Advantages of Prestressed Concrete Bridges



Owners and designers have long recognized the low initial cost, low maintenance needs and long life expectancy of prestressed concrete bridges. This is reflected in the increasing market share of prestressed concrete, which has grown from zero in 1950 to more than 55 percent today.

This growth continues very rapidly, not only for bridges in the short span range, but also for spans in excess of 150 feet which, heretofore, has been nearly the exclusive domain of structural steel.

Behavior of instrumented prestressed high performance concrete bridge girders
A comprehensive monitoring of the behavior of four prestressed high performance concrete (HPC) bridge
girders, with higher compressive strength, during construction and while in-service, is discussed in this article. The instrumentation and monitoring of a group of four girders during the process of casting operation, after construction and under the conditions and influences of traffic and thermal loads, as well as under controlled load conditions is done.T ....etc

Fiber Reinforced Concrete
“FRC is defined as a composite material consisting of concrete reinforced with discrete randomly but uniformly dispersed short length fibers.”
Fibers are generally discontinuous, randomly distributed through out the cement matrices.
Enhances flexural and tensile strength of the concrete.
Fibers may generally be classified into two: organic and inorganic.
Contd. ….
Volume fraction – measure of fiber in concrete.
Typically ranges from 0.1 to 3%.
Aspect ratio - fiber length (l) ....etc
