Reinforced and Prestressed Concrete Pressure Pipe Diagnosis
Prestressed and reinforced concrete steel cylinder pipes are used for transmission mains, water intake lines, sewers force mains. Many collapses caused by the steel cylinder attack were...
Relocating a 54-Inch Diameter Force Main without Interrupting Wastewater Flow
The City of Tampa, Florida, was faced with the challenge of relocating three segments of an old 1372 mm (54-in.) diameter reinforced concrete pipe force main, totaling nearly a mile in...
Pipelines Crossing Highways and Railroads by Tunneling
When new pipeline construction requires the crossing of highways and railroads, a pipeline is generally installed in pipe or tunnel linear plate encasement which has been installed by...
Chemical Resistance of Thermosetting Resins Used for Cured-in-Place Pipe
This paper summarizes the chemistry, short term physical properties, and long term chemical resistance for representative epoxy vinyl ester, epoxy, and polyester resins that are currently...
Controlling Corrosion in Bridge Structures
The overall objectives of the Structures Research Area of the Strategic Highway Research Program (SHRP) were to provide methods to protect chloride-contaminated concrete components against...
Electrochemical Treatment and Protection: Lessons Learned
Corrosion is recognized today as one of the major contributors to the deterioration of steel reinforced concrete structures. Two electrochemical techniques, chloride removal and cathodic...
Selecting Bridge Protection and Rehabilitation Options
This paper describes a recently developed procedure for use by bridge engineers making protection or rehabilitation decisions for concrete bridges. The methodology determines the most...
Cathodic Protection for Protecting Prestressed Concrete
Due to the good effect of corrosion protection of reinforcing steel bars, even in concrete highly chloride contaminated, cathodic protection for concrete structure now carried out as a...
European Way of Standardization in the Field of Underground Pipe Renovation
European standardization is carried out within the framework of CEN (European Committee for Standardization). The development of standards for underground pipe renovation is taking place...
Plastic Potential
Some 220,000 tons of epoxy-coated steel has been used in the construction of bridge decks since 1987, but some have raised questions about its long-term durability. New materials for prestressing...
Bonded Concrete Overlays for Rehabilitation of Continuously Reinforced Concrete Pavement
As a result of the 1991 Intermodal Surface Transportation Efficiency Act (ISTEA), significant funding is now available for the rehabilitation of the nation's Interstate highway system....
Silica Fume Concrete: A Solution to Steel Reinforcement Corrosion in Concrete
This paper discusses the utilization of silica fume concrete admixture to prevent reinforcing steel corrosion. The mechanism of steel corrosion in salt impregnated concrete is described,...
Characterization of Man-Made Vitreous Fibers by Image Analysis
This paper deals with the characterization of man-made vitreous fibers (MMVF), seen as an application of the techniques of image analysis and mathematical morphology. We present the whole...
Application of Radar Imaging Techniques to Concrete
Wideband radar imaging techniques have the potential of being a powerful tool in detecting steel reinforcing bars and delaminations inside concrete. The success of the method as a nondestructive...
Rehabilitation of Runway 4R-22L at Chicago's O'Hare International Airport
This paper describes the systematic process that was used to develop a rehabilitation strategy for the busiest runway at O'Hare International Airport. Any rehabilitation alternative that...
Finite Element Analysis of Reinforced Concrete in Japan and US: Introduction and Overview
The finite element method of analysis now provides the engineer with the capability to analyze very complex structural systems in a much more realistic manner including geometry and support...
Constitutive models
The constitutive models used in the finite element analysis of reinforced concrete structures are presented from a number of different perspectives. The first part of this chapter presents...
Reinforced Concrete
Recent developments and procedures used to model reinforced concrete using finite element analysis are summarized. Special emphasis is placed on the results of a survey of papers published...
Time-Dependent Behavior
This paper is a report of the material presented at the International Workshop on Finite Element Analysis of Reinforced Concrete, Session 4 - Time Dependent Behavior, held at Columbia...
Computational Aspects
In the past, two distinctly different approaches - smeared and discrete failure models have been adopted to describe failure mechanisms in plain and reinforced concrete structures. Although...
