Civil Engineering Prestressed Concrete

The exclusive video presented by Civil Engineering. In this tutorial briefly shows how to 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.

Prestressing tendons (usually of high tensile steel cable or rods) are used to provide a clamping load which produce a compressive stress that balances the tensile pressure that the concrete compression member would or else experience due to a bending load. Traditional reinforced concrete is based on the use of steel reinforcement bars, rebar, inside poured concrete.
