Structures for Enhanced Safety and Physical Security
This book presents the state-of-the-art in the general subject of structures for enhanced safety and physical security. The technical papers written are by engineers and researchers who...
Tension Leg Platform
a State of the Art Review
Prepared by the Task Group on Compliant Offshore Platforms of ASCE. This report considers the analysis and design of tension leg platforms (TLPs),...
Influence of Geologic Development on Horizontal Stress in Soil
Geologic history commonly controls the stress in natural soils, so that an understanding of the geology allows an assessment of the horizontal stress. This paper describes mechanistically...
Cyclic Behavior of Natural Overconsolidated Clay in Two Loading Modes
One-way, stress-controlled, cyclic triaxial compression tests were conducted on a heavily overconsolidated (Ko > 1), slickensided, natural clay with a view to modeling its cyclic...
Characterization of a Site Underlain by Deep Collapsing Soils
The geomorphic setting of a site underlain by an 80 ft (24 m) deep deposit of collapsing silty sand is described. The field and laboratory investigation completed to characterize the geotechnical...
Helical Bearing Plate Foundations for Underpinning
Helical anchor foundations have been used in construction to provide resistance against uplift and compressive loading for structures such as transmission towers, tied walls, pipelines,...
Design and Construction of Stone Column Reinforced Cofferdams
A recent expansion of the North Carolina State Port Facility, at Wilmington, involved the use of six cellular cofferdams as earth retaining structures during dredging and final filling...
Concrete Removal Techniques with Potential for Use in Rock
This paper describes concrete removal techniques that were employed in the rehabilitation of US Army Corps of Engineers mass concrete structures and are thought to have potential for limited...
Static Behavior of Piles in Cemented Calcareous Sands
A series of instrumented jacked model pile tests and another series of uninstrumented grouted model pile tests in a cemented calcareous sand were performed. The influence of pile installation...
Investigation and Modeling of Soil-Structure Interface Properties
An investigation of some techniques suggested to reduce friction at the soil-structure interface, for example plastic sheet on sand, is presented, and a model proposed for characterizing...
Fact or Friction: A Review of Soil Response to a Laterally Moving Pile
A review of soil response around a laterally moving pile is presented and 'Winkler' spring soil modulus variations are discussed. Based on available theory, and...
Subgrade Models for Soil-Structure Interaction Analysis
Historical development of improvements to Winkler's spring subgrade model are traced. The improvements consist of various ways to provide shear coupling between the springs....
Numerical Analysis of Vertically Loaded Pile Groups
An approach is presented for the analysis of linear and nonlinear response of vertically loaded pile groups. The piles are modeled with finite elements, the pile-soil influence through...
Transient Dynamic Response Analysis of Embedded Rigid Foundations
A simplified approach for the transient dynamic response analysis of embedded multiple rigid foundations is presented. The approach is based on approximate time-domain formulations of...
Subgrade Model for Static and Dynamic Response Analysis of Surface Foundations
A new subgrade model is presented for the static and dynamic response analysis of surface foundations. The model consists of a number of horizontal layer model units. Each model unit is...
Foundation Studied for Turbine-Generator on Liquefiable Soils
Turbine-generator foundations are generally constructed of concrete in the U.S.A. This paper deals with the dimensioning and evaluation of a turbine foundation in Oxnard, California. The...
Effect of Site Soil Properties on Seismic SSI Response of Embedded Structures
In a series of two-dimensional soil-structure interaction (SSI) analyses, seismic responses, including the SSI effect of a deeply embedded reactor building of a standard plant in different...
Uncertainties in Offshore Axial Pile Capacity
The overall bias and error associated with the API recommended procedures and other popular methods for offshore pile design are evaluated. The paper considers single axial friction piles...
Movement Control of Excavation Support Systems by Iterative Design
Conventional design practice for excavation support systems emphasizes determination of loads and selection of structural components. This paper presents a method which uses movement control...
Some Expert System Applications in Geotechnical Engineering
Knowledge-based expert systems (KBES) represent a new technology for computer-aided engineering. These systems can be useful in situations which involve expert judgments for effective...
