Recent Developments in Composite Bridges
Composite steel and concrete bridges are becoming increasingly popular, in particular for short and medium spans. This renewed interest is due first of all to the great freedom for creativity...
PCCP Inspection and Remediation Methods
This paper presents detailed investigative procedures and methodology used to locate corroded Prestressed Concrete Cylinder Pipes (PCCP). It examines data collection by electronic devices,...
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...
Preventing Coating Delamination in Prestressed Concrete Pipe
This paper describes the results of experimental and analytical studies of mortar coating delamination of prestressed of concrete cylinder pipe. Coating delamination resulting from radial...
Modified Graphite Reference Electrodes
The primary aim of this research was to investigate the feasibility of developing an improved, more reproducible, reversible, and highly voltage invariant graphite reference half cell...
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...
Bonded Tendon Debate
Bonded tendons�currently banned in bridge construction in the United Kingdom because of corrosion concerns�are getting a bum rap, says the author. Corrosion protection details of most...
Behaviour of Prestressed Concrete End Blocks
This paper briefly reports on a series of experiments carried out on strip-loaded prestressed concrete end blocks. The results show that corresponding design methods presently used in...
Shear Resistance Models for Concrete Bridges
Statistical models are developed for the shear resistance of concrete bridge girders. Two structural types are considered: reinforced concrete T-beams and prestressed concrete AASHTO girders....
Nonprestressed and Prestressed FRP Sheets as External Reinforcement of Wood Members
The paper presents a summary of an analytical and experimental investigation of a new form of wood construction involving external bonding of thin fiber reinforced plastic (FRP) sheets...
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...
Prestressed Concrete Bridge Design and Optimization
The computer program described here analyzes simple span highway bridges for any AASHTO live load, generates girder and slab dead loads, performs the analyses for maximum moments and shears,...
Performance of a Prestressed Rigid Frame During Removal of Column 6W from I93 in Boston, Massachusetts
The first phase of the suppression of Boston's Central Artery included the Early Viaduct Construction in the Central Artery North Area. This project required that Column 6W...
Modular-Prestressed Shoring System for Demolition
