Which type of steel bar is used in pre-stressed concrete structural elements?

Solution

Concept

Steel for prestressing

Step-by-step solution

1. Prestressing needs very high strength steel (high tensile wires, strands or bars).

Explanation

Only high tensile steel retains prestress after losses.

Why the other options are wrong

TMT and HYSD bars are too low in strength.

Shortcut

PSC = high tensile steel.

Correct answer: C) High tensile steel bars
