Prestressing is the process by which a concrete element is compressed, generally by steel wires or strands.
The purpose of reinforcement in prestressed concrete is to impart initial compressive stress in concrete
Precast elements may be prestressed during the construction process (pre-tensioning) or structures may be stressed once completed (post-tensioning).
Prestressing compensates for the tensile stresses introduced when the element is loaded. Hence the concrete generally remains in compression.
Prestressing serves two main purposes:
1. To improve the resistance of the member to the dead and live loads.
2. To modify the behavior of the member or structure in such a way so as to make it more suitable for its intended purpose.
The primary purpose of prestressing steel is to apply a force to a concrete, either by bond or by means of special anchoring devices.
