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,...

Effects of Freezing on Impact Properties of RTM Composites, and Their Applications in Offshore Structures
Resin transfer molding is rapidly being acknowledged as the process with potential to create perhaps the purest form of a composite material as representative of the concept of `material-by-design.'...
Fiber Ropes for Ocean Engineering in the 21st Century
Recent advances in synthetic fiber ropes will greatly influence the practice of civil engineering in the oceans during the 21st Century. New fibers have moduli almost as high as steel...
Composites for Offshore Applications: A Multidisciplinary Education Program for the Marine Industry
Composites are increasingly being considered for offshore and other marine structural applications. Polymeric matrix composites reinforced with glass, carbon, and aramids offer substantial...
Smart Structures
Detecting cracks in concrete before they become visible could help prevent structural collapse of buildings and other civil works, say professors at three schools of engineering. The University...
Tying Back a Landslide
A slope covered with landslide debris is never the most desirable site on which to build, but sometimes it is the only one available. For the Forks of Butte hydroelectric power project,...
Under the Undersea World
Soil conditions in New Orleans are generally unfavorable to the construction of large structures, and exceptionally so along the Mississippi River banks, which tend to slide. But that...
Dome Over Orlando
The article describes Orlando's new City Hall, a 267,000 sq ft nine-story reinforced concrete tower, clad in granite-aggregate precast concrete panels and topped by a 120...
Experimental Study of Adfreeze Heaving of Augered Caisson Footings
In order to establish the required depth of augered caisson-type footings in cold regions and their optimal design against adfreeze heaving, an experimental field investigation has been...
Earth Walls: Making the Right Choice
Earth walls are retaining walls where the ground assumes a load-bearing role. These walls either support compacted earth (embankment-type reinforced compacted earth walls such as Doublewal...
Improved Corrosion Protection for Flue Gas Systems Utilizing a Dual Liner Concept
A unique system of corrosion resistant materials has shown excellent performance and durability in flue gas systems for fossil plants, cogeneration plants, waste incinerators and waste-to-energy...
Advanced Composites Materials in Civil Engineering Structures
This proceedings of the Specialty Conference on Advanced Composites Materials in Civil Engineering held in Las Vegas on January 31?February 1, 1991 contains 40 papers from ten technical...
A Computerized Completion
The original designers of the 1.6 million sq ft Fillmore Center in San Francisco (its largest mixed-use development project in 20 years) had specified a large amount of steel reinforcement...
Behaviour of Plutonium, Rare Earth Elements and Elements of the Platinum Group in Vitreous Phosphate Composites During Liquid HLW Vitrification
The methods of ?-spectrometry, ?-scanning, ?-radiography, optical microscopy, x-ray phase and x-ray fluorescent analyses were used to study the behaviour of Pu, La, Ce, Nd, Sm, Ru, Rh,...
Cask Systems Development Program Seal Technology
General design or test performance requirements for radioactive materials (RAM) packages are specified in Title 10 of the U.S. Code of Federal Regulations Part 71 (10 CFR 71). Seals that...
Knowledge-Based Expert System Applications to Lateral Earth Support Structures
Knowledge-based expert systems (KBES) are computer programs, based on artificial intelligence (AI) techniques, designed to reach the level of performance of a human expert in some specialized...
Computer-Based Interactive Design for Prestressed Concrete Structures
Prestressed concrete structures can provide a highly desirable solution for many structural applications because the designer gains control over several additional parameters as compared...
Buckling Optimization of Laminate Stacking Sequence with Strain Constraints
An integer programming formulation for the design of symmetric and balanced composite laminates subject to buckling and strain constraints is presented. The design variables that define...
Optimal Design of Reinforced Concrete Structures via Decomposition and a Variety of Search Strategies
This paper presents a strategy where the design of a reinforced concrete structure is not only automated, but optimized. The strategy employs decomposition to subdivide the problem into...
