PSC GIRDERS stressing process.

Question

Accepted Answer

PSC girders are stressed using hydraulic jacks to induce compressive forces in the concrete.

Prestressing is done to counteract the tensile stresses that develop in the concrete due to its own weight and external loads.
The stressing process involves placing high-strength steel wires or strands inside the concrete girder before casting it.
After the concrete has hardened, the wires are tensioned using hydraulic jacks, which induces compressive forces in the concrete.
The wires are then anchored to the girder ends to maintain the compressive forces.
This process increases the load-carrying capacity of the girder and reduces the amount of reinforcement required.
PSC girders are commonly used in bridge construction due to their high strength and durability.
