Binding and Bonding Concrete to Composite Columns
Composite interaction between concrete encasement and structural steel shapes is limited unless lateral ties and/or mechanical attachments insure such interaction until desired strength...
A Road to Recovery
Inspections of the Golden Gate Bridge revealed that the bridge had localized corrosion near its expansion joints, corrosion of its reinforcing steel, and was severely contaminated with...
Water Quality Modeling of Key Largo Coral Reef
A numerical model called CORALSIM has been developed for the Key Largo Coral Reef National Marine Sanctuary in the Florida Keys. The model was developed as a management tool to study the...
Direct Filtration of Colored Water Supplies
The effects of raw water quality, chemical treatment, and filtration variables on the performance of direct filtration are examined. Cationic polyelectrolytes as sole coagulants are effective...
Optimization of Design and Operating Parameters for Single-Media, Unstratified-Bed Filters
The potentially successful use of filters containing large grain-size single media for water filtration has prompted investigation of the parameters controlling the performance of these...
A Rule-Base Inference System for Liner/Waste Compatibility
Determining the chemical compatibility of a liner material for containment of wastes rests mainly on the application of expert opinion to interpret the results of short-term immersion...
Evaluation of PVC Bottom Linear From an Existing Landfill Located in a Subtropical Climate
Remedial action to curtail leachate seepage on a sanitary landfill located in a subtropical climate included the attachment of new PVC liner to an existing 20 mil PVC liner which has been...
Failure of a Large Reinforced Concrete Pipeline
This paper describes the damage that occurred when a landslide overloaded an 11 ft diameter reinforced concrete pipeline. The 8 ft lengths of pipe, each of 11. 5-in. wall thickness, were...
Buried Fiberglass Pipe Response to Field Installation Methods
In 1970 near Yuma, Arizona, a field test installation of 30 inch diameter fiberglass pipe was constructed. Twelve years later the pipeline was remeasured. Measurements of pipe profile,...
Strains Induced by Combined Loading in Buried Pressurized Fiberglass Pipe
In 1983 Owens Corning Fiberglas and Utah State University collaborated on a study of combined strain behavior of fiberglass pipe to quantify the bending strain reduction as a function...
Long Term Testing of Centrifugally Cast Glass Fibre Reinforced Plastic Pipes (RIRP)
The paper discusses testing of pipe manufactured by centrifugal molding. The tests included external load tests, internal load, hydrostatic internal pressure, and cyclic internal pressure....
Buried Fiberglass Pipe Performance and Installation Requirements and Design Calculations in International Standardization
This paper elaborates on a proposed standard covering details of fiberglass pipe buried installation requirements and criteria for selection of pipe stiffness. It also discusses the selection...
Successful Use of Centrifugally Cast Glassfiber Reinforced Plastic (GRP) Pressure Pipes for Public Works in Sweden
Centrifugally cast GRP pipes were introduced in Sweden 17 years ago for industrial applications mainly as a gravity pipe. The process of pipe manufacturing as well as the pipe itself and...
Proportioning Reinforcement for Buried Concrete Pipe
The proportioning of reinforcement between inner and outer cages that is specified in ASTM Standard Specification C76 for concrete pipe in sewer and culvert applications is examined in...
Nine Years' Service with Deep Polymer Impregnation
A test installation of deep polymer impregnation was applied to a heavily traveled bridge deck in Bethlehem, Pennsylvania, in 1975. The deep polymer impregnation process involved drying...
Composite and Mixed Construction
Steel and reinforced concrete are frequently combined in composite or mixed structural systems. This combination generally results isn greater economy and safety than could be achieved...
Membrane Sealing of Rouchain Dam
A synthetic sealing membrane was used to prevent excessive leakage through the facing of an embankment dam. The works, which were completed rapidly and at low cost, enabled the reservoir...
The R. D. Bailey Dam, a Concrete-Faced, Earth-Rockfill
A case history for the R. D. Bailey Dam, describing its comparatively unique design and construction considerations, and its operational performance since initial reservoir filling in...
Design and Performance of Shiroro Rockfill Dam
Shiroro Dam, constructed across the Kaduna River in Nigeria, is a rockfill dam with reinforced concrete facing. The dam was completed in late 1983, and reservoir impounding started in...
Khao Laem?A Concrete Face Rockfill Dam on Karst
A continuously reinforced concrete faced rockfill dam has been successfully designed and constructed on a karstic limestone foundation in Central West Thailand. The dam is not in an earthquake...
