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.

Th ....etc

ABSTRACT
Road transportation is undoubtedly the lifeline of the nation and its development is a crucial concern. The traditional bituminous pavements and their needs for continuous maintenance and rehabilitation operations points towards the scope for cement concrete pavements. There are several advantages of cement concrete pavements over bituminous pavements. This paper explains on POLYMER FIBRE REINFORCED CONCRETE PAVEMENTS, which is a recent advancement in the field of reinforced concrete pavement design. PFRC pa ....etc

seminar report on prestressed concrete

Prestressed concrete is a method for overcoming concrete's natural weakness in tension. It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete. It is often used in commercial and residential construction as a foundation slab. Prestressing tendons (generally of high tensile strength steel cable or rods) are used to provide a clamping load which produces a compressive stress that balances the tensile stress that the concrete compression memb ....etc

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.Th ....etc
