Finite-Strain Axial Analysis of Piles in Clay
In the late 1970's, a series of research projects developed simple effective-stress methods to predict the axial capacity of piles in normally-consolidated clay. The method...
Prediction of Settlement of Single Piles in Clay
Analyses by trial were used to fit theoretical load-settlement curves to measured curves for driven piles. For the elastic method, analyses of load tests indicated that designers should...
Dynamic Stiffness of Pile Groups
A number of procedures have been proposed for the dynamic analysis of complete pile foundations including group effects. Most of these introduce some sort of approximation to reduce the...
Winkler Soil Model for Axial Response Analysis of Pile Groups
In this approach, the soil is idealized as a nonlinear Winkler model for a pile group attached to a group of piles. The model can account for pile-soil-pile interaction. Pile group responses...
Relational Model for Computer Analysis and Design
One of the most critical elements in engineering analysis and design is data management. Relational database systems have been proven to be an excellent tool for managing the voluminous...
Advanced Graphical CAD System for 3D Steel Frames
An innovative, advanced graphical computer-aided design system, called STEEL-3D, is described. The main objective of this program is to provide the engineer with all the tools necessary...
Automated Analysis Model Generation
The state of development of the capabilities needed to automatically link the geometric definition of a CAD system to finite element analysis is discussed. Areas considered include fully...
Influence of Connection Behavior on Steel Frame Designs at Factored Loads
This paper illustrates how interactive computer graphics, when interfaced with nonlinear inelastic frame analysis programs, can provide a powerful tool for design of semi-rigid frames...
Consulting Engineers' Experience with CAD
A general, brief history of the role of computers in design in consulting engineering practice is presented. Their changing role from their initial early use to today's involvement...
Numerical Analysis of Two Embankment Foundations
Two case histories of the performance of a compressible embankment foundation are analyzed using the Cam-Clay constitutive model and a finite element consolidation program. The I-95 highway...
Consolidation-Strength Analysis for Soft Soils
A one-dimensional consolidation analysis including prediction of consequent shear strength increase for soft soils which exhibit large secondary compression is proposed. Consolidation...
The Use of Soil Mechanics Capabilities in a General Purpose Finite Element Program
This paper describes capabilities, points out features of implementation in a general purpose code, and describes some numerical considerations. The paper makes use of illustrative solutions....
Consolidation of Multi-layered Clay
Three kinds of clay with different plasticity were pre-consolidated from slurry and combined into typical two layered systems consolidated under 40 tf/m**2 with single drainage condition....
Yield Behaviour and Consolidation. I: Pore Pressure Response
This paper discusses the frequency of occurrence of anomalous consolidation behaviour. The behaviour of soft clay is discussed briefly in terms of the effective stress path/yield envelope...
Yield Behaviour and Consolidation. II: Strength Gain
In Part I it was shown that in situ yielding of soft foundation clays significantly affected consolidation behaviour and that yield could be defined using the effective stress path/yield...
Consolidation of Permafrost upon Thawing
Methods of predicting initial consolidation upon thawing and the subsequent consolidation with time under increasing pressures are presented in terms of changes in unit weight. Procedures...
Monitoring of an Ocean Dredged Material Disposal Site
The Tampa Harbor Project involves deepening and widening approximately 50 miles of existing shipping channel in Tampa Bay, Florida, with the removal of approximately 70 million cubic yards...
Computer Models for Dredged Material Disposal Planning
Short term and long term planning for the disposal of dredged material can be significantly enhanced using state-of-the-art computer modeling. Computerized mathematical models can be constructed...
Shoaling Problems and Improvements Sunny Point, North Carolina
The Military Ocean Terminal, Sunny Point (MOTSU), is located on the Cape Fear River, approximately 18 miles downriver from Wilmington, North Carolina. The facility has experienced significant...
