Using Wood as Structural Material: Some Environmental Considerations
Against a background of growing public awareness of the potential dangers of global warming resulting from increasing concentrations of carbon dioxide in the atmosphere it is suggested...

Use of Pressuremeter in Mixed Highrise Foundation Design
The pressuremeter has been used extensively for the evaluation of strength and deformation characteristics of the glacial hardpan soils in the design and construction of caisson foundations...

Driven Then Pushed Minicone Tests in a Sand Chamber
For a general knowledge on the Standard Cone Penetrometer test and its uses the reader is referred to the work of Briaud and Miran (1991). For this study (Khalaf and Briaud, 1992) a smaller...

Verification of Deep Foundations by NDT Methods
Deep foundations are designed using static analysis techniques and the soil strength and structural integrity are then confirmed by static load tests. However, static tests are time consuming...

3-D Deformation Analysis of Pile Groups During Wave Loading
Deformation predictions of pile group supporting one leg of Magnus platform were conducted using the 3-D nonlinear computer program SPLICE (Structure/Pile/Soil Interaction Analysis) and...

Evaluation and Monitoring of Pile Performance Using Dynamic Measurements in Supporting Offshore Structures
The installation of offshore platforms into deeper waters and new environments is accompanied by an increasing uncertainty in the structure response, foundation design and performance....

A Centrifuge and Analytical Study to Evaluate Suction Caissons for TLP Applications in the Gulf of Mexico
This paper documents the results of a combined centrifuge and analytical study to evaluate the behavior of steel suction caissons under loading and soil conditions typical of deepwater...

Drilled Shaft Side Resistance in Clay Soil to Rock
An evaluation is made of available field load test data for the axial side clay soils to hard rocks. Conventional total stress interpretations by the alpha method are used to examine the...

Execution and Evaluation of High Capacity Caisson Load Tests in Glacial Deposits
As part of the Boston Harbor clean up project, the new 1,000 mgd Deer Island Sewerage treatment plant includes ten 240 feet high egg-shaped 'residuals' tanks. Contract documents called...

On the Elasto-Plastic Behavior of an Unsaturated Silt
Due to technical difficulties related to the control and measurement of the suction in unsaturated soils, few experimental data on the mechanical behavior of those soils exits. The paper...

Elasto-Plastic Volume Change of Unsaturated Compacted Clay
Isotropic compression tests were performed on samples of unsaturated compacted kaolin in a modified triaxial cell that allowed separate control of pore water pressure and pore air pressure....

One and Three Dimensional, Three Phase Deformation in Soil
An initially saturated soil exhibits two distinct deformation patterns as it drys. First, it deforms vertically until the soil begins to drain. Secondly , it deforms laterally as well...

Permeability Determination for Unsaturated Soils
A reliable approach for the determination of the soil hydraulic conductivity function relies on the parameter estimation solution approach in which heterogeneous state of saturation within...

HUD Concerns: Post-Tensioned Foundations in Texas
An investigation was conducted of post-tensioned slab foundation systems in Texas pursuant to a request from the Headquarters Office's of the U.S. Department of Housing and Urban Development...

Performance of Horizontal and Vertical Barriers
Horizontal and vertical barriers have been used on transportation facilities to control expansive soils and minimize their damages. The effort is to minimize moisture change in the soil...

Data Base for the Design of Piers in Expansive Soils
The paper describes the parameters and the structure of the seed of a data base of properties and observed field behavior of expansive soils assembled from an extensive literature review....

The Use of Structural Composites in 21st Century Infrastructure Technology
The purpose of this paper is to create and transmit a sense of the unique benefits which effective application of composites technology can bring to the civil engineering. infrastructure...

Pultruded Composites: Materials for the 21st Century
The main objective of this paper is to introduce pultruded composites to the civil engineers and to create the awareness of its important applications. A description of the pultrusion...

21st Century Composites Require ASCE Standards and SDS
This paper describes the ASCE initiative and discusses the philosophy and needs for the structural design system (SDS) of which the standards will be a part. Our perspective is from the...

Composite Construction in Steel and Concrete II
Composite steel-concrete structures are widely used throughout the world. Applications range from buildings to bridges to foundations to special structures. In many instances extensive...
