Load Testing of Permanently Cased Drilled Shafts Founded in Hartford Shale
The axial and lateral load testing of three, 30 inch (76cm) diameter, permanently cased drilled shafts is analyzed herein. The prototype shafts were founded in (or on) Hartford Shale bedrock,...
Behavior of Instrumented Model Piers in Manufactured Rock with a Soft Layer
A laboratory test apparatus has been used to study the side resistance of piers socketed into manufactured soft-rock masses. The results of four tests are reported, three of which included...
Strength Design for Reinforced-Concrete Hydraulic Structures
Two Basic Concepts in Offshore Engineering
Two concepts are developed which lead to an improved understanding of the characteristics of the wave forces that act on deep-water, jacket-type offshore structures. The first concept...
Wind Effect on Oblique Motion of Two Bodies in a Uniform Flow
The wind effect on the general translational motion of a circular cylinder through an inviscid and incompressible fluid, conveyed by a uniform flow at infinity, in the vicinity of another...
The Generalized Brazier Problem for Orthotropic Straight Tubes of Finite Length
A new engineering approach, based upon a mixed variational functional, is presented for the analysis of the nonlinear static behavior of thin-walled, circular-cross-section cylindrical...
Mechanics of Granular Materials at Very Low Effective Stress Levels
Gravity's influence on laboratory specimens of uncemented granular materials subjected to low effective stresses, makes it impossible to evaluate constitutive properties in an unambiguous...
Stability of Beams in Eccentrically Braced Frames
As the link yields and strain hardens in an eccentrically braced frame, the beam segment-outside of the link is subject to a combination of high axial force and bending moment. For certain...
The Army Aviation Team from a Military Civil Engineer's Perspective
The Technical Session for which this paper is written is 'Airfield Pavements - A Team Effort.' As such, the emphasis on this paper is the United States Army Aviation Team, and not the...
Modeling Nearshore Currents in the Vicinity of the Endicott Causeway, Alaska
The Endicott Causeway connects two oil production islands on the southern side of Stefansson Sound, about 5 km offshore of the Sagavanirktok River delta, to the mainland of the Alaskan...
A Three-Dimensional Simulation of Buoyancy and Wind-Induced Circulation and Mixing in the New York Bight
A three-dimensional simulation of the circulation and mixing in the New York Bight has been conducted, forced by (i) wind stress for the year 1987 and monthly-mean heat fluxes at the sea...
Estimates of Extreme Wind Distribution Tails
The assumption that extreme winds have a Gumbel distribution appears to yield unrealistically high failure probability estimates for wind-sensitive structures. For this reason we study...
Sampling Errors in U. S. Extreme Wind Records
A study of design level extreme wind speeds showed that sampling errors were the primary cause of station to station variability. A method for decreasing sampling errors in design wind...
TLP Fatigue Due to Second-Order Springing
For offhsore oil production in water depths beyond 300-350 m, the tension leg platform (TLP) has become an increasingly popular design concept. The TLP is a floating structure with excess...
Port of Portland's Berth 601 Floating Dock
The Port of Portland's facilities, being located on the Columbia and Willamette Rivers, are subjected to extreme water level fluctuations. Over the years, the Port has used floating docks...
U.S. Navy Deployable Waterfront Facility
The U.S. Naval Civil Engineering Laboratory (NCEL) has been developing the concept of a Deployable Waterfront Facility (DWF) as part of its technology development programs for the enhancement...
Environmental Monitoring and Operator Guidance System (EMOGS) for Shallow Water Ports
Port facilities have increasingly been required to accommodate longer and deeper draft ships. Existing approaches to many ports consist of long shallow channels which can make transits...
Risky Business: Can We Believe Port Risk Assessments?
What is the risk that a maritime incident resulting in catastrophic consequences (environmental damage or loss of life) could occur in a U.S. port or waterway? How does one calculate the...
An Overview: Wetland Restoration, Protection, and Establishment by Beneficially Using Dredged Material
Dredged material has been used beneficially by mankind for many years; in the past two decades it has purposely been used to restore and protect existing wetlands, and to establish new...
Investigation of the Behavior of Reinforced Plastic Columns with Concrete Core
This paper describes an experimental investigation into the behavior of reinforced plastic columns with tubular (hollow) sections. The columns were pultruded and had a cross-section which...
