Question

Deflection of beams in pre-stressed concrete structures w.r.t. RCC structures is:
1. Equal
2. Less
3. More
4. Less or more

Answer 1

Correct Answer - Option 2 : Less

Explanation:

Prestressed concrete:

• Pre-stressed concrete is a form of concrete where initial compression is given in the concrete before applying the external load so that stress from external loads are counteracted in the desired way during the service period.
• This initial compression is introduced by high strength steel wire known as tendon located in the concrete section.
• The principle behind prestressed concrete is that compressive stresses induced by high-strength steel tendons in a concrete member before loads are applied will balance the tensile stresses imposed in the member during service.
• Deflection of the beam in prestressed concrete structures with respect to RCC structure is less.
