of Civil Engineers
Abstract: Several ground improvement techniques, which have been proven to be effective and economical solutions for increasing the lateral stiffness and strength of weak soils around piles, can often result in unnecessarily ...
Analysis of Laterally Loaded Pile Groups in Improved Soft Clay
Publisher: American Society of Civil Engineers
Abstract: The use of p-multipliers in the analysis of the lateral loading behavior of pile groups is based on the concept of modifying the single-pile p-y curve to obtain the p-y curve for a pile in a group. The p-multipliers account ...

Level Ground Soil‐Liquefaction Analysis Using in Situ Properties: I
Publisher: American Society of Civil Engineers
Abstract: Based on Maxwell's pioneering work, on the electrical conduction through heterogeneous media a fundamental approach utilizing the electrical properties of soils to characterize their grain (particle shape) and aggregate ...
Level Ground Soil‐Liquefaction Analysis Using in Situ Properties: II
Publisher: American Society of Civil Engineers
Abstract: Current methods for level ground soil‐liquefaction analysis involve the use of a stress ratio required to cause liquefaction obtained from laboratory testing of small element samples. Limited field evidence and considerable ...
Coupled Hydro-Mechanical Elastoplastic Constitutive Model for Unsaturated Sands and Silts. I: Formulation
Publisher: American Society of Civil Engineers
Abstract: Unsaturated soils are three-phase porous media consisting of a solid skeleton, pore water, and pore air. The behavior of unsaturated soils is strongly influenced by the matric suction (pore air pressure minus the pore water ...
Coupled Hydro-Mechanical Elastoplastic Constitutive Model for Unsaturated Sands and Silts. II: Integration, Calibration, and Validation
Publisher: American Society of Civil Engineers
Abstract: Following the comprehensive model formulation given in Part I, a fully implicit integration procedure for the rate equations using a closest point projection method is presented in this paper. The stress-update algorithm ...
Liquefaction of Level Ground Unsaturated Sand Deposits Using a Validated Fully Coupled Analysis Procedure
Publisher: American Society of Civil Engineers
Abstract: Liquefaction of unsaturated sands has been observed in laboratory tests and in the field. A comprehensive investigation of unsaturated sand deposits subjected to seismic loading, especially using validated computational ...
Seismic Response of Soil Deposits in San Francisco Marina District
Publisher: American Society of Civil Engineers
Abstract: This paper presents an application of the effective stress based, fully coupled, nonlinear numerical procedure DYSAC2 and the total stress-based, equivalent-linear procedure SHAKE to the analysis of the seismic response ...
Liquefaction of Unsaturated Sands
Publisher: American Society of Civil Engineers
Abstract: Recent laboratory tests and field observations have revealed that unsaturated sands are susceptible to liquefaction. Systematic investigation of liquefaction potential of unsaturated sands is, however, lacking. In this ...
