Advantages of Prestressed Concrete

Advantages of Prestressed Concrete

·        In case of fully prestressed member, which are free from tensile stresses under working loads.

·        The cross section is more effectively utilized when compared with a reinforced concrete section which is cracked under working loads.

  · Within   certain limits, a permanent will be counteracted by increasing the eccentricity of the prestressing force in a prestressed structural elements, thus effecting saving in the use of materials.

  · Prestressed    concrete members possess improved resistance to shearing forces, due to the effect of compressive prestress, which reduces the principal tensile stress.

  · The  use  of high strength concrete and steel in prestressed members results in lighter and slender members than is possible with reinforced concrete.

  · It is free  from cracks, contributes to the improved durability of the structure under aggressive environmental conditions.

  ·  The economy  of prestressed concrete is well established for long span structures.

  · A prestressed   concrete flexural member is stiffer under working loads than a reinforced concrete member of the same depth.
