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...
Analysis of Local Scour at Bridge Piers
Many studies have been performed on the cause and effects of local scour at bridge piers, and various prediction equations have been generated based on these studies. The general approach...
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,
Naval Pier Foundation Design and Construction, Pearl Harbor, Hawaii
The paper presents a case study of foundation design and construction for a pier in Pearl Harbor. The study covers a review of site investigations, laboratory testing, pile selection and...
Piles Over Problems Sites
It's increasingly difficult to find suitable space for construction in urban areas. Pile foundations can fill the void by making questionable and heavily regulated sites,...
Dynamic Response Analysis of Pile Foundations by Using Variational Calculus
Various approaches have been developed for the frequency-domain dynamic response analysis. The one proposed by M. Novak (1974) is simplest of all and yet produces the results very close...
Failure Prediction of Anisotropic Material
Basic mathematical elements of a higher order failure theory for anisotropic material are outlined. Surface closure is ensured by requiring a tensor polynomial to satisfy constraint conditions....
Offshore Pile System Reliability
The existing design methodology for offshore pile foundations is evaluated relative to the ultimate performance of the foundation system using reliability techniques and data from three...
Gate Maritime Wharf and Intermodal Facility
Gate Maritime Properties (GMP) is a small private port located in Jacksonville, Florida. In November of 1989, Gate signed a long-term lease agreement with the U.S. Department of the Navy...
