Pre-Compression of Concrete Breasting Dolphins Solves Construction Problem
A roll-on/roll-off ferry terminal was built in Quincy, Massachusetts in 1989 as part of a marine transportation system to support construction of the sewage treatment facilities proposed...
West Point Temporary Construction Dock
The West Point temporary construction dock is designed to provide construction access for the West Point treatment plant project located in Seattle, Washington. The dock plays a major...
Replacement of a Deteriorated Steel Sheet Pile Bulkhead
This paper presents a life history of a marine steel sheet pile bulkhead, over 35 years old, that has been exposed to a salt water environment with minimal maintenance or repair in the...
Seattle Swings Again
The 1992 Outstanding Civil Engineering Achievement Award went to a bridge that the experts said couldn't be built�a concrete segmental box girder swing bridge with twin leaves...
The OCEA Awards of Merit
Submerged rock weirs help tame the Mississippi River, high head pump storage provides power to a community safely and inexpensively, and the world's largest cantilevered hangar...
Building Better Bridges: Concrete Vs. Steel
The authors debate the merits of concrete segmental and steel bridge design and construction based on five criteria: initial and life-cycle costs; structural advantages; durability; construction...
The Role of Nondestructive Testing in Assessing the Infrastructure Crisis
At present the role of nondestructive testing in the evaluation of infrastructure deterioration is an extremely limited one. In the Author's experience this is, in part, due to a reluctance...
Realistic Specifications for Steel Bridge Painting
Specifications play a vital role in a steel bridge painting contract. They not only can ease problems with painting construction, but can also provide a common standard for all parties...
Bridge Deck Distress and Repairs
The primary cause of bridge deck deterioration are cyclic freeze-thaw exposures and reinforcing steel corrosion caused by the extensive use of de-icing salts. However, there are other...
Performance of Epoxy-Coated Steel in Continuously Reinforced Concrete Pavement
Two sections of interstate highway in central Oklahoma were recently reconstructed. On both projects, northbound lanes were reinforced with epoxy-coated steel and southbound lanes were...
Design and Construction of a Bonded Fiber Concrete Overlay of CRCP (Louisiana, Interstate Route 10, August 1990)
The purpose of this study was the design and construction of a bonded steel fiber reinforced concrete overlay on an existing 8-inch CRC pavement on Interstate 10 south of Baton Rouge,...
A Theoretical Approach to Characterize Reinforced Concrete Using Stress Waves
Although advances in nondestructive evaluation of structural concrete have been made, the ultrasonic determination of the placement of steel reinforcement in concrete remains difficult....
Bond Strength of Straight GFRP Rebars
An overview of a study on bond of straight Glass-fiber-reinforced-plastic (GFRP) rebars to concrete is presented. The 54 specimens to be tested include several variables, such as the mode...
Hybrid (FRP+Steel) Reinforcement for Concrete Structures
The most popular method to prevent corrosion of steel rebars and prestressing tendons is epoxy coating. This paper presents an alternative approach consisting in the combination of a fiber-reinforced-plastic...
Sprayed-Zinc Galvanic Anodes for the Cathodic Protection of Reinforcing Steel in Concrete
Corrosion of reinforcing steel bars (rebars), due to penetration of chloride ions from seawater affects the substructure of many bridges in marine service. In a new, low cost control method,...
Turning on the Waterworks
A new tunnel, two pumping stations, reservoirs and 150 mi of pipe have 23 municipalities in DuPage County, Illinois awash in Lake Michigan water, ahead of schedule and under budget. Bringing...
A Face-Lift for Lincoln
The 45-year-old Lincoln Tunnel is undergoing a sweeping rehab�from its ceiling on down to its roadway. Each of the three tubes (in the world's only three-tube underwater vehicular...
Corrosion Fatigue of Deepwater Offshore Materials
Evaluation of the fatigue life of offshore structures operating in depths of up to 10,000 feet (3,048 m) requires knowledge of the combined effect of axial and hydrostatic loading on the...
Simplified Methods for Assessment of the Structural Integrity of Existing Steel Jacket Platforms in the Gulf of Mexico
This paper presents the results of research to define a practical procedure for assessment of the structural integrity of existing steel jacket platforms in the Gulf of Mexico. An overview...
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...
