Plastic Piling
Composite plastic and steel piles are gaining acceptance throughout the United States. The evolving technology has produced a unique product which solves several problems related to use...

Design of Pile Foundations
This handbook, Design of Pile Foundations, provides information on foundation exploration and testing procedures, load test methods, analysis...

Vertical Erosion on Beaches and the National Flood Insurance Program
During the 25 years that the National Flood Insurance Program (NFIP) has been in existence, there has been an increasing recognition of the contribution of both episodic and long-term...

The Influence of Exposed Footings on Pier Scour Depths
Data compiled from past test efforts are combined in this article with the results of two new flume test studies. The combined material, presented graphically, suggests a method for adjusting...

Methods for Prediction of Maximum Scour at Coastal Structures
The most common coast scour-related problems are toe scour at rubble mound structures and vertical seawalls, and scour at the base of piles and horizontal pipelines. Existing scour prediction...

Connection of Grouted Tubular Insert Piles to Soil
Force transfer between offshore production jackets and tubular piles is effected by weld bead shear connectors, acting within the grout filled annulus between the piles and pile sleeves...

The Connecting Method of Steel and Concrete Using Long Deformed Bar Studs
A new welding technique for long horizontal studs of 19 mm and 22 mm diameters was established. The transmission of shearing and bending forces was evaluated using large model tests. Actual...

Pin Piles Save Silos
The United Grain Corp. annually ships about 200 million bushels of wheat and other grains to destinations around the world from its leased facility on the Columbia River at Vancouver,...

Evaluation of Dilatometer Method to Determine Axial Capacity of Driven Model Pipe Piles in Clay
The flat Dilatometer (DMT) provides a unique approach to estimate the effective stress axial capacity of driven displacement piles in clay. An investigation using this approach was performed...

Piles for Marquette University Math Building
This paper presents a comparison of static pile capacity predictions using CPT cone resistance results with results of a test pile program and production pile driving. Pile capacity prediction...

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....

Behavior of Suction Piles in Sand
In the marine environment, use of suction pressure for the installation of sealed top piles (suction piles) is a promising alternative to driven pile foundations, particularly in deep...

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...

Negative Skin Friction Due to Wetting of Unsaturated Soil
A steel building at a cement plant un Utah was originally supported by spread footings. Shallow wetting of the coarse granular soils supporting the footings resulted in over three inches...

Design and Performance of Deep Foundations
Piles and Piers in Soil and Soft Rock
This proceedings, Design and Performance of Deep Foundations: Piles and Piers in Soil and Soft Rock, consists of papers presented at five sessions...

Skin Friction Distrtibutions on Piles in Sand
Presented in this paper are early results from an analytical investigation of the performance of a closed-ended pipe pile under monotonic axial loading in dense sand. The study was performed...

Review of API Guidelines for Pipe Piles in Sand
Most offshore structures are supported using steel pipe piles which are designed in accord with API Recommended Practice 2A. The guidelines for analysis of axial capacity of steel pipe...

Piles Under Dynamic Loads
This proceedings, Piles Under Dynamic Loads, consists of papers that try to identify the state of practice in the analysis and design of pile...

The Caisson Solution
Detroit is expanding its wastewater treatment plant to drastically reduce combined sewer overflows. The expansion, however, is being done on an extremely congested 4 acre tract of land...
